Oridoku: Brain Puzzle Games

Looking for a game that calms you down and still makes your brain work? Oridoku is a pure logic puzzle: the rigor of Sudoku with the deduction of Queens, on boards made of folded paper.

💡 Simple rule, deep strategy
• Territory: the board is split into colored regions, and each color has its own origami animal: owl, fox, dog and more. Each region gets exactly one.
• Personal space: origami never share a row or a column, and never touch, not even diagonally.
• No guessing: every board has exactly one solution, and you can always reason your way to it. Three mistakes end the round, so every tap counts.

✨ What you get
1000+ levels that teach
Early boards are small and show you the idea. Then they grow, from 5×5 up to 10×10, and each new technique arrives on its own, with room to practice before the next.

🧠 Help when you're stuck
A hint that shows the next deduction and explains why. Reveal to place one fox. A pen to sketch ideas over the board.

📅 A challenge every day
A fresh board each day and a streak to keep.

🌙 No interruptions mid-game
• No ad ever interrupts a round. Nothing full-screen in the middle of a board or after a loss.
• No timer on screen. Play at your own pace.
• Works offline, no account needed. Your progress comes back if you reinstall.
• Light and dark theme. In English, Portuguese, Spanish, French, Italian and German.

❤️ Why Oridoku stays on your phone
No social mechanics, no grind. It takes seconds to learn, and long after you put the phone down the logic is still turning in your head. Perfect for the commute, the queue and the morning coffee.
