Overall Rating

7.8
Spinomenal made an excellent job designing this game. In general, this slot has a great aesthetic and offers players a strong gaming experience. The graphics and animations are of the highest quality, but the winning potential is somewhat low. This video slot has quite a lot of bonus features but, in fact, it is just a simplified version of the original Spinomenal game which imight seem to be more appealing to some players.
