PRISM RELAY

Route one laser through a maze of rotating mirrors. Every generated stage has a verified solution; decoy mirrors invite false turns. Tap or press Enter on a tile to rotate it. Solve 150 progressively denser boards, with undo, hints and saved progress.

◉ = emitter◎ = receiver╱ ╲ = mirrors★ = solved

Rotate mirrors to guide the beam into the green receiver.

Mission Console

Each blue tile contains a rotating slash or backslash mirror. Yellow light travels along rows or columns and reflects when it hits a mirror. Reach the green receiver without escaping the grid.

Keyboard: Tab through mirror buttons and press Enter or Space to rotate. Every solved stage unlocks the next and saves locally; the game needs no login. Hint uses one of three charges per stage.

Scoring

Earn 3 stars for solving in few moves without hints, 2 for a longer solution and 1 after heavy assistance. Stars are feedback rather than paid currency.

A procedural puzzle can still repeat a pattern; these 150 stages are deterministic and mechanically solvable, not claims of 150 hand-designed unique layouts. Reduced-motion friendly, with accessible button controls.
