[0001] This invention relates to an apparatus for playing a game, and in particular a game
of the type known as "noughts and crosses".
[0002] The game of "noughts and crosses" (also known as "tic-tac-toe") has enjoyed a wide
popularity for many years. The game in its simplest form can be played with a pen
and paper. In general two players take turns at marking positions within a matrix.
The object of the game is to achieve a line of markings, for example 3, and the first
player to do so is the winner.
[0003] There have been a number of physical representations of this game in which the paper
is replaced by a structure for holding game pieces. Usually, each player is given
a set of identical game pieces which generally differ from those of the other player
in some way, for example by colour.
[0004] A particularly successful prior art example of such apparatus is the game of "Connect
Four" (RTM). In this game the structure defining a planar matrix is oriented vertically
and the players are constrained to add pieces to the matrix only from the top. The
matrix in this case is defined as an array of parallel vertical channels.
[0005] A further aspect of game play is provided in that the pieces fall to the lowest unoccupied
position within a channel, that is either at the bottom or abutting a previously inserted
game piece. During game play, the number of game pieces within the channels build
up from the bottom as they are progressively added from the top.
[0006] An extra level of game difficulty is provided by the game rules which require that
four pieces rather than three must be aligned in order to win.
[0007] Prior art game apparatus also contains extensions of this concept into three dimensions,
for example a number of structure of the type described may be arranged so as to provide
a three dimensional matrix.
[0008] As consumers demand new games of ever increasing complexity, it is desirable to provide
a new game apparatus which combines the popular concept of "noughts and crosses" with
new aspects of game play and additional levels of skill.
[0009] In accordance with one aspect of the present invention we provide an apparatus for
playing a game comprising:
a number of game pieces;
a support structure having at least one channel wherein the channel is arranged to
co-operate with at least part of the game piece, such that the game piece may be guided
along the channel in a first direction; and
at least one non-return element located along the channel at a non-return position
and arranged to prevent the movement of the game piece past the non-return position
only in a direction opposed to the first direction.
[0010] The invention therefore provides additional possibilities for game play in games
such as "Connect Four"(RTM) by allowing game pieces to be guided along a channel in
the first direction whilst preventing them from returning past specific points along
the channel in the reverse direction.
[0011] In general a number of channels will be provided and arranged in parallel as a set.
Typically the channels will be arranged in a plane although other configurations are
possible. For example the channels themselves may be nonlinear or their respective
ends might be arranged in a nonlinear manner, such as along a curve. The invention
is not limited to the channels being of a particular configuration and examples include
tubes, grooves or parallel guides. However, typically the channels will comprise first
and second walls which are adapted to guide at least part of the game piece along
the respective channel.
[0012] In cases where the channels are not enclosed tubes or bores, it is not necessary
for every part of a game piece to be located within the channel. The game pieces may
therefore not be limited to a particular shape as long as at least part of them may
be located within the channel so as to allow the game piece as a whole to be guided
along the channel.
[0013] The non-return elements may take one of a number of forms although preferably each
will comprise a protrusion which extends into the channel and co-operates with one
of the channel walls or base (if present), to form a recess. The part of the game
piece within the channel may therefore be guided around the protrusion and recess
when moved in the first direction. Generally the recess will face the first direction
such that the part of the game piece will be guided into the recess when approaching
from the opposite direction along the channel.
[0014] Other examples of non-return elements include elements adapted to deform elastically
or move only through a fixed angle, allowing movement past them only in one direction.
For example such elements might comprise projections or tines angled along the first
direction which deform or move towards the sides of the channel when a game piece
moves past in the first direction but which are moved together to block the channel
when forced in the opposite direction. Similarly magnetic elements might be employed
to deflect suitable game pieces into recesses or against co-operating lips.
[0015] Preferably the channels are not enclosed but have at least one open side along their
length such that one edge of each of the first and second walls lies in an exposed
plane.
[0016] Entry of the game piece into the channel may be achieved by providing a first opening
at one end allowing the game piece to enter the channel in the first direction. A
corresponding second opening may be provided at the opposite end of the channel to
allow the game piece to exit whilst moving in the first direction.
