The bonus money received as part of the 1Win offer can be spent for betting on sports. If there is not enough money in your main account, the bonus balance is used for betting.
Another 1win online casino bonus is 30% cashback of up to 74,000 KES. To claim this prize, you just have to play the slot machines. At the end of the week you will receive a refund based on the amount of lost bets. The cashback does not require a deposit, so you can withdraw the time or use it to play again.
