Fill each tank to the right level. 1,040 water logic puzzles from Easy to Legendary, a new daily puzzle every day, and timed Puzzle Rush. Aquarium is a logic puzzle about water. Each grid is split into tanks. Fill them so that every row and column holds exactly the number of water cells shown by its clue. HOW IT WORKS • Water sinks to the bottom of each tank, with no gaps underneath. • Water in a tank is always level: if one cell in a row of a tank holds water, that whole row of the tank does. • The numbers beside each row and column tell you how many water cells it holds. • Use the clues to work out which tanks fill, and how high. WHAT'S INSIDE • 1,040 puzzles in eight themed packs, from Easy to Legendary • Grids from a quick 5x5 up to a big 15x15 • A new daily puzzle every day, with a streak counter • Puzzle Rush: solve as many puzzles as you can before the clock runs out • Hints that always help: they point out mistakes, explain the next step, or show you a cell. 25 free to start, and more for watching a short video • Undo, swipe to fill several cells at once, zoom for big grids, light and dark themes • Plays offline • Optional one-time purchases to remove ads or get unlimited hints If you like nonograms, sudoku or other grid logic puzzles, Aquarium gives you a fresh set of rules to master. Start with a small tank and work your way up to the Legendary grids.

I have never written an app review before but I felt the need to for this one.The app isn’t perfect, and sometimes the hints aren’t available or the easiest to understand. However, I really enjoy being able to play so many levels and so quickly! I’m autistic, so logic games are always my forte, but I was so excited to discover and play aquarium puzzles on an app! I’ve had it for two weeks and zipped through almost 500 levels. I’m going to be sad when I reach the end of available levels. :(

Thank you for writing your first review for us! Nearly 500 levels in two weeks is amazing. I've noted your feedback on hints. If you run low on levels, Daily Logic Puzzles has a new Aquarium puzzle every day.

Had an issue multiple times within the first 20 levels where the the labels for the clues were either impossible or were displaying for the wrong puzzle, sometimes the labels would change and be fixed upon reopening app but other times not

Developer Response
Sorry about that, and thanks for the detail. Clue labels showing for the wrong puzzle is a bug, and I've noted it. As you found, reopening the app sometimes clears it.
