Chain Toggle

Chain Toggle is a logic puzzle where every tap changes more than one tile. Tap a tile to toggle its state together with the four adjacent tiles above, below, left, and right.

Study the board before each move and plan how one change will affect the surrounding pattern. Your goal is to turn every tile on before you use all available moves.

Each puzzle gives you a limited move count, so the order of your taps matters. Work through the chain reactions, correct dark tiles, and find a sequence that lights the entire grid.
