About this game
Screw Nuts Snap Puzzle asks you to think a few moves ahead. Every board is built from layered glass shapes, and only the screws on the outer edge can be removed. Pull them out and drop each one into the collection box that matches its color. Three matching screws fill a box, and the order you pick them in decides whether the board stays under control.
The spare slots are the real challenge. They give you room to park screws temporarily, but once they fill up the level is lost. That means you constantly need to weigh which screw to free next and which one can wait. Unscrew mode turns the puzzle around: you pick a screw, then an empty hole, and move it manually. Later stages add tougher boards and cat-rescue puzzles.
For the hardest layouts you can use extra slots, swap boxes, or call on a hammer. Everything runs in the browser with a mouse or touch input, and your progress is saved locally in that same browser.
How to play
Click a screw that is exposed on the outside, then click its matching color box. Three screws of one color fill the box. In Unscrew mode, select a screw first and then an empty hole to move it. On touch devices, simply tap screws and buttons.
