Screw Nuts Snap Puzzle

How to Play

Screw Nuts Snap Puzzle sets a stack of see-through shapes in front of you, each one pinned in place by colored screws. Your task is to free the board by pulling screws out in a sensible order and dropping them into collection boxes. Every box takes three screws of a single color, so the trick is to spot which screws are uncovered right now and which color box is waiting. Spare slots hold screws that have nowhere to go yet, but they fill quickly, and running out of spare room ends the attempt. Peel the layers away one at a time until the board is empty. Later boards add an Unscrew mode where you move a screw into an empty hole instead of collecting it, which turns the puzzle into a question of routing rather than sorting. Progress stays in your browser, so you can return to the level you reached.

Controls

On desktop, left-click a screw or a button. On mobile, tap screws and buttons instead. In Unscrew mode, select a screw first and then the empty hole it should move to.

Tips

1. Look at which colored box is open before pulling anything, and take screws of that color first.
2. Treat the spare slots as emergency room, because every screw parked there makes the next move tighter.
3. In Unscrew mode, free the screws that block several holes at once before tidying single ones.
