Spin Lock: Safe Cracker Puzzle

A gem is locked at the heart of a vault. Spin the brass dials until every gap lines up into one straight channel, and watch it shoot free with a clunk, a flash and a chime.

Calm, tactile puzzling
Every dial clicks as it turns, snaps into place when you let go, and glows when its gaps line up with a neighbour. No timers, no lives, no rush: just you, the vault and that satisfying final click.

A real challenge for sharp minds
Every level has a par, the fewest moves possible, worked out by a solver. Solve it in par for three stars. Free undo and restart mean you can always try for a cleaner solve.

Five vaults, 150 puzzles, new tricks in each
• Bank Vault: learn the dials, then meet the gears that link two dials together.
• Pirate Chest: one-way ratchets that only turn the way their arrows point.
• Clockwork Tower: latches that won't budge until the dial inside lines up a gap.
• Sky Observatory: every trick at once, under the stars.
• Dragon Hoard: two gems, two channels, and the hardest locks in the game.

Every solved puzzle drops a gem into your Gem Gallery: 150 hand-cut gems in ten cuts and fifteen colours, plus five showcase treasures for clearing a whole vault.
