Read the slots
Write down the number shown on every disc before forcing the lock.
Free in-browser puzzle tool
Enter the slot shown under each lock disc, record how the other discs react when one disc moves right, and calculate a shortest route that places every disc on slot 4. Nothing is uploaded or saved.
Count the moving discs in the chest lock. The solver supports two through seven discs.
Use the visible number under the fixed marker for each disc. Valid positions are 1 to 7; the solved center is 4.
Each row is the disc you move right. Choose +1 if a target number rises, -1 if it falls, or 0 if it does not move.
Write down the number shown on every disc before forcing the lock.
Move one disc right once, record which discs rise or fall, then undo it.
Enter the observed map and follow the generated sequence from top to bottom.
Lock layouts can differ by chest and save state. This tool models the lock you are actually looking at instead of relying on an incomplete fixed list.
The search runs entirely in your browser and checks valid states until every disc reaches slot 4. It prioritizes the fewest moves for the map you entered.
Do not guess a connection from the artwork. Record whether the number under the fixed marker rises, falls or stays still.
When a result is impossible, rebuild the matrix from one-move tests. The most common error is reversing +1 and -1 for one linked disc.
