What is Bolts and Nuts Online?
Boards are covered in plates held down by bolts and nuts. Plan which bolt comes out and when. Every plate you set loose clears a little more of the level through pure logic.
How to play
Click a bolt to pull it out, then click an empty hole to screw it back in there. Any plate left without a bolt falls under gravity and leaves the board. Unscrew in the wrong order and plates can slide over each other and lock other bolts in place. Remove every plate to finish the level. Later boards bring more layers and fewer spare holes.
Controls
| Key | Action |
|---|---|
| Left click | Pick a bolt and move it to an empty hole |
| Tap | Pick and place a bolt on a phone |
Tips
- Start with the bolts holding the topmost plate, because the lower ones only show up after it is gone.
- When spare holes are scarce, plan each move so it frees one plate completely.
- If a single bolt holds a plate, check whether that plate will snag on another one as it drops.
