Maximum bet rules are a pitfall for the uninformed. While you’re playing with bonus money, you cannot place a single bet above a set limit—often $5, $10, or a percentage of the bonus. Break this rule, and the casino will probably take back the bonus and any winnings you’ve earned. They have this rule to prevent people from using a small bonus to make a few huge bets hoping for a jackpot. To avoid issues, I determine my own bet limit lower than the casino’s maximum. I also review the terms for any extra bet limitations on specific games before I start playing with the bonus cash.
