This Clustered slot based on a 5x5 grid must be one of the hardest slots to trigger features with low payouts and a lot of empty dead spins. On the reels, you will find musical instruments, followed by the band members which are the higher paying symbol. The game does not have a standard wild, however, one can be created by producing winning combinations which will increase the chances of winning more. During the base game, there is a multiplier that increases as you create more winning combinations.
There is a concert feature that can be triggered by getting 4 – 6 member symbols in a winning combination. During this feature, a special round is produced with all the members adding their special effects to the round, for a chance to clear the grid to trigger free spins. If you know the "Trinity" feature on Moon Princess, then you should know how this plays out. Just remember during this concert round the payout is awful, but on other cluster-based slots, with this gameplay, it pays much better. I get paid x2 – 7x my total stake and that is disappointing.
You need to clear the grid to trigger 8 free spins. The member active during the base game while triggering free spins will add special effects on free spins.
During free spins, there is an increasing multiplier that is sticky and resets to the free spins trigger multiplier on every spin. If you managed to get 4 – 6 member symbols you will get 2 additional spins and a free spins round with all member special effects. You can re-trigger up to 20 free spins.
As much as I hate losing on this slot I just go back for more. I think what keeps bringing me back to this slot is the challenge of beating it one day. I had a couple of x100 and 150x wins, but I want to see x500 plus like I always do on Moon Princess or Rise of Olympus.
