Bubble Crush

Bubble Crush is a tap-to-pop puzzle about finding the biggest cluster on the board. Groups of two or more same-coloured bubbles vanish with one tap, and clearing large groups at once scores far more than picking at small ones, so patience and board scanning beat fast fingers. When a column empties, the rest slides sideways, opening fresh arrangements and chain opportunities. Levels set score targets and limited moves, and later boards add stone bubbles that only special clears remove. It is easy to learn in ten seconds and hard to put down for ten minutes.
