Usually, when I see a 200% welcome offer I think it is pretty generous, but it isn't often when a casino gives a welcome bonus worth of 300%. The requirements for it was quite friendly- 20x wagering of deposit + bonus. The minimum deposit was 20$ and maximu cashout 6x bonus. Of course you can always wish for a lower wagering like 20x deposit would be amazing or if there wouldn't be a max cashout.
Anyways, after I signed up I had a small talk with their live chat that confirmed my eligibility for this bonus. Then I made the minimum deposit and had 60$ bonus. Altogether my balance was 80$ with 1600$ wagering. Although I asked, if all slots complete wagering 100% and got a positive answer, I checked their terms anyways, and there are few important things about this bonus. You can play only slots. Other games not only "doesn't count" for the wagering but makes all your winnings void. Second, you cannot place bets higher than 20% of your real money balance. After reading this I contacted the support again and they told me, that in my case I made a 20$ deposit so my bets cannot exceed 4$. Chat told me that it is for the first 2 welcome bonuses, after that there are no limits.
I spent a lot of time playing Dr Jekyll and Mr Hyde slot. At first I placed 0.60$ bets for around 140 spins, when I got free spins feature. Then I doubled my bets and played 100 spins more, I lost a lot and fast. At the end I got free spins round again, but it paid me only 13$. Then I visited Gladiator slot. I played for 20 minutes I guess, had a few wins 3x bet size or a bit more but eventually lost all.
Overall I think this bonus is good for Betsoft game lovers. I am not one of them so the time I spent there wasn't very exciting, however, I wouldn't make a deposit that big at their casino, but with this bonus I finally got to play Dr Jekyll and Mr Hyde free spins. Otherwise I always go bust before I get that far. The offer is decent and the play through isn't too big too and the support is very nice. But read the terms carefully to not break their rules and void your winnings.
