ABSTRACT:
A game card having a hidden game image thereon that is developed over a predetermined period of time. The game card includes a front part and a rear part. The rear part has a migrating ink pattern layer overlaying a rear support member to form a game image. An non-migrating printed pattern layer overlays the rear support member to form a confusion pattern to hide the image. The front part includes a front support layer having an adhesive layer on one side and a front ink display surface on the other side. The adhesive layer 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, the adhesive layer activates the migration of ink in a selected time interval from the ink pattern layer, through the adhesive layer to the front ink display surface for viewing the game image. Typically, the game image is capable of informing the user whether the game card is a winning card or a losing card.
