Abstract (en)

[origin: WO9839164A1] A game card (10) having a hidden game image thereon that is developed over a predetermined period of time. The game card includes a front part (12) and a rear part (14) having a migrating ink (44) pattern layer overlaying a rear support member to form a game image (44). A non-migrating printed pattern layer (38) overlays the rear support member to form a confusion pattern to hide the image. The front part includes a front support layer (30) having an adhesive layer (32) on one side and a front ink display surface on the other side. The opaque adhesive layer (32) is capable of causing the migrating ink pattern to migrate upon contact therewith. Thus when the front part is contacted with the rear part by applying the adhesive layer onto the ink pattern layer, through the adhesive layer to the front ink display surface for viewing the game indicia (44). The game image (38) is capable of informing the user whether the game card is a winning card or a losing card.
