Jewels Blitz 3 is a quick, dense match-three: swap adjacent jewels to line up three or more, clear them, and let the cascade do the rest. Four or more in a match creates a special jewel with its own clearing pattern.
Levels come with objectives and either a move or time limit, and boosters like bombs are there for the boards that don't cooperate.
Cascades. Matching near the bottom of the board makes everything above fall into new matches automatically, which scores far more than an isolated three-match.
Bombs and similar boosters clear areas of the board directly, which is what saves a level that has stalled.
Yes — swipe to swap. Nothing to install.
