[0001] The invention relates to a game of skill of an entirely new type. The closest prior
art is formed by the generally known game of roulette. Such game of roulette comprises
a betting table bearing a print with symbols on which betting can take place by means
of chips, coins or like objects of value. Further, the known game of roulette comprises
a playing apparatus provided with a ball input tray, in which ball input tray there
is also arranged a circle of symbols which is rotatably supported. When the game is
played, a croupier throws a ball into the ball input tray and gives the circle of
symbols a push, causing it to rotate. After some time, the ball hits the circle of
symbols or other uneven parts provided in the input tray, so that the regular path
of the ball in the ball input tray is disturbed and the position in which the ball
eventually ends up on the circle of symbols is unpredictable. Hence, the known game
of roulette is a game of chance, where the player's skill does not play a part whatsoever.
[0002] The object of the invention is not to provide a game of chance, but a game of skill,
in which the player, if he or she has the required skill, can increase his or her
chance of winning.
[0003] To this end, according to the invention, the game of skill comprises a betting table
and a playing apparatus, the betting table having a print with symbols on which chips,
coins or like objects of value can be betted, the playing apparatus being provided
with a ball input tray having a concave surface which is rotational-symmetrical around
a center with an opening at the location of the center of the surface, which opening
opens into a passage extending below the concave surface and terminating into a circumferential
area extending around or below the ball input tray, a circle of symbols that is subdivided
into sections being located in the circumferential area, while at each section there
is provided a symbol corresponding to a symbol on the betting table, the circle of
symbols being rotatable relative to the passage.
[0004] As the path of the ball in the ball input tray is in each case substantially identical,
the player who bets his chips on the betting table can predict, depending on the position
of the ball at a given moment in the ball input tray together with the position of
the circle of symbols at the same moment, which symbol is situated before the outlet
of the passage at the moment when the ball rolls out of this passage and lands on
the circle of symbols, and hence in which section the ball will eventually end up.
Due to this predictability, the player, during betting of his chips, can increase
his chance of winning. Preferably, the ball input tray will have its outer circumferential
edge provided with a vertical wall part, preventing a ball thrown into the ball input
tray from rolling out of the tray. When the ball is thrown into the ball input tray,
this ball will first roll along the vertical wall part for some time. After a while,
the ball comes loose from the vertical wall part and rolls slowly across the preferably
frustoconical surface of the ball input tray towards the opening at the center of
the surface. A good moment for determining the position of the rotating circle of
symbols or the rotating passage relative to the position of the ball is the moment
when the ball releases the vertical wall part. The path then to be traveled by the
ball will in each case be substantially identical, so that the time needed for the
ball to reach the outlet from that moment onwards is in each case substantially identical,
so that the circle of symbols or the passage always makes the same number of rotations,
at least when the circle of symbols or the passage rotates at a known speed. In that
manner, it is possible to predict in which section on the circle of symbols the ball
will eventually end up.
[0005] In accordance with a further elaboration of the invention, it is particularly favorable
when the circle of symbols or the passage is driven by a drive motor, with the drive
preferably taking place at a constant speed. Accordingly, unlike roulette, the rotary
speed of the circle of symbols or the passage cannot be influenced by the croupier.
This influences the predictability of the game of skill considerably.
[0006] The invention also relates to a playing apparatus apparently intended for a game
of skill according to the invention.
[0007] Further elaborations of the invention are described in the subclaims and will hereinafter
be further clarified, with reference to the accompanying drawings.
Fig. 1 is a top plan view of the betting table and the playing apparatus;
Fig. 2 is a sectional view taken on the line II-II in Fig. 1 of the playing apparatus;
and
Fig. 3 is another top plan view of the playing apparatus, the ball input tray and
the playing circle having been made transparent, so that the parts located therebelow
are visible.
