Instead of making the minimum deposit for this bonus, after the sign up I made a 20€ deposit and received 20€ bonus. And playing with 40€ balance the wagering would be 800€ which is not bad at all. I started to play Bloodsuckers. I played it with 0.50€ bets and played it for about 200 spins. Within them I got few bonus rounds with not more than 5€ wins, and once free spins, but they gave me only 11€ and few cents and I was kind of upset because with 0.50€ bets I was expecting more. (although I think we're always expecting more).
Then I switched this game for Jack Hammer and I had a really great time with it. I played it with 0.50€ bets and my balance was really going up, I had many sticky wins which even gave a few times 15€. Later, with my last spins I triggered free spins and since I got 7 spins symbols, it gave me 20 free games with 3x multiplier. They helped me to boost balance for 30€. Then I made the famous mistake of increasing my bets to 1€ per spin and eventually it emptied my wallet completely.
I think this is a great bonus, because the wagering isn't enormous (If I continued to play with smaller bets it's quite possible I would meet the wagering and made a cashout) and the minimum deposit for this is only 10€ (And with that you'll start playing with nice balance of 20€). So it's a great chance to try casino and play great games from Microgaming and Netent, besides the variety of games is nice. Definitely recommend!
