What is Fish Sort Puzzle?

Fish Sort Puzzle is a browser-based sorting game built around three connected decisions: which bubble to open, which creature to keep in the tray, and which triple to finish first. Only the top fish in each stack can move, so every match changes what becomes available next.

The objective is simple—clear the board—but the limited seven-slot tray rewards forward planning. A nearly finished pair is useful; a tray full of unrelated creatures is dangerous.

What makes this version different?

The game combines layered bubbles with triple matching and aquarium orders. It runs as a lightweight HTML5 game, so you can play on a phone or computer without installing an app.
