Owldoku: Logic Puzzle

500 hand-verified puzzles, a new daily challenge every morning, and not a single one that needs guessing. Fully offline.

Place one owl in every row, every column and every coloured region — and never let two of them touch. That's the whole game. You'll learn it in twenty seconds and still be thinking about it on level 300.

Owldoku is a star battle logic puzzle (you may know it as the queens game) wrapped in the friendliest animal on earth.

EVERY PUZZLE HAS EXACTLY ONE SOLUTION No guessing. Ever. Every single one of the 500 puzzles was verified to be solvable by pure logic — if you're stuck, there is always a deduction you haven't spotted yet. That's a promise, not a slogan.

A DIFFICULTY CURVE THAT ACTUALLY CURVES Levels start at a gentle 5x5 and grow to a genuinely demanding 10x10. Puzzles aren't shuffled at random — each one was measured by how much reasoning it takes, then placed in order. You'll feel yourself getting better.

DAILY PUZZLE, SAME FOR EVERYONE A fresh puzzle every day, identical for every player in the world. Build a streak, compare your time with friends, and share your result with a single tap.

BUILT FOR ACTUALLY PLAYING • Auto-X marks impossible cells for you when you place an owl • Drag your finger to mark several cells at once • Undo, clear, and a hint that points to a cell logic can prove • Three stars per level to chase
