Additional Information
How To Get The Bonus
- Sign Up or Log In to Your Account
- Choose your preferred bonus before depositing
- Make your qualifying deposit
- Complete the wagering requirements within the bonus validity period
Terms and Conditions
- You must choose either the casino bonus or the sports bonus during sign-up, in the cashier, or on the Bonuses page before depositing; once you pick one, you forfeit the other, and the choice can’t be changed after the deposit.
- First deposit can qualify for 125% (if made within 30 minutes of registration) or 100% (if made within 7 days); minimum deposit is €/$ 10 for the bonus-only version and €/$ 20 for the bonus + free spins/free bets versions; maximum bonus per deposit is €/$ 1000 or €/$ 2000 depending on the selected option.
- Bonus funds and free spins/free bets are credited to the bonus balance and may take up to 72 hours to be added after a qualifying deposit.
- Casino bonus wagering is x35 of the bonus amount and must be completed within 72 hours; eligible sections include Casino, Live Casino, and Virtual Sports, but contribution can be reduced (example given: Live Casino and Virtual Sports count 10% of stake).
- Sports bonus wagering requires accumulator (express) bets totaling x5 the bonus within 30 days; the accumulator must include at least 3 events, each with minimum odds of 1.4 (and some deposit-stage summaries also list 1.8), with no stated maximum number of events.
- Winnings from free spins / crash-game free bets are credited to a separate bonus account and must be wagered x40 within 72 hours (rules section) and/or within 3 days for activation + 3 days for wagering (offer summary), depending on how the specific FS/FB bonus is issued.
- If you have real and bonus balances, bets are taken from real money first; bonus funds are only used once the real balance reaches zero.
- Withdrawals only apply to real cash; withdrawing (or attempting to withdraw) while a bonus is active can void the bonus balance and is treated as leaving the promotion unless you stay within the rule that withdrawals can’t exceed wagered deposits and you keep at least double the bonus face value on the gaming balance.
- The operator may set max/min bet limits while a bonus is active; breaking these limits can cancel bets and may void bonus eligibility or winnings.
- Bonus is limited to one per player/account and also restricted by household, address, phone number, shared device/computer, and shared IP; country-based eligibility restrictions may apply.
- “Risk-free bets” and similar bonus mechanics do not count toward wagering.
- Bets settled after the validity window (30 days sports / 72 hours casino) do not count; all bets must be settled before the bonus validity ends.
- The operator can cap winnings from bonus funds, change/withdraw bonuses, restrict offers by country, and refuse/close accounts or void winnings in cases of suspected abuse, fraud, or money laundering.
- General terms and conditions apply.
