Just wanted to clarify that it was free bonus without any need for deposit. I didn't deposit anything, just got "free" money from casino to play any game I like, but without possibility for withdrawal until I make 35x wagering with it. I got bonuses like that few times but I never never managed to get even close to 35x wagering.
How much money do you receive on this bonus? Cash or free spin? And can you wager it to any games or just specific games such as slot games?
It’s not impossible to claim this bonus but also it’s not easy to complete the wagering requirements using only the bonus amount that you received from the casino since you have small roof for absolute bust probability.
Anyway, if you keep getting this bonus without deposit I think there’s no harm on keeping trying on games that gives a balance volatility and hit ratio since your goal is to accumulate wager without busting your bankroll.
