I don't like the game at all. Tried with the super stake first and find it wortless. Features paid between 0 and 10x. In 500 spins got 2 bonus, 14 and 23x. Base game is totally dead as well.
However first bonus buy (5 spin) got +7 spin extra spin. Built it up and hit this beauty.
Overall badly balanced slot. Getting bored before realized the potenzial.
overall: 3/10
