After about 12 hours I received an email from the casino support in which they have confirmed that I have joined on their casino just through AG.
This is not a bad offer. First of all, the bonus is cashable unlike some other bonuses from the iNetBet offer. The wagering requirements are 25 x deposit + bonus. Allowed games with which you can fulfill the wagering requirements are only the slot and keno games. I also like that the casino did not protect itself by restricting the maximum bet or the amount of the maximum cash-outs. I have made a deposit of 25 euros via Neteller and I had 50 euros for a game. I was not lucky enough to make a good result and to request a withdrawal. But I spent almost 2 hours playing only 3 slots. Those were my favorite RTG slot games: Aladdin's Wishes, T-Rex and Pay Dirt. Definitely it was not my happiest day. The only win bigger than 100 x bet I've had playing on Aladdin’s Wishes. In fact, on my bet of 0.4 Euro per spin in 25 free spins I won almost 90 euros. However, in my opinion this offer deserves a positive rating and it is likely that I will also use this bonus the next month. For this offer I give 6 out of 10 possible stars.
