I made a 20€ deposit and received 30€ bonus which I was very happy about. I had 50€ bankroll and wagering of 1500€ to meet. I went to play Spinata Grande. I played with 0.40€ bets, very soon I received tornado feature, but I collected only 5 symbols and won 1€. I got another tornado feature 10 minutes later and it paid 20 x bet win. I played for about half an hour but I couldn't increase my balance and when it was down to 20€, I went to have a little fun with Twin Spin. I had only few euros left when I had a big win of 13€. Soon another big win of 10.80€ came and my balance was now over 20€.I played around 400 spins with minimum bets after that, I had few big wins again, but none of them were close to 100 x, my balance decreased til I lost all money.
Overall I think this is a very good bonus and is worth trying. Game selection is great and even though games take long to load, when they do, they didn't lag at all. In my session I wrote an email inquiry to support with a question about the bonus terms and the support answered my email within 15 minutes, however, the answer was just their terms copied, without any explanation to my question and I find that a bit rude so my only criticism goes to Maxxx casino support. Bonus itself I would rate with 8/10 just because the wagering requirements could be lower.
