Your goal is simple: remove every screw and sort it into the matching color tray. Sounds easy? Think again. Screws are packed together, and your available holes are limited. Every move matters.
🛠️ PLAN YOUR MOVES
Tap the right screw to remove it and send it to its matching tray. If a tray isn't available yet, screws can temporarily be placed in free holes—but space is limited. Fill the holes with no possible move left, and the puzzle is over!