[0017] In order to prevent the game pieces from leaving the second opening the apparatus
may typically further comprise a channel stop which is arranged to block the channel
and is preferably positioned adjacent the second opening to prevent a game piece from
either exiting the channel or entering it through the second opening.
[0018] The channel stop may be advantageously arranged to be movable between a first position
to block the channel, and a second position to allow a game piece to enter or exit
the channel. A biassing device may be provided to bias the channel stop in the first
position. The biassing device may be arranged to allow the stop to be moved to the
second position by a player.
[0019] The game pieces may take one of a number of forms which may in part be determined
by the form of the channel. Preferably however they will take the form of a disc having
first and second opposed surfaces and a projection positioned centrally upon one of
the surfaces and extending in a direction generally normal to the surface.
[0020] Typically the apparatus will further comprise a second set of channels similar to
the first set and arranged to overlie the first set in parallel and separated therefrom
by a gap defining a plane, such that the one edge of the walls of the first set of
channels face one edge of the walls of the second set of channels across the planar
gap. In this case the channels may be considered as being arranged in parallel opposing
pairs.
[0021] The apparatus may also be arranged such that the support structure has tubular members
arranged to separately enclose each pair of opposing channels, wherein the tubular
members have slits along each side positioned to correspond to the planar gap between
the channels, such that the planar gap is extended outside of the tubular members.
[0022] Advantageously the gap between the first and second sets of channels may be arranged
to be of a sufficient width to allow passage of a game piece along the channels when
the projection of the game piece is within the channel, wherein the channel walls
and/or edges of the slits of the tubular members prevent the projection of the game
piece from leaving the channel other than via the first or second openings. With this
arrangement, when only part of the game piece is located within the channel, the other
part may pass along the gap as the projection is guided along the channel.
[0023] Although the second set of channels may have their corresponding first directions
aligned with those of the first set, typically the first set of channels will have
the first direction opposed to that of the second set. Of course alternatively a number
channels within either set could be arranged to have first directions that are opposed
to other channels within the same set.
[0024] When the apparatus comprises two sets of channels, each set having aligned first
directions, then each set of channels may have corresponding channel stops such that
when the channel stops are in their first positions, the game pieces may only be inserted
in the first set of channels at one end of the structure and the game pieces may only
be inserted in the second set of channels from the other end of the structure.
[0025] In addition to the alignment of the first and second sets of channels, the non-return
elements of the first set of channels will be typically positioned opposite the corresponding
elements of the second set of channels.
[0026] Either or both of the non-return elements or channels may be positioned having an
equal spacing. Typically the non-return elements and the channels will be equally
spaced so as to form a matrix of game piece positions. In general, when the game pieces
are provided at least in part as discs, this spacing may correspond approximately
to the diameter of the discs.
[0027] The apparatus may also be arranged such that, in use, the channels are arranged substantially
vertically within the support structure and the apparatus may be provided with a suitable
pivot such that the structure may be rotated about a horizontal axis so as to invert
the channels. This is particularly advantageous when provided in association with
two sets of channels having opposed first directions as the apparatus may be inverted
to add game pieces from either end. The structure may alternatively be rotated about
two diagonal axes in order to invert it.
[0028] The arrangement of the channels having at least a vertical component allows the game
pieces to be guided along the channels under the action of gravity.
[0029] The invention is not limited by the number of channels provided or by the number
non-return elements provided within the channels although it will be appreciated that
large numbers of channels and non-return elements provide the scope for more complex
game play. Although the apparatus and game pieces may be formed from any suitable
material, they will preferably be constructed from a plastics material and have a
set of game pieces for each player which may be distinguished from each other by their
colour.
[0030] Some examples of apparatus according to the invention will now be described with
reference to the accompanying drawings, in which:-
Figure 1 is a general view of the support structure of a first example;
Figure 2 is a plan view, partly in section of the support structure, showing one set
of channels;
Figure 3 is a plan view of a game piece of the first example;
Figure 4 is a side view of the game piece of the first example;
Figure 5 is a view of one end of the support structure of the first example; and
Figure 6 is a illustration of an electronic game of a second example.
