Otterdoku is a cute animal sudoku and otter logic puzzle with one simple goal: give every otter its own cozy spot on the grid. No numbers, no math and no guessing needed, just calm, clever logic. It's a brain puzzle game you can learn in seconds and enjoy for months.
🦦 HOW TO PLAY
The board is split into color regions, and otters need personal space:
• Each row holds exactly one otter
• Each column holds exactly one otter
• Each color region holds exactly one otter
• Otters never touch, including diagonally
Single-tap to put an X on any tile where no otter can fit. Double-tap to set an otter down. You get 3 hearts per level, so make every move a sure thing.
