Puzzle Lock

Puzzle Lock is a hand-crafted sliding block puzzle. Every chest is locked by a 6x6 mechanism of bronze sliders: horizontal blocks only slide sideways, vertical blocks only slide up and down, and every block blocks the others. Your job is to drag the pieces around, one smooth slide at a time, until the golden key block reaches the glowing keyhole on the right edge.

- 24 BFS-verified levels, from gentle 4-move warm-ups to brutal 30-move master locks
- Snap-to-cell sliding with fling inertia, click feedback and spark effects
- Padlocked blocks: slide the guard block off its home cell to release the lock
- Twin blocks: two matching pieces that always slide together
- Earn up to three stars per level by solving near the best possible move count
- Coins buy hint packs, undo charges, skip tokens and the Obsidian theme
- Built-in move solver powers hints, so every hint is provably strong
- No ads, no accounts, offline play, progress saved on your device

Think ahead, slide smart, and crack every lock in the vault.