[0031] Apparatus according to a first example of the invention is shown in Figure 1. A support
structure generally indicated at 1 is formed from two component halves indicated at
2 and 3 respectively. The two halves of the structure 2 and 3 are overlaid and attached
together at a number of points. The support structure 1 effectively comprises two
end pieces 4 and 5 connected by a series of parallel cross members 6,7,8.... The two
halves of the support structure 2 and 3 are formed such that, when connected together,
a series of passages 9 are formed passing through the support structure 1. Each cross
member 6,7,8... has a corresponding passage 9 passing through it and each passage
9 extends through the end pieces 4 and 5 to terminate in openings 10 and 11 respectively
in each end piece. The openings 10,11 of the passages 9 have a width larger than the
cross members 6,7,8. To achieve this, each cross member has corresponding slits 12
and 13 positioned upon each side within the plane of the structure and running along
their length such that a flat item such as a disc having a diameter almost as wide
as the opening 10 or 11, may pass along the cross members despite their narrower width
by protruding from each side of the slits 12,13.
[0032] The apparatus is intended for use in an orientation such that the passages 9 are
arranged vertically within a plane. Therefore, the cross members will normally be
arranged vertically with the corresponding end pieces being positioned one above the
other.
[0033] The support structure 1 is also provided with two pivots 14 (only one shown in Figure
1), upon which the support structure 1 may be rotatably mounted to a stand 15 (not
shown). The pivots 14 are provided at positions half way along the end most cross
members at either end of the support structure 1 and thereby provide an axis of rotation
in the horizontal plane about the pivot points 14. The pivots 14 also contain corresponding
slots 16 running through the pivots, which extend the passage 9 through the pivots
so as to allow an item to pass down the passage 9 in the end most cross member.
[0034] Buttons 17 are provided at one end of the end pieces 4,5. The buttons are arranged
to operate moveable channel stops and entry stops, to be described in more detail
below.
[0035] The two halves 2,3 of the support structure 1 are identical in form, allowing ease
of manufacture. When connected together, the support structure 1 therefore exhibits
two-fold rotational symmetry about an axis passing through the pivot points 14.
[0036] Figure 2 shows the appearance of one half 2 of the support structure with the second
half 3 removed. Each cross member 6,7... has an outer casing 20 providing a smooth
external appearance to the apparatus. Within each cross member, first and second walls
21,22 are provided defining a channel 23 running along the passages 9 between the
first and second ends openings 10,11. The edges of the casing 20 lie within the same
plane as the edges of the walls 21,22, the edges of the casing 20 providing the edges
of the slits 12,13 which run along each cross member between the two halves of the
support structure 2,3. As can be seen from the Figure, the openings 10 and 11 are
elongate in the plane of the structure and are wider than the width of the cross members
in the plane. An item which may pass through the openings 10,11 may be passed along
the cross member by passing over the edges of the walls of the casing and channel
20,21,22. When the two halves of the structure are connected there is a gap between
the edges of the walls of the two halves and this gap forms the slits 12, 13.
[0037] The channel 23 provides an extension to the passage 9 into the plane of the Figure.
In each case, the passage 23 extends across the cross member and both end pieces 4,5,
the channel ending in channel openings 24,25 respectively which form part of the larger
openings 10,11. The channel openings 24,25 are also visible in Figure 1 where the
overlying of the two halves of the support structure provides correspondence between
the openings 24 and 25 of the two halves respectively. The openings 10,11 of the passages
9 are therefore elongate openings within the plane having symmetrical recesses (channel
openings) provided above and below their centre in a direction normal to the plane.
[0038] Returning to Figure 2, a number of non-return elements 26 are positioned at equal
spacings along the channels 23. The non-return elements in each case are formed by
a protrusion 27 which extends into the gap between the walls 21 and 22. The edges
of the protrusions 27 similarly align with the edges of the walls 21,22 and the casing
20. The protrusions 27 are angled in a downstream direction within the cross members,
such that an object moving along the channel 23 from channel opening 24 to the channel
opening 25 will be directed by the protrusion along the wall 21 and around its downstream
point and will continue further down the passage 23. Such a direction defines a first
direction of movement for the channels 23. During normal use of the apparatus, the
support structure will be arranged such that when an object is allowed to enter the
opening 24 this first direction will be aligned with that of gravity. The first direction
is shown by an arrow 28 in Figure 2.
