Wagering Requirements At Mars Casino
A wagering requirement (wager) is the number of times you must bet the bonus amount, or the bonus plus deposit, before you can withdraw bonus-related winnings. Mars Casino counts only eligible real-money bets, and it deducts void, cancelled, or cashed-out bets from progress.
- Example 1: You claim a $100 bonus with a 35x bonus-only wager. You must place $3,500 in eligible bets ($100 × 35) before you can withdraw winnings from that bonus.
- Example 2: You deposit $200 and receive a $200 bonus with a 30x (deposit + bonus) wager. The wagering base is $400, so you must place $12,000 in eligible bets ($400 × 30) before withdrawal of bonus-related winnings.
