    • The cashback has a 15x wagering requirement before it can be withdrawn.
    Bonus Verdict

    This welcome bundle gives you a balanced mix of bonus cash, spins, and cashback. The low minimum deposit of €10 makes it accessible, and the wagering on the bonus and winnings from spins (30x) is reasonable compared to industry standards. The 5x max cashout from the bonus is a downside for high rollers, and the cashback wagering (15x) is something to keep in mind.

    Bonus Verdict

    The iBet Casino welcome offer gives new registered players a welcome bonus of 100% up to €100 on their first deposit of €10. It must be claimed within 30 days of registration, which we think is a long enough time to reach the 50x rollover requirement. The bonus can be accessed through the Rewards section or by stopping by the cashier.
