(1) A bingo game ends when a player achieves a specific pattern on a bingo card or when the bingo operator has called a specific number of bingo balls.

(2) Operators must use a separate drawing process for each game, except for:

(a) Interim or "on-the-way" games, including "instant winner" games in which players win by matching a predetermined number, the number of balls called, or a predetermined pattern within an established number of calls; or

(b) Games in which cards are sold for different prices and players win a different prize depending on the price they paid to play; or

(c) Bonus games played at the same time as other bingo games where the player wins by calling a valid bingo that includes a predetermined number.
