Watch Zoodoku in action
It's a calm brain teaser for short breaks: the rules take a minute to learn, and the boards grow from small 4×4 grids to tricky 10×10 ones.
How to play
- The board is a grid split into colorful enclosures.
- Each enclosure holds exactly one animal.
- Each row and each column holds exactly one animal.
- Animals can't touch each other, not even diagonally.
- Tap a square once to mark it as empty. Tap it twice to place an animal.
Pure logic, no guessing
Every board is checked by a solver before it reaches you. It has exactly one solution, and you can always work out the next move by reasoning. You'll never be stuck on a puzzle that only works by luck.
Puzzles that grow with you
Every level is rated easy, medium, hard or expert, based on the deduction techniques it needs. You start with simple steps, like a row with only one open square left. Later you learn to see how enclosures, rows and columns limit each other. Expert boards ask you to think a few moves ahead. The difficulty rises gently, with an easier board now and then to catch your breath.
Hints that teach
Stuck? Ask for a hint. Zoodoku doesn't just point at a square. It explains why the move is right, so you get better with every puzzle.
Daily puzzle
A new daily puzzle waits for you every day. Your best score of the day is saved, and your daily streak rewards you with gifts for coming back.
Duet mode
Duet is a harder version of the puzzle: every row, column and enclosure holds two animals instead of one. It unlocks after level 50 and starts with a short tutorial. Duet has its own levels and its own daily duet. It's still pure logic: every Duet board has exactly one solution.
