  • Lottery-type ticket having a winner indication
    Patent number: 7059514
    Abstract: A lottery-type ticket having a winner indication that enables a player to quickly determine whether the ticket is a winning ticket. The ticket may be a scratch-off ticket or a break-open ticket. The winner indication may be hidden under a scratch-off zone or behind a pull-tab window that is independent and separated from the playing area. Alternatively, the winner indication may be proximate to one or more game indicia that are each hidden under a scratch-off zone or behind a pull-tab window. Speed of play is increased by enabling the player to determine whether the ticket is a winning ticket by either scratching off a single scratch-off zone or opening a single pull-tab window.
