I don't mind that so much when it comes to reloads, but I do like to at least get a decent one off welcome bonus when I first join a casino and casinos such as videoslots that send out free spins with no wagering receive plenty of my business in return as well. Most of the time 10 free spins on any game will only pay out a few pennies, why bother attaching a wagering requirement to that?
At Whitebet the wagering for this initial welcome bonus is set at 25x the bonus plus deposit amount which is at best merely reasonable. Free spins receive their own 40x wagering too, so if you do take this bonus I recommend definitely waiting until you have finished playing with your deposit and bonus before trying your luck with the 40 free spins.
About those, The Wish Master seems a very strange choice of game to give away free spins on, primarily because if you are party way through a feature when the 40 spins run out you will lose the rest of your spins with the feature activated even if you do have a cash balance or are willing to make a deposit. That's just the way this specific game works - even when the feature is active you still have to pay for your spins. It's a setup that no doubt works for the casino but definitely isn't very player friendly.
One thing I will say is that Whitebet offer a very nice poker bonus policy, up to $2000 in free money can be earn if you spend a lot of time at the tables. That's definitely a more attractive deal than this casino welcome bonus!
