Loosen up. Screw Sort is the oddly satisfying puzzle about pulling screws in just the right order to free stacked plates — then watching them tumble away. Tap a screw to unscrew it and send it flying into the matching colored slot. Fill a slot group of three and it clears with a sparkle. But mind the order: a screw pinned under a higher plate is locked until you clear what's on top. Run out of slot space and it's back to the toolbox. • 200 hand-tuned levels with a gentle difficulty curve • Simple one-thumb controls — unscrew, sort, solve • Chunky, colorful plates and screws that are a joy to touch • Colorblind-friendly: every screw color has its own shape • Boosters when you're stuck: extra slot, magnet, undo • Daily rewards and a level map to track your stars No timers, no pressure — just clean, clever, satisfying sorting. Can you free every plate with three stars? Screw Sort is free to play with optional ads and in-app purchases. Remove ads or grab coin packs any time.

Yarn cubes are arranged in layers above the canvas. Selecting an available cube separates it into ten smaller yarn balls and places them on the outer track. Each ball is used to cover a corresponding colored cell in the picture. The level is complete when every cell has been filled.
