About

Aquarium: Living Logic is a calm water puzzle. Every tank has exactly one answer, and you can reach it by deduction alone. HOW IT WORKS • The board is split into tanks of different shapes. • Set a water level in each tank. Water lies flat and fills from the bottom. • The numbers beside each row and column say how many cells hold water. • Match every clue, and your finished aquarium comes alive with kelp, bubbles, and a goldfish. NO GUESSING Every puzzle is checked for a single solution that you can reach from the clues, one deduction at a time. When you get stuck, a hint shows where to look, explains the reasoning, and then offers to apply it. Undo reverses any move or hint. WHAT'S INSIDE • 60 puzzles in six chapters, from 4×4 warm-ups to an 8×8 finale • A daily puzzle that changes at midnight UTC • A short interactive tutorial • A gallery of every aquarium you finish, ready to share as an image • Light and dark themes that follow your device, on iPhone and iPad CALM BY DESIGN No timers, streaks, ads, accounts, or subscriptions. Everything works offline. Water sounds and gentle haptics are optional. ACCESSIBLE VoiceOver reads every cell with its water and clue counts. Aquarium supports Dynamic Type, Reduce Motion, and a stronger-contrast mode. Aquarium: Living Logic is free, with every chapter included.Read more
