Your objective
Open each chest, collect its ore nuggets and occasional lockpicks, then face the next, harder lock. The run ends when no lockpicks remain.

How to play
Turn the tumblers until every pin—the moving point on a tumbler—reaches its marked target.
Tumblers and pins
Select a tumbler and turn it left or right. A turn moves its pin and can also move pins on connected tumblers, sometimes in the opposite direction, so watch the whole lock before committing.
Opening a chest
- 01Select a tumbler by clicking or tapping it.
- 02Turn it left or right with the visible controls, A/D, or the Left/Right Arrow keys.
- 03Watch how its pin—and pins on connected tumblers—move toward or away from their targets.
- 04Place every pin on its target to open the chest.
- 05Claim the reward and continue to the next, harder lock.
Lockpicks and invalid moves
- A move is invalid if it would push any affected pin outside its allowed range.
- An invalid move changes no pin positions and damages the current lockpick.
- A lockpick breaks after exactly 3 invalid moves.
- A broken lockpick does not reset the lock or its pin positions.
- Manual reset restores the current lock’s starting layout.
- When the last lockpick breaks, the run ends.
