Unscrew in the right order — the boxes only take their own color!
About this game
Colorful screws pin down a stack of wooden plates. Tap a free screw to unscrew it: it flies into the box of its color, or waits in one of 5 holding slots. Boxes fill 3 screws at a time in a fixed order — remove every plate without overflowing the slots. 14 hand-tuned, solver-verified levels from gentle 2-color stacks to 5-color deep exams.
