The bonus can be claimed in the cashier prior depositing and I had a hard time finding it as the only bonuses I saw there was for sports bets. They don't have live support so I wrote an email describing my situation and surprisingly received answer within 5 minutes. I followed the directions from email and found the bonus so after I made the minimum deposit of 10€, I received the bonus right away. I thought that the wager was 50x bonus which is still quite a lot, but when I checked cashier wager and I was stunned having 20€ balance I had to rollover 1000€ which meant that bonus had 50x deposit+bonus wager. It was my mistake that I didn't pay enough attention to this, otherwise I wouldn't have claimed this offer.
Then I went to play Immortal Romance with minimum stakes, hoping for a miracle to meet the wager. Instead I had an absolutely dry run, only once I had a 10x bet win, otherwise I had only dead spins and ran out of balance within a little over 100 spins.
Overall I would strongly recommend to not take this bonus. The game selection is very good and even though support is via email, they respond fast, however the bonus has ridiculously high wager and I would rather recommend to play bonus free. I give this promotion 4/10.
