The game offer free spins feature which is trigger by at least three scatters. The name of this feature is Carnival Attraction free spins. Here, before the start you have to pick out one of three different feature. You can choose between 5 free spins at x10, 10 free spins at x5 or 15 free spins at x3 multiplier. Last time when I played Carnival Royale, when I triggered the feature for first time I selected the feature with highest multiplier. It is really huge at x10. I expected big win here, but at the end only x 20 bet. At second feature I selected free spins with x5 multiplier and the winnings were lower than first time.
I think free spins feature is good. You can choose any of those 3 feature which I think is great. And I believe that sometimes it could provide big winnings.
Base game is interesting enough and during my gameplay sessions I had decent winnings. I never won bonus game with balloons. Here you have to pick out some balloons and some of them will reveal coins wins, some others will end the bonus game. But I like, prefer to play free spins more than bonus games.
After all I think this game is good enough and I could play it sometimes, maybe even more often in near future. I had nice time while I was playing it and I think it could provide good wins. The graphics are good.
