What is Nut Sort?
Nut Sort is a color sorting puzzle where you unscrew hex nuts from threaded bolts and spin them onto other bolts until each one holds four nuts of the same color. One tap moves the whole visible run of a color, so a single move can shift three nuts at once. The 60-level campaign climbs from 3 colors on 5 bolts to 12 colors on 15 bolts, adds mystery nuts on odd levels from level 5, and rates each clear with up to 3 stars against an exact move target.
