Water Sort Legend is a free online color sorting puzzle game where your goal is simple: pour colored water between tubes until every tube holds just one color. Sounds easy at first, but with limited space and overlapping colors, you'll need to think several moves ahead to clear each level without getting stuck.

With over 150 handcrafted levels split across Easy, Medium, and Hard difficulty, the challenge ramps up steadily. The built-in IQ Estimator scores your performance based on how efficiently you solve each puzzle — fewer moves means a higher smartness score. Earn coins for every level you complete and spend them in the Upgrade Shop on boosters like Extra Tube, Color Helper, and a Coin Booster to make tough stages more manageable. The level unlock system keeps you progressing, and the clean sound effects make repeated attempts satisfying rather than frustrating.

Water Sort Legend is perfect for fans of liquid sort puzzles, color fill games, and brain training games that reward patience and logical thinking. Whether you're looking for a quick mental workout during a break or a longer puzzle session to grind through hard levels, this game delivers consistent challenge. Players who enjoy tube sorting games, water pouring puzzles, or IQ puzzle games online will find plenty to keep them busy across all difficulty tiers — all completely free, no download required.
