How to play Screw Out: Bolt & Nuts

Each bolt holds a stack of hex nuts in several tones. Click a bolt to lift the top group of matching nuts, then click another bolt to screw them on — you can only stack onto an empty bolt or onto a nut of the same tone, and no bolt holds more than four. Sort until every bolt is a single tone (or empty). Fewer moves is a better score.

Screw Out: Bolt & Nuts — frequently asked questions

How are the tones different if it is black and white?

Each nut has both a distinct grey shade and its own little symbol stamped on it, so you can always tell the tones apart.

Is every puzzle solvable?

Yes — each layout is generated by scrambling an already-sorted set with legal moves, so a solution always exists. Use the two empty bolts as workspace.
