Screw Factory: Bolt Sort

Welcome to Screw Factory: Bolt Sort, a colorful 3D sorting puzzle where every bolt matters. Tap available screws, collect matching colors, and clear the workbench. The rules are simple, but limited tray space makes every move count. HOW TO PLAY • Tap an unlocked screw to unscrew it and move it into the sorting tray. • Match three screws of the same color to clear them automatically. • Remove the screws blocking your next move. • Clear the workbench to finish the level and continue to the next order. • Plan ahead: a full tray without a match ends the round. FOUR WAYS TO PLAY Choose Easy, Normal, Hard, or Expert. Start with a short introduction, then take on changing layouts, more screws, and tighter tray space. Your level and selected difficulty are saved on your device. HELPFUL TOOLS Undo your last move, get a hint, or restart the current puzzle whenever you need a fresh approach. A SATISFYING 3D WORKSHOP Enjoy glossy colored screws, metal rails, animated unscrewing, glowing matches, playful sound effects, and background music. Quick taps queue smoothly so you can keep sorting. Play offline without an account, ads, or in-app purchases. How many orders can you complete?