[0008] In the top plan view of Fig. 1, the betting table 1 and the playing apparatus 2 are
clearly shown. The betting table 1 is provided with a print with symbols 4 on which
chips, coins or like objects of value can be betted. The playing apparatus 2 is provided
with a ball input tray 5 comprising a concave surface 6 which is rotational-symmetrical
around a center M and with an opening 7 at the location of the center M of the surface
6. In the present exemplary embodiment, the concave surface 6 is designed as a frustoconical
surface 6 whose truncated side faces down. If so desired, the angle of inclination
of the ball input tray adjacent the opening 7 may be slightly steeper than the angle
of the ball input tray at the parts of the ball input tray that are situated more
radially outwards. Connecting to the upper outer circumferential edge 6a of the frustoconical
surface 6 is a vertical wall part 15, preventing a ball thrown into the ball input
tray 5 from rolling out of the ball input tray 5. The central opening 7 opens into
a passage 8 which extends below the concave surface 6 and terminates, via an outlet
9, into a circumferential area 10 extending around the ball input tray 5. Located
in the circumferential area 10 is a circle of symbols 11, subdivided into sections
12. At each section 12 there is provided a symbol 13, corresponding to a symbol 4
on the betting table 1. The circle of symbols 11 is arranged for rotation in a frame
14. For that purpose, the circle of symbols 11 is supported by means of a bearing
assembly comprising a bearing ring 16 which is fixedly connected to the bottom side
of the circle of symbols 11. Connected to the frame 14 are a number of first bearing
wheels 17 having a vertical axis of rotation 17a, which first bearing wheels 17 engage
the bearing ring 16 for stabilization of the circle of symbols 11 in horizontal direction.
The bearing assembly also comprises a number of second bearing wheels 18, each having
a horizontal bearing axis 18a. The center lines of the respective horizontal bearing
axes 18a intersect an imaginary vertical line extending through the center M of the
circle of symbols 11. The second bearing wheels 18 engage a bottom side of the circle
of symbols for stabilization of the circle of symbols 11 in vertical direction.
[0009] Further, in the present exemplary embodiment, the playing apparatus 2 is provided
with a drive motor 19 mounted on the frame 14, for rotatably driving the circle of
symbols 11. Preferably, the circle of symbols 11 is driven at a constant speed. The
drive motor 19 comprises a drive pulley 20 engaging a drive belt 21, which drive belt
21 engages an outer circumference of the bearing ring 16, which bearing ring 16 is
engaged, on an inner circumference thereof, by the first bearing wheels 17.
[0010] The frame 14 further comprises setting means 22 for accurately setting the circle
of symbols 11 together with the ball input tray 5 in horizontal position. In the present
exemplary embodiment, the frame 14 comprises three legs 14a, 14b, 14c, of which at
least two legs 14a, 14b are provided with said setting means 22 for setting the length
of the relevant legs 14a, 14b, and, accordingly, for accurately setting the circle
of symbols 11 together with the ball input tray 5 in horizontal position.
[0011] Of course, the symbols 4, 13 can be realized in various manners. In the present exemplary
embodiment, the symbols 4, 13 are formed by a number in combination with a color,
for instance red or black. In the present exemplary embodiment, the symbols 4 on the
betting table 1 are provided in the same manner in which the symbols of a game of
roulette known per se are provided on the betting table associated with a game of
roulette.
[0012] Preferably, the passage 8 has a downwardly directed course from the central opening
7 to the outlet 9, so that a ball 8 can travel through the passage 8 under the influence
of gravity. In the present exemplary embodiment, the ball ending up in the central
opening 7 falls on an inclined face 23 and is thus given an impulse in horizontal
direction, as a result of which the ball will travel by itself through the passage
8.
[0013] Optionally, each section 12 of the circle of symbols 11 may be provided with a sensor
adapted to detect the presence or absence of a ball, the sensor being connected to
a computer, to which computer a display is connected. On such display, the symbols
on which the ball has successively fallen can then be displayed.
[0014] It is readily understood that the invention is not limited to the exemplary embodiment
described, but that various modifications are possible within the framework of the
invention. Instead of disposing the circle of symbols in the frame for rotation, as
described in the exemplary embodiment given, it is also possible to arrange the circle
of symbols in a fixed position and to arrange the passage so as to be rotatable about
a vertical axis extending through the center M. Preferably, the passage is driven
at a constant speed. It is observed that the ball input tray may also be rotatably
arranged in the frame, if so desired. Further, the playing apparatus could be provided
with two or more passages, enabling the ball to end up in different places in the
circumferential area. Unlike the exemplary embodiment shown, the betting table may
also be disposed around the playing apparatus. The betting table could then be arranged
for rotation around the playing apparatus. Instead of a belt drive mechanism, the
circle of symbols may be driven via a gear transmission. Instead of being located
around the ball input tray, the circle of symbols may also be located in an area below
the ball input tray. In that respect, it is preferred that the vertical center line
of the circle of symbols intersect the center of the ball input tray.
