Block Puzzle Star
Block Puzzle Star is chain-clearing with fireworks: tap groups of three or more same-coloured stars to pop them, and engineer big enough clusters to earn the star bombs that clear what clustering can't.
Score scales steeply with group size, so restraint — letting colours pool before popping — is the counterintuitive engine.
Tip: pop small groups only to merge big ones; a 12-star clear outscores four 3-star clears several times over. The jewel games tag sparkles on.