[0039] The channels 23 are effectively diverted around the protrusions 27 as each protrusion
extends downstream and away from the second wall 22. A recess 29 is provided between
the tip of each protrusion and the second wall 22. In general, the channel 23 is aligned
with the first and second channel openings 24,25 apart from at the points of the non-return
elements in their respective non-return positions, where the protrusions 27 form one
wall of the channel and direct the channel out of line with the two openings and around
the recesses 29. The recesses 29 are therefore provided in a line between the first
and second openings and the channel in each case is brought back into line with these
openings between consecutive non-return positions.
[0040] When the apparatus is inverted by rotation about the pivot points 14, such that the
force of gravity is directly opposed to the first direction 28, an object within the
channel will be directed in this opposed direction into one of the recesses 29. The
non-return elements are provided in this manner at a number of non-return positions
along each cross member. Corresponding channels and non-return elements are provided
in each cross member such that the positions of the non-return elements form a matrix,
preferably of equal spacing.
[0041] A suitable shaped object inserted with the channel 23 through the channel opening
24 will, when the force of gravity is aligned with the first direction 28, be transported
down the channel around each of the respective non-return elements. In order to prevent
such an object exiting the channel at the point 25, a channel stop component 30 is
provided for each channel. The channel stop 30 simply extends into the channel and
blocks it at a point just beyond the last recess 29. For each channel of one half
of the support structure, channel stops 30 are provided at a similar position and
are connected together to a component 31. In each case, a second channel entry stop
32 (Figures 1,2) is provided to cover each of the openings 24 but not the wider opening
11. This prevents the direct insertion of objects only into the channel openings 25.
[0042] Each of the entry stops 32 is also connected to the component 31 and is arranged
such that when the channel 23 is blocked by the channel stop 30, the corresponding
channel opening 25 is also blocked by the entry stop 32.
[0043] The stops 30,32 and the component 31 are shaped such that the main part of the passage
9 remains unobstructed even when the channel is blocked.
[0044] The component 31 and the attached stops may be deflected in a horizontal direction
from a first rest position to a second position. As shown in Figure 2, the end of
the wall 22 is positioned such that the channel stop 30 may move past it in a direction
indicated by the arrow 33. Similarly, the entry stop 32 may move past the edge of
the channel opening 25. The end of the component 31 extends out of a hole in the support
structure 1 and forms a button 17 which may be depressed by a game player. A spring
34 is provided between a projection attached to the component 31 and an extension
to the wall 21 in order to hold the component when at rest so as to block the channel
23.
[0045] When a player presses the button 17 the component 31 moves in the direction of the
arrow 33 by compression of the spring 34. The movement of the component allows access
to the channel and corresponding channel opening.
[0046] When the force of gravity is aligned with the first direction 28, an item resting
against the end of the channel stop will be allowed to pass out of the apparatus through
the channel opening 25. However, when the apparatus is inverted and the opening 25
forms the top of the channel, the entry to the channel of an item will only be allowed
if the button is depressed.
[0047] It is important to note that the two halves 2,3 of the structure 1 are identical
and are not mirror images of each other. Therefore, when the second half of the structure
1 is overlaid onto the first half, the first direction, the protrusions 27 and the
first and second ends of the channel are all reversed. Referring to Figure 2, whereas
the first half shown in the Figure has a first direction and protrusions directed
to the left hand side of the diagram, the second half of the structure overlaid onto
the Figure such that the sets of channels face each other, would have a respective
first direction and protrusions directed to the right.
[0048] Therefore, the component 31 is provided in the opposite end piece of the structure.
Each cross member and end piece therefore has a passage 9 passing along its centre.
However, along the side of each passage in the respective halves of the structure
lie channels and non-return members having opposed directionality.
