ZooDoku: Sudoku de Bichos

Place each animal in its rightful place and train your reasoning skills by playing.

ZooDoku is a logic puzzle with the mechanics of Sudoku — but instead of numbers, you arrange cows, foxes, octopuses, lions, and dozens of other animals. The rule is simple and applies to everyone: no animal can be repeated in the same row, column, or block.

🐾 2000 LEVELS, FROM EASY TO CHALLENGING
Start with 4x4 boards on the Farm and advance to the 12x12 boards of crooked burrows in the Great Zoo. There are 40 worlds, each with its own animals and 50 levels. The difficulty increases little by little — no jumping from easy to impossible.

🎓 LEARN BY PLAYING
Never played Sudoku before? The first levels show the rules in practice, with highlighted squares and hints from beginning to end. And there, making mistakes doesn't cost anything. 🔥 DAILY CHALLENGE
Every day a new puzzle is created, the same for everyone. Play without spending lives and keep your streak going.

✏️ REAL TOOLS
Notes to mark possibilities, undo, hints when you get stuck, and automatic highlighting of related squares.

🔊 YOUR WAY
Sound, vibration, and daily reminder: each one turns on and off separately. The volume has three levels, because we know you play while waiting in line at the bank.
