OVOCasino is pretty new.
Good people behind it - I'd definitely say you can trust it.

Sorry to bump this thread guys but I was looking for some threads about Novomatic slots powered by Greentube.
I play those slots now for a good few years,at first at Stargames and more recently at Quasargaming (same folks as OVO casino).

I just wanted to state that the people behind for example Quasargaming are good folks and their CS is just very very good.
Quick replies on queries,
fast payouts and if you play more often you get a VIP manager assigned.

All your questions or issues will be dealt with in a fast and swiftly manner.
I spoke to a few people from Quasar in person and they are just very nice people.
BUT - I do have to agree with some comments above that Novomatic slots are very high variant slots but hey,the payouts on bonusfeatures can be very very rewarding as many games like Book of Ra - Lucky Lady's Charm - Dolphins Pearl have huge chances of retriggering the bonus.
Also you can hit a bonus within a few spins,just luck of the draw.
Sometimes you end up with like 100 free spins on those machines and on an average bet of €1.00-€2.00 per spin like I do on those games the return can be amazing.
Don't get me wrong,if you pick the wrong machine it can dry up your bankroll very quickly but that counts for all slots.
I have a few screenies left from recent wins,just to show that wins are possible just like on any other casino who offer Netent or MG or whatever brand of slots.
Any questions about Novomatic slots,you can always ask me as I know them ALL inside and out...
Mark.
