About Wood Nuts & Bolts
Wood Nuts and Bolts is a colour-sorting puzzle with a hardware-store theme. Coloured nuts are stacked on a set of bolts in a jumble, and you unscrew them and move them around until each bolt holds nuts of a single colour. Sort them all and the level is solved.
The familiar sorting logic gets a satisfying mechanical feel. You can only move a nut onto an empty bolt or onto a matching colour, so free bolts are precious and the order of moves decides whether a board opens up or locks tight. Later levels add more colours and tighter space.
This browser version saves your progress and plays the same on phone or desktop. It is a calm, tactile sorter, the kind of game where the clink of a nut landing on its matching stack is oddly satisfying.
How to play Wood Nuts & Bolts
Unscrew nuts from the bolts and move them so each bolt ends up holding a single colour. You can only place a nut on an empty bolt or on top of a matching colour. Keep a bolt free to work with, and sort every bolt to one colour to complete the level.

Tips & strategy
- Keep at least one bolt empty as working space, or the board can jam.
- Gather one colour completely before starting the next.
- Move nuts onto the larger matching stack to free a bolt sooner.
- Check the bottom nut on each bolt to plan your moves.
- Use undo to test a line, since every level is solvable.