[0049] The two halves of the support structure are joined at a number of points 35 in Figure
2 (also shown in Figure 1). It should be noted in Figure 2 that the end piece 4 of
the half structure not containing the component 31 has a central raised portion 36,
lying between the two channels. When the second half is placed upon the first half,
the central portions 36 hold the components 31 within their corresponding recesses.
[0050] Figure 3 shows a game piece for use in association with the apparatus, as viewed
from above. The game piece 40 comprises a flat circular disc having a projection 41
arranged centrally and extending out of the plane of the disc. This is shown more
clearly in the side view of Figure 4.
[0051] Figure 5 shows the appearance of the support structure 1 when viewed from one end
in a direction along the channels. The openings 10 of the passages 9 in the end piece
4 are shown, including the additional channel openings 24 and 25 from the respective
halves of the structure 2,3 forming part of the opening 10. The passages 9 pass completely
through the structure from the openings 10, the passages at all points having a cross-section
equal to at least the cross-section of the major elongate rectangular portions of
the openings 10.
[0052] In each channel opening 25 the entry stops 32 are visible. These openings are shown
corresponding to the lower half of the structure in the Figure. The button 17 is also
shown in the Figure, forming the end of the component 31 which, when depressed, moves
the internal channel stops and the corresponding entry stops 32 clear of the openings
25.
[0053] It will be appreciated therefore that were the apparatus to be viewed from the other
end, the position of the button would be reversed and the entry stops would be present
in the upper rather than the lower channel openings.
[0054] Referring to Figures 4 and 5, the game piece 40 may only be inserted in one orientation
into the end of the apparatus as shown in Figure 5. That is, with the main body of
the game piece passing through the large rectangle 10 whereas the projection 41 passes
through the upper channel opening 24 into the channel. However, the dimensions of
the openings 10,11 are only just larger than the corresponding disc thickness. Therefore
if two game pieces were added to the same passage from opposite ends so as to move
along the two respective opposed channels, they would not be able to pass one another.
This is advantageous as the walls of the channel and casing on the opposite side of
the cross member guide the game pieces and prevent them from falling out of the channel
[0055] When the apparatus is oriented such that the end piece shown in Figure 5 is at the
top of the apparatus and the passages are oriented vertically, the game piece will
fall by the action of gravity towards the bottom of the apparatus. The majority of
the game piece will pass unhindered through the apparatus. The projection 41 is formed
of suitable dimensions such that it remains located within the channel as the game
piece moves along the cross member in question under the action of gravity.
[0056] Any game piece which is held within the channels is visible externally to the game
players as the diameter of the game pieces is larger than the width of the cross members.
The game pieces therefore simply protrude from both slits on either side of the cross
members.
[0057] Referring to Figure 2, a game piece inserted into the right hand side of the apparatus
through the channel opening 24 will be moved in the first direction by gravity along
the channel, bypassing the non-return positions and eventually abutting the end of
the channel stop 30. A second game piece added to the channel 23 will move down the
channel until it abuts the first game piece. The non-return elements are spaced at
a distance approximately equal to the diameter of the game pieces such that, when
the first game piece abuts the channel stop 30, the projection of the second game
piece will be located at an approximate position marked 42 in the Figure.
[0058] If the apparatus is then inverted such that gravity acts in a direction opposed to
the first direction 28, the game pieces will be compelled to move in a direction directly
opposed to the first direction. The projections lying within the channels will therefore
move a short distance until they are held within the recesses 29 of the non-return
elements. Therefore, during a game, a game piece added to the top of the apparatus
will be guided to the lowest point available, that is either with its projections
resting against the channel stop, or with its main body periphery resting against
that of another game piece. The inversion of the apparatus causes all of the pieces
which were added from the former upper end to fall into corresponding recesses.
[0059] It is then possible to add further game pieces to the apparatus from the new upper
end. Because the non-return elements hold any game pieces in their former positions,
it is not possible to add a game piece to a passage which has already had a game piece
inserted from the opposite end, as such a game piece will be held at the top of the
apparatus, blocking the passage 9.
[0060] Therefore, the game pieces can only be effectively added to either previously unused
passages or ones in which any added game pieces were added from the same end.
