Welcome bonus at Casino Tropez is 100% bonus, without anything extra on top of that. But there is a hint, if you register account and then just open live chat before depositing and claiming bonus, you could ask live chat agents to offer you something extra. For me they give me 200% instead of 100%. Wagering requirements for welcome bonus are 30 x bonus, bonus is cashable which is great for Playtech casino.
I claimed welcome bonus from Casino Tropez with 25$ deposit, and casino gave me 50$ as bonus money, as live chat agent promised to me. So if you want to try to ask some better welcome bonus it will never hurt you, just open live chat and try, nothing bad happens.
With 75$ on my balance I start playing Marvel games, in past I was addicted to this games and play it often. First game was Iron man, played it a bit, but after couple of losing spins in a row without any payout I just left. By the way I usually use this thing at slots- when I see 4 or 5 losing spins in a row without any payout, sometimes I leave this game, just because usually it is bad sign. Or probably that all just in my head. Next game that I opened was Archer, with 0.50 bets, lost there quite a lot money, and was left with 10$ only. With such low money left I decided that I try great blue at 0.25 bets, just in case it hot and will give freespins fast. But such event not happens and I am just lost my money.
Bonus is average, not so good, but you could try to ask live chat to increase it.
