What a player should see
Remaining moves sit near the board. Locked nuts look different from ordinary tops. The toolbox is labeled as a park slot, not a second rack. Settings for sound and haptics are switches, not hidden menus.

Interface design
We map each tap: source bolt, target bolt, toolbox, pause, and clear. The visual system for Nut Bolt Sort uses a rose workshop palette and optional colorblind patterns.
Accessibility notes
Colorblind patterns are a player setting stored on the device. This website also aims for readable type and a skip link. See Accessibility.
