How do bonuses work at Gran Sino?

We believe in transparency, especially when it comes to bonuses. Our offers are designed to give you more playtime on your favorite online slots, but they always come with certain rules. Here is a clear overview of how our bonus system works.

Depositing and Activating

You can easily activate a bonus while making a deposit via the cashier. Choose the desired bonus from the dropdown menu before completing the transaction. Most regular offers, including the welcome bonus, require a minimum deposit of €20. Specific offers, like the weekly reload with free spins, may require a higher minimum amount.

Wagering Requirements

Almost all casino bonuses are subject to wagering requirements. At Gran Sino, we generally apply a wagering requirement of 35 times the sum of your deposit plus the bonus amount. Winnings from free spins have a separate requirement of 40 times. You can always track your wagering progress live in your account. Once the conditions are met, your bonus balance is converted to real, withdrawable cash.

Game Contributions and Limits

Please note that not all games contribute equally to wagering your bonus. Slots generally count for 100% (with some exceptions listed in the terms), while table games and the live casino often count for 10% or not at all for regular bonuses. There is also a maximum bet limit per spin while playing with bonus money, standardly set at €5.

Looking for more ongoing rewards without wagering requirements? Check out our exclusive VIP program, where we reward loyal players with real cash bonuses, higher withdrawal limits, and personal account managers.
