About

A match-three puzzle with six differently shaped gems, so colours stay readable even on washed-out screens. Gems animate as they swap and fall, cascades multiply your score, invalid swaps bounce back, a hint glows if you hesitate and the board reshuffles itself when no moves remain. Play 30 Moves for strategy or 90 Seconds for speed.

Objective: Score as many points as possible within 30 moves or 90 seconds.

Modes: 30 Moves, 90 Seconds
