Wagering Requirements At Mars Casino
At Mars Casino, a wagering requirement (often called a “wager”) is the total amount you must stake on eligible games before a bonus balance and any winnings from that bonus can be withdrawn. Mars Casino calculates it as: bonus amount × wager multiplier, and only bets placed with the bonus (or bonus-converted funds) count toward the target.
- Example 1 (100% bonus, 35x): You deposit $100 and receive a $100 bonus with a 35x wagering requirement. Your wagering target is $100 × 35 = $3,500 in eligible stakes before withdrawal of bonus-related funds is allowed.
- Example 2 (free spins, fixed value, 40x): You receive 20 free spins worth $0.20 each ($4 total). Winnings from the spins convert into a bonus balance with a 40x requirement. If you win $18 from the spins, the wagering target is $18 × 40 = $720 in eligible stakes before those winnings can be withdrawn.
