After downloading their software and sign up, I made the 1€ deposit via my Mastercard. I saw the promo in my promotion page too so I knew it still would be available. After 5 minutes I still didn't have the bonus so I wrote to their live support. They told me that everything was fine and that I should wait another 5 minutes to get the bonus added automatically. Right after my conversation, the bonus was already there. So from my 1€ deposit I got 21€ bonus and my balance was 22€. Well that's really nice from such a small investment. Besides, the wagering was only 30x which is really not that much.
I played only Game of Thrones, 15 payline version. I stated with 0.15€ bets per spin, got few features and after an hour of playing my balance was already 80€. I continued to play this slot, varied my bets from 0.15€ to 0.30€ and then I got free spins again, I chose the Lannister spins which are 10 spins with 4x multiplier, in the last spin I got all Lannister wilds and it paid me 450€! After that I continued to play this game for some time to finish the wagering, which I later did. I did contact the support a few times to ask, how am I doing with wagering and the support was really great too.
After meeting the wagering, I made a withdrawal of 380€. Oh, I forgot to add the amazing thing for this bonus- there is no max cashout! So I was able to withdraw all my balance. This casino is really nice, the support is great and the game selection is large, so this bonus is a must try!
