How to play
- Goal
- Turn the fixed mirrors until the light touches every rune mirror exactly once and enters the exit gate.
- How it ends
- The vault opens when the beam lights every rune mirror and reaches the gate; a vault cannot be lost.
- Record
- Each vault keeps the fastest first solve and the fewest rotations as separate public records with their holders' names.
- A bright source sends a beam through the vault. Every silver dial is a rune mirror. The beam bends 90° at a mirror, crosses empty floor freely, and must visit every rune mirror exactly once before entering the iris gate. A wall, an early gate or a repeated mirror stops the route.
- Tap a mirror to switch between the two diagonal faces. The live beam and lit-rune count show the result at once. In the worked picture from Vault 001, turning the first reached mirror sends the beam to the second rune instead of the wall. Trace the next fork the same way.
- The gate opens automatically on a complete route. Undo and Reset keep every counted rotation and do not restart the first clock. Only the first solve counts for time; a replay can improve rotations. Open a vault from this page to use public records.

All 160 fixed charts have one independently verified answer and a locally forced deduction trace. Private witnesses do not ship. Saves use morass.mirror-vault.v1; sound follows the shared arcade setting. No ads or analytics run inside the game.
About Mirror Vault
In a buried moon observatory, silver mirror dials carry one pale beam across a stone vault. Turn them to wake every rune and release the brass iris gate.
The 160 fixed vaults grow from short 4×4 paths to winding 7×7 routes. Each has one independently proved answer and a visible turn-by-turn deduction route.
A vault cannot be lost. Your first solve fixes its time; a practice replay can still improve the separate fewest-rotations record.
