Slide symbols to make clusters of like-clusters. Clusters will score and symbols will be refreshed perhaps triggering a cascade effect.
Totally free. No in-app purchases.
If your move does not make a scoring cluster you lose one Move. The game ends when you run out of Moves.
Bonus Moves and bonus jokers (wild) are awarded for scoring clusters of large enough size.
A cluster is a set where each element in the set is adjacent to a least one other element in the set.
