I was not sure what was the minimum deposit so I can claim that offer so I contacted their live support, my opinion for live support, they need to be a bit faster, for my taste they are a bit slow, with responding in the live chat, so yes he confirmed me that the minimum deposit I had to make was 10 euros to get those 50 free spins and the additional was 12 free spins on Twin Spin slot.
A bit confusing, because the wagering of the free spins, what they are giving for every deposit made is X 50 and for those 50 free spins promo I got, the wagering was a bit lower, X 35, but ok I guess that's the rules of the promo. From those 12 free spins on Twin Spin I got only 0.50 euros and from the free spins I choose Jack and The Beanstalk, although I have no luck on it, so I won around 17.50 euros. So I was having 28 euros to play.
I played Jack and The Beanstalk, maybe for 150 spins, but nothing was happening except that I lost half of the money. Then I switched the game and played Jack Hammer 2, but didn't trigger the free spins and played with the minimum bet of 0.50 euros per spin and lost it all. Well even if I lost I had good time for an hour or so and will be depositing here again.