[0061] The entry stop 32 prevents the addition of game piece projections to channels where
they would simply fall into the first recess and therefore any pieces added to the
top of the apparatus will always descend to the lowest unoccupied position.
[0062] At the end of a game, the game pieces may be removed from the apparatus by depressing
the lowermost button 17 when the apparatus is oriented in one of its two vertical
orientations. Any pieces which were added to the opposite end of the apparatus with
respect to the component 31 will therefore fall from the bottom of the apparatus due
to the movement of the channel stop. It may therefore then be necessary to invert
the apparatus and perform a similar action to release game pieces occupying the recesses.
[0063] Each channel in a set is substantially identical and by providing the apparatus with
a large number of parallel cross members, each having a large number of non-return
elements, a challenging game may be created.
[0064] Generally, the game will be played by two or more players each having for example
a specific set of coloured game pieces. The object of the game may be similar to that
of Connect Four(RTM) in that the winning player will be the one who first aligns four
game pieces of the same colour in either a vertical, horizontal or diagonal direction.
Therefore, the cross members will generally be spaced such that game pieces in adjacent
cross members may pass one another without touching, however the spacing of game pieces
in either horizontal or vertical directions will be approximately similar so as to
create a matrix effect regardless of whether the pieces are simply abutting under
gravity or are each held in respective non-return elements.
[0065] The apparatus may therefore be used in a similar manner to a conventional Connect
Four(RTM) game by maintaining the game structure in one vertical orientation. However,
in most cases a great deal of further complexity may be added by allowing either of
the game players to choose an orientation in which to add the game pieces to the passages.
In this way, game pieces may be added from either end of adjacent passages such that
eventually there may be lines formed having component game pieces which have been
added to the apparatus from opposite ends of the structure.
[0066] One example of a game that may be played in accordance with the present invention
will now be described with reference to two players denoted player 1 and player 2.
[0067] The game is a development of Connect Four(RTM). The object of the game is to be the
first player to arrange their game pieces in a line of at least four pieces. Such
a line may be arranged horizontally, diagonally or vertically with respect to the
vertically arranged parallel channels of the game.
[0068] Generally the game will be played by two players, each having a corresponding set
of game pieces. At the start of the game the players each choose a set of game pieces
which may be distinguished by colour, for example one set being red for player 1 and
the other yellow for player 2.
[0069] Player 1 begins the game by selecting a red game piece from their set. The channels
are aligned in a vertical direction according to a first orientation. This may be
either of two possible starting vertical orientations. Player 1 inserts the game piece
into the top of one of the channels. The game piece is guided to the bottom of the
channel by gravity and comes to rest at the bottom of the channel.
[0070] Player 2 then selects a yellow game piece from their set. Player 2 now has two options
according to the game rules. Firstly, player 2 may insert their game piece into the
top of any one of the channels, including the one selected earlier by player 1. In
this case, the game piece of player 2 is guided down the selected channel and either
comes to rest at the bottom of the channel, or if the channel is that selected earlier
by player 1, the yellow game piece is guided downwards until it abuts the red game
piece of player 1.
[0071] The second and alternative option available to player 2 is to "flip" the channels
such that they become inverted. The inverted channels adopt a second orientation with
respect to the first orientation. Inverting between the first and second orientations
and vice versa may be performed any number of times whilst the players are selecting
a channel in which to place a game piece. If this option is chosen, the game piece
of player 1 that was at the bottom of the channel in the first orientation will now
be positioned at the top of the channel in the second orientation. Player 2 may now
add their game piece to the any of the channels in the second orientation except the
one containing the game piece of the player 1 (as this will block the opening). The
game piece of player 2 will then be guided to the bottom of the channel (in the second
orientation).
[0072] Player 1 may then add a game piece to the channels in either orientation as long
as their respective openings are not blocked by a game piece added earlier.
[0073] The game continues in this manner with each player taking turns to add a game piece.
At any time, all game pieces added by either player at an earlier time are maintained
in the position in which they came to rest under the action of gravity, regardless
of whether the channels are in their first or second orientation.
[0074] As the game pieces added in either orientation are visible externally when located
within the channels, the game is won when one player first achieves a line of four
of their game pieces anywhere within the matrix of possible game piece positions.
