Nuts & Bolts Puzzle: move bolts, free the hanging ball
Nuts & Bolts Puzzle turns each stage into a bolt-swap layout: move a screw into the open hole, release the chained ball, and clear the wooden board. The simple setup hides a real order puzzle, because one blocked opening can change the whole path, and the multiple themes keep the board easy to read.
This sits neatly in the nuts and bolts puzzle style, where every move has to open space before the next screw can move. It runs free online in your browser, so you can try a few levels on mobile or desktop without download or signup.
Each cleared board awards points and sends you to the next level, which keeps the focus on sequencing rather than speed. The challenge rises as more bolts share the same board space, and the later stages ask you to check the layout before you pull the first piece.
Level pressure, multiple themes, and hell difficulty
The old mode notes also mention a hell difficulty, so there is a harsher route once the basic stages feel familiar. If you enjoy planning move order and board access, the game fits a strategy games mindset even though the action stays inside a compact puzzle board.
If you want close mechanical matches, Crazy Screw King uses the same screw-relocation idea to open the board, while Screw Puzzle Master follows the same unscrew-and-replace logic. Wood Nuts Master: Screw Puzzle is another strong comparison because it also uses wooden layouts and bolt-based clearing.
That makes the game a good pick when you want a browser puzzle with clear rules, a steady difficulty ramp, and no setup before you start. Every level is about spotting the right empty hole, moving the bolt at the right time, and watching the ball drop so the board can open up.
