Personal testers opinion

At this online slot, Microgaming tested the concept of expanding symbols, when the first reel was filled. Ariana slot machine positively often gives out the bonuses with an average winning of 30x bets in there, and 157x in the usual spins. You should follow the mood of the slot with the help of the third scatter symbol. If you see two scatter symbols in a row without the third, or if several empty bonus games are triggered, then this will be a serious argument in favour of changing the slot.

The idea with expanding symbols has its continuation at Pretty Kitty slot.  The chances to trigger the bonus feature are equal to 0,77%, which means, following the statistic it should be reached in every 129th spin. Middle recommendation about fulfilling the bonus requirement; wagering - 5,47 out of 10.
