For a first deposit Jetbull casino offers to players 100% bonus. Wagering requirements here is hard to beat - 30x deposit + bonus, which actually make it 60x bonus amount received.
I claimed this bonus with 30 euros deposit, and 30 euros bonus was credited to my account instantly, without any hassles. Wagering requirements was 1800, with 60 euros starting balance it is possible to make this WR, but of course you need a lot of luck to beat this one, and a lot of big wins for sure.
I decide to start playing with Jack hammer slot. I can't say that I regular playing this game, but this time I decide that I want to play this game a bit. I make starting bet 0.50, I think Jack hammer is not such monster like DOA for example, which can kill you fast if you make big bets. After wagered about 100 spins I finally hit 10 free spins, but nothing good happens, and with 40 euros or so left at my balance I decide that this is time for Dead or alive. My bet size was 0.27, with such balance this bet size give good chances to see free games at least ones, and this means that at least once you have a chance to a huge payout. This time I saw free games 4 times, it is good result. Unfortunately no good wild landings, no any good payouts, and I am finished with zero in my account.
Overall it is regular online casino bonus, but wagering requirements is a bit higher than usual, so if you have few other bonuses with lower WR waiting for you - you better left this one for an older times, when you will not have any other options.
