About Nuts And Bolts Screwing Puzzle

Nuts and Bolts Screwing Puzzle is a tidy little logic game about taking things apart. Several wooden boards are pinned to a wall with bolts, and boards overlap so that some bolts pass through two or three of them. Pull a bolt out and it must go into another empty hole; if that hole is covered by a board, you cannot use it. Free every board and the level is done.

Early levels are almost relaxing. Later on, boards are stacked deep, holes are scarce, and pulling a bolt at the wrong moment can drop a board over the only hole you needed. The game quietly becomes a planning puzzle where you look three or four moves ahead.

How to Play Nuts And Bolts Screwing Puzzle

1. Tap a bolt to pull it out, then tap an empty hole to screw it back in.
2. A board falls away once none of its holes contains a bolt.
3. Holes hidden under a board cannot be used until that board is gone.
4. Remove every board to finish the level.

Controls

• Mouse: click a bolt, then click a hole.
• Touch: tap a bolt, then tap a hole.
• Undo button: reverses your last move on levels that allow it.

Tips and Tricks

• Count the free holes before you start. A level with only one spare hole needs an exact sequence.
• Free the top board first whenever possible, because it uncovers holes for the boards beneath it.
• Avoid parking a bolt in a hole that another board will need after it drops.
• If a level looks impossible, look for a bolt that holds only one board. That is usually the first move.

Nuts And Bolts Screwing Puzzle FAQ

Does the order really matter?

Yes. Since bolts must go into a free hole, moving them in the wrong order can leave you with no legal move.

Is there a time limit?

No. Take as long as you like on each board arrangement.

What happens if I get stuck?

Use the undo or restart button. There is no penalty for restarting a level.
