For now I only play online, I was once or twice scheduled to go to the Casino with a colleague, but I never got there. My colleague had explained a few times how good it was, the sounds were bright, everything was lit up, he said that you could win more there, but I don't think that was the case, and I don't think I'll go to the Casino, I've had enough of online slots.
NolimitCity is a good provider for me, I have already hit 10,000 times, of course, on a bet of €0.10, I bought some kind of bonus 2-3 per game, it can hit anything, games Tombstone and r.i.p. version, Fire in the Hole 3, Crayz ex Girlfriend, Mental
There were good casinos with a 500% bonus, of course I can't find them anymore, I don't know, it's hard for me to finish the wagering bonus, I get tired of placing a big bet and in the end I lose the bonus and the money, you can have a lot of will and time to turn it around on low bets.
When I hit a big €1000, it hasn't happened in a long time, but sometimes I withdraw everything, sometimes a lot and end up with nothing or I get back a little more than €1000
Play Casinos that pay out quickly for me Bitstarz, Winz, bet365, Casinos where you have to wait a long time for a payout, just avoid the problems. But to win you need luck!
I've never liked buying bonuses, I bought some bonuses on Sweet Bonanza 1000 for €20 and I think once I landed the 1000x multiplier hit €200 the rest was a waste of money!
