At first I had a conversation with their live help to see if they accepted players from my country and if I could play with bonuses, as my country very often is restricted. The help was really friendly and supportive and assured me that I was more than welcomed to play there and use bonuses.
I have to say that claiming the bonus wasn't that easy. I made a 25€ deposit and I had to verify my account not only be email but also by phone. After I had made my deposit, the bonus wasn't in my account and I had to claim it in my account bonus section. And not only I had 25€ match bonus in this deal, but they also give 1 free spin for every 5€ deposited so I had 5 free spins on Gonzo's Quest slot.
With 50€ balance I went to play Twin Spin slot. I had to wager little less than 900€ but still I sticked with minimum bets only. I had a few really nice winnings and after a few hours of playing, I had 100€ withdrawable balance. Then I also went to play my free spins but didn't win anything from them. I requested a withdrawal to skrill and received it the next day without any verification.
Overall I had a really nice time at Riobet and this is a great bonus as it not only gives good match amount with friendly wagering, but also the variety of games to play is really nice.