This can therefore be seen.
[0075] The number of games won by each player may be indicated by a suitable device. For
example an unused game piece may be inserted in one of a number of slots. A set of
numbered slots may be provided for each player, the number of the slot in which the
piece is contained denoting the number of games won by the respective player.
[0076] It will be appreciated that the apparatus for playing the game as described above
can be represented at least in part as an electronic game.
[0077] A second example will now be described with reference to Figure 6. An electronic
game system is provided with a control processor 50. A display 51 is provided upon
which the game apparatus and game pieces are represented under the control of the
processor. A store 52 is arranged to communicate with the processor and contains data
associated with the game. Interaction between one or more users of the game system
and the processor is provided using an input device 53. Appropriate sound effects
are provided to accompany the game through the speaker 54 under the control of the
processor. The game software is stored in non-volatile memory 55, for example on one
or more suitable ROM devices.
[0078] The apparatus may be provided as a dedicated game device or might generally represent
a computer such as a personal computer in which the game is represented as software.
[0079] In a dedicated game device, the display may comprise a number of lights 56,57,58...
arranged in a matrix to represent each possible position of the game pieces in the
channels. A game piece may therefore be represented by an illuminated light and respective
game pieces for each player may be represent by different coloured lights under the
control of the processor 50. Two lights of different colours may therefore be provided
at each possible game piece location. More advanced displays may be provided by the
use of liquid crystals or other known devices.
[0080] Whilst the non-volatile memory 55 contains the instructions to control the processor,
the store 52 is arranged to store data relating to the positions of the game pieces
during the game, along with game preferences and high scores. Any suitable recordable
memory storage device may be used for this purpose.
[0081] The game is controlled using the input device 53. Typically this will contain buttons
allowing a player to select a column in which to place a game piece, a button to indicate
the end of a player's turn, along with a "flip" button to invert the virtual apparatus.
Other mode, ON/OFF, and menu buttons may be provided to allow easier control of the
game. For example one mode may not allow the inversion of the virtual apparatus, thereby
reverting the game to that of conventional Connect Four(RTM).
[0082] A game is initiated once a player presses the ON button. A single or two player mode
may then be selected in accordance with the display, along with further options. In
the single player mode, the processor replaces the second player and the user is able
to choose a specific skill level for the opponent represented by the processor.
[0083] In a two player game, the first player is asked to select a column in which to place
a piece. In this example a button is placed below each column indicated on the display.
Pressing the button below a column causes the processor to switch on and off the coloured
lights from the "top" of the column in sequence from the top of the display to the
lowest unoccupied position. This represents a piece falling down the column. For the
first game piece to be added, this position will be at the bottom of the respective
column, for example position 60 in the Figure. Only the lights representing the first
player are used and once the game piece has reached the lowest unoccupied position,
the light at that location of the player's assigned colour remains illuminated.
[0084] After pressing the button to indicate the end of their turn, the game piece position
(as represented by the illuminated lights) and the player to whom it belongs is stored
in the store 52. The second player then chooses a column in the same way. The processor
recognises the change of player as an instruction to operate the lights of the second
colour in response to a column selection.
[0085] The second player may add a game piece to any column which does not have game piece
at the top (as indicated by a light, for example light 61). Alternatively by pressing
the "flip" button the player may invert the virtual apparatus such that the piece
already indicated by a glowing light becomes positioned at the top of the channel
rather than the bottom. The new position is determined by the processor in accordance
with the data in the store. The addition of a piece by the second player is represented
by the appropriate lights being operated in sequence to represent a game piece falling
within a channel.
[0086] The game continues in turn with each player being given the option to either add
a game piece or to invert the virtual apparatus and then add a piece. Whenever the
"flip" button is pressed, the virtual apparatus is inverted and the game pieces are
held in their respective new positions as they would be in reality by the non-return
elements.
[0087] The processor assesses the data in the store at the end of each player's turn. When
the processor determines that a player has aligned four pieces then the winning player
is indicated and a score may be assigned, for example based upon the time elapsed
or the number of pieces added.
