Substrate with hidden images and method of making such images appear

A game card having a hidden game image thereon that is developed over a predetermined period of time comprising:

• a front part and a rear part;
• the rear part including:
• a migrating ink pattern layer overlaying a rear support member to form a game image;
• a non-migrating printed pattern layer overlaying the rear support member to form a confusion pattern to hide the game image;
• the front part including a front support layer having an adhesive layer on one side and a front ink display surface on the other side, the adhesive layer capable of causing the migrating ink pattern to migrate upon contact therewith, whereby contacting the front part with the rear part by applying the adhesive layer onto the ink pattern layer activates the migration of ink in a selected time interval from the ink pattern layer across the rear support member to form the game image for viewing through the front ink display surface.

A method of playing a game ticket comprising:

• providing a game ticket having a hidden image thereon that is developed over a predetermined period of time, the game ticket comprising:
• a front part and a rear part;
• the rear part including:
• a migrating ink pattern layer overlaying a rear support member to form a game image;
• a non-migrating printed pattern layer overlaying the rear support member to form a confusion pattern to hide the game image;
• the front part including a front support layer having an adhesive layer on one side and a front ink display surface on the other side, the adhesive layer capable of causing the migrating ink pattern to migrate upon contact therewith,
• contacting the front part with the rear part to thereby apply the adhesive layer onto the ink pattern layer and activate 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 to determine if it is a winning or losing game ticket.
