Seal card games contain a special seal card that determines the winner(s) of the larger prize(s). Typically, seal cards will include a predetermined number of signature lines that correspond to the number of hold tickets in the deal. Players that find hold tickets may sign their name on the seal card. Once the entire deal is sold, the window on the seal card is opened by the operator to reveal the sign up number of the grand prize winner(s).
Seal card games typically offer an option to provide one large prize for a single winner or split the prize into smaller amounts for multiple winners. For example, with Diamond Daze™, there is a total of $500 to be awarded. The operator may choose to award a single winner with a $500 prize, two winners with $250 prizes, or five winners with $100 prizes.
