Bolt Puzzle

Bolt Puzzle is a cozy 3D puzzle game about unscrewing, sorting, and gentle repair work.

Twist bolts out of layered boards and clear them by color. Every bolt you free makes the board lighter — clear all the bolts holding a plate and it falls away, unlocking what's hidden underneath. The tray only holds five slots, so the real puzzle is the order you choose.

Between boards, the workshop is waiting: four broken wind-up toys — Pip, Milo, Aster and Tovi — need your help. Repair them one stage at a time, up close: open service hatches, put parts back where they belong, and watch each toy come to life on your collection shelf.

Core features

• 84 hand-tuned levels, every board verified solvable
• Layered boards: unscrew a layer's bolts and its plate falls away
• A 5-slot color tray — plan your order or you'll jam
• 4 wind-up toys to repair across 12 close-up stages, with a collection shelf
• Cozy low-poly 3D look and soft synthesized sound effects
• Progress saves automatically in your browser

How to play

• Click a bolt to unscrew it — it flies into the tray.
• Complete a color set in the tray to clear it.
• The tray holds 5 bolts; if it fills without a complete set, you're jammed — undo a move or restart the level.
• Bolts hold plates in place; free them all and the plate drops.
• Repair stages play like the puzzles, up close — clear them and the toy mends itself.

Controls

Mouse — click to unscrew. Everything else is on-screen buttons.
