More games to play
Nuts Puzzle: Sort By Color asks you to tidy a row of bolts loaded with mixed colored nuts until each bolt holds just one color. It is a calm logic puzzle you play free in the browser, with nothing to install and no sign-up, so it works unblocked at school or work too.
What you do in Nuts Puzzle: Sort By Color
Every bolt starts with a jumble of colored nuts and your goal is to separate them. You take the top nut off one bolt and slide it onto another, repeating until each color sits on its own bolt. It is a solo puzzle, so the pressure comes from move order, not a timer.
Controls for sorting nuts
Pick a source, then pick a destination. The top nut is the only one that moves per tap.
| Action | How |
|---|---|
| Choose a bolt | Click or tap the bolt |
| Drop the nut | Click or tap the target bolt |
| Step back | Use the undo button |
| Restart | Use the reset button |
How the stacking rule works
You cannot drop a nut just anywhere. The target bolt has to be empty, or its top nut must already be the same color as the one in your hand. Buried colors force you to shuffle the pieces on top into legal spots first, which is where the puzzle earns its name.
Helpers and harder levels
Tools and twists show up as you climb the levels.
| Feature | What it means |
|---|---|
| Undo | Reverses recent moves, limited per level |
| Reset | Starts the level over |
| Extra bolt | Adds space, earned from chests and the wheel |
| Hard mode | Hides a nut's color until you clear the one above |
Tips to finish faster
A few habits keep boards from locking up.
- Hold one bolt empty as a working space.
- Complete a single color fully before moving to the next.
- Save undo for real mistakes since uses run out.
- In hard mode, reveal hidden nuts slowly and adjust.
