About Aquarium
Fill enchanted tanks to match the water totals along each row and column. Water must sit at one flat level within each tank, even when its shape is irregular.
How to play
- Goal
- Mark water in the irregular tanks so every row and column reaches its shown total and each tank has one flat waterline.
- How it ends
- A board is won as soon as all water is correctly marked; there is no loss, and dry marks are optional.
- Record
- Your first solve time is kept for each board, and the fastest verified first solve appears beside the board and in the page trophy.
- A tank is a region inside thick borders. Its water is flat across a row and fills every lower row of that tank.
- The number beside a row or above a column says how many cells in that line must contain water.
- Tap to cycle unknown, water and dry; dry marks are optional. Mark every water cell to finish.

Good to know
The sixty boards are fixed, deducible and independently counted to one answer. No hint or answer key ships in the game. The timer begins when a board opens and never pauses; only a first solve can rank. Progress, sound and reduced-motion preference are kept in this browser.
