Stack N Sort is a free online sorting puzzle game where you move colorful rings between poles and group them by color to clear each level. The core mechanic is simple to learn: tap or drag a ring from one pole to another, building same-color stacks until every pole is perfectly organized. The challenge ramps up fast as poles fill and your move options shrink.

What makes Stack N Sort genuinely addicting is the tension between limited pole space and increasingly tangled starting arrangements. You can't just move rings randomly – one careless move can block three others and force a restart. Each level is a logic puzzle in disguise. There are no timers, so you can think through your strategy, but the satisfaction of clicking through a clean, well-planned solution never gets old. The bright ring colors and smooth drag controls keep the gameplay feeling snappy and rewarding.

Stack N Sort is a great fit for fans of color sorting games, ring stack puzzles, and brain teaser games for adults and kids alike. If you enjoy tile matching games, tube sorting puzzles, or water sort-style challenges, this game scratches the same itch with a clean pole-stacking twist. Search terms like free ring sorting game online, colorful stack puzzle no download, and single player sorting brain game all lead here – and once you start, it's hard to stop at just one level.
