## What is Aquarium?

Aquarium is a water logic puzzle. Set the water level in each tank to solve the board. Water fills from the bottom and stays level across each tank. The numbers beside the rows and columns tell you how many cells must hold water.

Aquarium has 200 puzzles in 20 chapters, from small warm-ups to 9 × 9 boards. Every puzzle has one solution you can reach from the clues. Later chapters introduce stepped tanks, narrow passages, and clues that connect several tanks.

A short interactive tutorial shows you how to play. Hints explain where to look and why a deduction works before you choose to apply it. Undo and redo let you change course.

Aquarium Pro includes a daily puzzle that changes at midnight in your time zone. Each finished board becomes an aquarium with fish and plants. Keep it in your collection, mark it as a favorite, share an image, or replay the puzzle. Finish chapters to unlock garden, moonlit, and reef styles.

Play offline on iPhone, iPad, and Mac. Optional iCloud sync keeps your finished aquariums, favorites, and style on every device. No ads. The original 100 puzzles in chapters 1–10 are free. Aquarium Pro is a one-time purchase that unlocks all remaining puzzles, daily puzzles, and all future puzzles. There is no timer. Water sounds and haptics are optional, and a Still water setting pauses the animation.

Aquarium supports light and dark appearance, larger text, VoiceOver controls, Reduce Motion, and Increase Contrast.
