The casino is powered by multiple great game providers including Netent, Big Time Gaming, Play'n Go as well as many others, and for your second deposit you can get a 50% match bonus. Generally I'm not a fan of 50% bonuses, but good bonuses lately are difficult to find and this one allowed to have an extra playtime besides I look at it more as a second chance bonus as you start wagering only after you've lost your real money, until then you can withdraw your winnings at any time.
In order to receive this bonus you need to make a deposit of at least 10eur and use the second deposit bonus code. I made a deposit of 20eur using the code and got a 10eur bonus. The bonus had wagering of 400eur so I started off my session with Starburst, hoping to boost my balance a little bit. I played a few hundreds of spins, had some ups and downs but I never managed to get over 40eur balance. When eventually my balance dropped to 15eur, I went to Reactoonz. I played with minimum bets and quickly enough managed to get Gargantoonz feature but unfortunately it paid little under 100x bet. I stuck with the game for a while but I didn't manage to get any other decent wins and eventually I ran out of balance soon.
Overall I had a nice session at Casoola casino, I enjoy their game selection and the bonuses have good wagering, besides you can always withdraw your real cash. It's not the best bonus I've seen, but it's a pretty decent one for second deposit.
