Most games have a 100 percent contribution rate. Regular slot games, Keno, Bingo Bucks, Poker Slots, and Dazzling Dice all have a 100 percent contribution rate. Most table games (including blackjack) and video poker have a contribution rate of $10. When playing slots, the max bet is $2 per single payline and $10 on any single wager; any wager that exceeds those amounts will negate the bonus.
Also, Roulette, Baccarat, and Craps don't contribute to the wagering requirement. In fact, wagers on these games with bonus cash negate the bonus, so don't play baccarat, roulette, or craps until you've cleared the requirement.
