| Nuts & Bolts: Screwing Puzzle

Nuts & Bolts: Screwing Puzzle is a timed mechanical puzzle game where you rearrange screws between available holes to release secured plates. Select a screw, move it to an empty hole, and use the resulting physics to make plates fall away. Clear every plate before the three-minute level timer expires to advance.

The primary objective is to remove every plate from the puzzle board. Players do this by moving screws into empty holes so that plates lose their support and eventually fall from the play area.

Nuts & Bolts: Screwing Puzzle challenges you to free a series of wooden and blue mechanical plates by repositioning their screws. Each level begins with a collection of plates held in place by screws and a set of available holes. Click or tap a screw to select it, then click or tap an empty hole to move the screw there. When a plate has fewer than two supporting screws, its physical state changes: with no supporting screws it falls, while one remaining screw allows it to swing.

You have a three-minute timer for each level, so planning screw movements is important. The interface also provides an Undo button, a screw-removal action, a plate-clearing action, and an extra-hole action. Completing a level awards gems and advances the level number. Progress is saved locally, allowing your current level and gem count to persist.

How to Play

1. Select PLAY from the opening menu to start the current level.
2. Examine the plates, screws, and available empty holes on the game board.
3. Click or tap a screw to select it.
4. Click or tap an empty hole to move the selected screw into that position.
5. Watch how the plate reacts after its supporting screws are moved.
6. Use Undo when you need to restore the previous move.
7. Use the available action buttons when necessary to remove a screw, clear a plate, or add an empty hole.
8. Continue rearranging the screws until every plate has fallen away.
9. Complete the board before the 3:00 timer reaches zero.
10. After success, the game awards gems, increases the level number, and presents the NEXT LEVEL option.
11. If time expires, the game shows Time's Up! and provides a RETRY option.

Winning & Losing Conditions

Winning Condition

A level is completed when all plates have been removed from the game board.

Losing Condition

The player loses when the level timer reaches zero. The game displays Time's Up! and allows the current level to be retried.

Tips & Strategies

1. Check available holes before moving a screw. A move is only possible when the destination hole is empty, so identify useful open positions before committing.
2. Target plates with two supporting screws. Removing or relocating enough supporting screws can change a plate from locked in place to unstable.
3. Use the one-screw state strategically. A plate supported by one screw can swing rather than immediately falling, so consider whether another screw must be moved before it can be released.
4. Save difficult positions with Undo. The Undo button restores the previous screw, hole, and plate state, making it useful when a move produces an unfavorable arrangement.
5. Use the timer as a planning constraint. Each level has a three-minute limit, so avoid unnecessary screw movements when the board already has a clear solution path.
6. Extra holes can create new destinations. When the existing holes are occupied, the add-hole action can provide another empty position for repositioning a screw.
