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.
■ Highlights
- A new kind of logic puzzle — great if you like Sudoku or nonograms (Picross)
- Easy 6×6, Medium 7×7, Hard 8×8, and a demanding Expert 9×9
- A hands-on 5×5 tutorial for first-timers
- One shared daily puzzle, every day
- Always exactly one solution — verified boards, no unfair dead ends
- Tap to cycle empty → water → cleared, or drag to pour
- Gravity assist auto-levels a tank as you fill it
- Records, streaks, and best times to keep you coming back
- Fully offline — no account, no sign-in, nothing sent to a server
