Enter it at registration to claim a 125% first-deposit bonus up to $400 and 250 free spins distributed across your first four deposits — far more than the base offer without a code.

Free Spins — Which Slots Are Eligible?
Free spins are assigned to specific slot titles listed in the active promotion. In 2027, eligible games typically include titles from Pragmatic Play (Gates of Olympus, Sweet Bonanza, The Dog House), Evoplay, and BGaming. Check the Promotions section in your account after each deposit for the specific assigned title, as it may rotate between deposit tranches.
Winnings from free spins are credited as bonus funds and share the 35× wagering requirement. Spins not used within 24–72 hours of crediting expire automatically.
Casino Wagering — The Realistic Picture
The 35× casino wagering is higher than the 5× sports wagering — a factor worth knowing before choosing the casino package. On a $200 deposit with 125% bonus ($250 bonus), you need to wager $250 × 35 = $8,750 on eligible slots to clear the bonus. High-volatility slots contribute 100% toward wagering; live casino games and some table games may contribute at a lower rate or not at all. Check the specific contribution rates in the bonus terms at the time of activation.
Casino Promotions Beyond the Welcome Package
Aviator free rounds: periodic promotions with free rounds on the Aviator crash game.
Weekly cashback: up to 10% of casino losses returned every Monday, no wagering required.
Slot tournaments: leaderboard competitions with prize pools distributed to top finishers.
Reload bonus: 50% up to $200 on qualifying deposits for existing players.
Loyalty shop: redeem accumulated points for additional free spins or casino bonuses.
VIP Program for Casino Players
Regular casino activity moves you up through Mostbet's VIP tiers. Higher tiers deliver better weekly cashback rates — up to 30% at the Platinum/VIP level — as well as priority withdrawals, a birthday bonus, and access to exclusive events. Points accumulate on every casino bet regardless of the outcome.
