Donhoop Color Stick

Donhoop Color Stick is a sorting puzzle built around a straightforward idea — move donuts between rods until every stick holds only one color. The rules are tight: you can only place a donut onto an empty rod or on top of a matching one. That constraint is what makes it interesting.

What starts as a relaxed few moves quickly turns into something that demands actual thought. A wrong transfer early on can lock up the whole board, leaving no clean path forward. The satisfaction comes from untangling those knots through careful sequencing rather than luck.

Puzzles grow more crowded over time, introducing more rods, more colors, and tighter margins for error. There's no timer pressure — just the quiet challenge of working out the right order before committing to it. Good for short sessions, though it tends to pull you into one more puzzle without much warning.
