Slot Machine: Regional Variations: United States: Slot machine classes: Class II game characteristics

The player is playing against other players and competing for a common prize.
There is certain to be a winner in each game. The game continues until there is a winner.
In a given set there are a certain number of wins and loses. Once a certain combination has happened it cannot happen again until a new batch is initiated. This is most obvious in scratch card games that come in a pack. Once a card has been pulled those winning combinations cannot occur again until a new pack of cards is installed. One game is dependent on previous games.
The player must be an active participant. They must recognize events as they occur and must recognize when they have won and announce their winning. Bingo is an excellent example here.
All players play from the same set of numbers as they are announced.
