Free Hexa Sort & Stack Games

Hexa Tower is ArcadeOwl's arena for the hexagon sort-and-stack puzzle that took over 2026 — a deceptively simple drop-and-flow game with real bite. Each turn you place a small stack of coloured hexes on a post; matching tops on neighbouring posts flow together, and a tall enough single-colour stack clears with a pop. Greedy drops jam the board; patient ones build chain-reaction combos. Our 120 boards each play differently — post counts, colour counts, clear targets and group sizes form a unique recipe per game across two dozen themes and five difficulty tiers. Scores feed global and daily leaderboards. Free, instant, one-finger play.
