Finding Cleo

Cleo is hiding in the aquariums. Can you find every fish? Finding Cleo is a calm logic puzzle about fish, water, and careful deduction. Each connected tank contains exactly one fish, and fish can never touch—not even diagonally. Use the row and column clues, adjust each tank’s water level, and discover where Cleo and her friends are swimming. LEARN BY PLAYING A short interactive guide teaches every rule directly on the board. SOLVE 200 AQUARIUMS Progress through a handcrafted-style campaign that grows from small, friendly grids to challenging 10×10 puzzles, with lighter levels between tougher tests. THINK WITH WATER Tap to change a tank’s shared water height. Match the filled-cell totals shown beside each row and column to narrow down every fish location. FIND EVERY FISH Double-tap a cell to make your guess. Correct discoveries reveal a cheerful fish; incorrect guesses cost one of three hearts. PLAY AT YOUR PACE There is no timer. Water changes are free, undo is always available, and hints reveal useful information when you need a nudge. Bright aquarium art, friendly animation, sound, and haptics make every deduction satisfying. Find all the fish, set every tank to the right water level, and complete the aquarium.
