AQUARIUM: Water Logic Puzzle

Pour water into the tanks and match every number. There is always one answer, so you never hit an unfair dead end. Offline, calm, and perfect for a short break.

Pour water. Match the numbers.

AQUARIUM is a fresh logic puzzle where you read water levels across a divided grid. No flashy effects — just the quiet satisfaction of filling a board with clear water, one careful move at a time.

■ Simple rules Thick walls split the board into tanks. Water settles at the bottom, so the surface is always level. The number beside each row and column tells you how many of its cells hold water. Find the levels that match every number and you win. You'll learn it in a minute; the depth keeps going.
