Screw Workshop

How to play

Select a screw, then choose a glowing empty hole. A plate drops as soon as all of its supporting holes are empty. Clear every plate before the displayed move limit; otherwise the attempt ends.

Check which plates share a screw before moving it. Keep enough genuinely empty buffer holes for later screws, especially when layers overlap or a fastener is locked. The six chapters introduce first moves, overlapping plates, shared fasteners, locks, tight routes, and mixed layouts.

Undo restores the previous full move. Hint highlights a safe screw and hole but does not move them. Restart resets the puzzle; cleared puzzles can be replayed to improve your stars and best move count.

Screw Workshop: Game guide

Touch, mouse, and keyboard are supported. Cleared puzzles, unlocks, and best moves are stored in this browser when local storage is available. There is no account or cloud save; an unfinished board may not survive a reload.

Parent note: This non-diagnostic logic puzzle asks players to plan moves, notice support relationships, and revise a plan. Play is self-paced, with no countdown timer. The displayed move limit is part of each puzzle.

Frequently asked questions

What is the goal?

Move screws into open holes until every wooden plate loses all of its supports, staying within the shown move limit.

Why did a plate fall?

It falls immediately when no screw remains in any of its supporting holes. A screw shared by overlapping plates can support more than one plate.

Does Hint make a move?

No. It highlights a safe screw and destination hole. You choose whether to make that move; Undo can reverse a completed move.

What happens when I reach the move limit?

The attempt fails if any plate remains. Restart the puzzle and plan buffer holes before moving screws.

Where is my progress saved?

When browser storage is available, cleared puzzles, unlocks, and best moves stay in this browser. They are not uploaded or synced to an account.
