About Nuts Puzzle: Sort By Color
Nuts Puzzle is the screw-and-bolt member of the colour-sorting family, and beneath the friendly presentation it is a properly rigorous logic puzzle. Coloured nuts sit stacked on a set of screws, and you win by rearranging them until every screw holds nuts of one colour only. The rule that generates all the difficulty is simple: you may only move a nut onto a screw that is empty, or whose topmost nut is the same colour as the one you are moving.
That single restriction means you can never dig out a nut from the middle of a stack directly. You have to unload everything above it first, and each of those nuts needs somewhere legal to go. Empty screw space becomes the scarce resource, and the puzzle becomes about ordering: which stack you dismantle first determines whether the rest of the board stays solvable.
Difficulty scales sensibly, adding both more nuts and more colours as you progress. Later levels genuinely require thinking three or four moves ahead, and the moment where a plan you formed twenty seconds ago cascades into a fully sorted board is exactly why this format has stayed popular.
How to play Nuts Puzzle: Sort By Color
- Look at the screws and note which colours are buried and which are on top.
- Tap a nut to pick it up: you always take the topmost nut from a screw.
- Tap a destination screw to place it. This is only legal if the screw is empty, or if its top nut matches the colour you are carrying.
- Continue moving nuts until each screw contains only a single colour.
- Complete the level to unlock the next, which will add more nuts, more colours, or both.
Controls
- Desktop: Click a screw to lift its top nut, then click another screw to place it.
- Mobile: Tap a screw to pick up its top nut, then tap the destination screw.
Tips and strategy
- Guard your empty screws. An empty screw accepts any colour, which makes it the most valuable thing on the board: filling one carelessly is the single most common way to lose a solvable level.
- Before moving anything, find the colour that is closest to being complete. Finishing it frees a whole screw and pays for itself immediately.
- Look for nuts that can move onto a matching top right now. Free moves that cost no space should always be taken before anything else.
- Think in terms of what a move unlocks, not what it tidies. A move that puts two nuts of the same colour together but blocks an empty screw is usually a net loss.
- When you are stuck, mentally work backwards from a finished screw. Asking "what would have to happen for red to be complete?" is far more productive than scanning for any legal move.
Nuts Puzzle: Sort By Color FAQ
What are the rules for moving a nut?
You always take the top nut from a screw, and you may only place it on a screw that is either completely empty or whose current top nut is the same colour. You cannot pull a nut out from the middle of a stack.
Can a level become impossible to solve?
Every level is solvable from its starting position, but you can move yourself into a dead end: usually by filling your last empty screw with a mixed stack. Restarting the level resets it to its solvable starting state.
Does Nuts Puzzle have a timer?
No. The game is untimed, so you are free to plan several moves ahead. The difficulty comes entirely from the logic of the arrangement.
What is the best strategy for hard levels?
Protect empty screws, complete nearly-finished colours first to free up space, and take any move that places a nut on a matching colour without consuming an empty screw. Planning three moves ahead matters more than moving quickly.
