Cat Sudoku Puzzle? Purr. You've found Catdoku! — the cozy logic puzzle where every cat just wants a little spot to call its own. Here's the deal, human: place exactly one cat in each colored region of the grid. Sounds simple? Look closer. Each cat insists on its own row and its own column, and no self-respecting cat will sit beside another — not even corner to corner. Every puzzle has one perfect solution, and a clever cat is hiding in plain sight until you find it. HOW TO PLAY • Tap once to mark a square with an X — "no cat here, thank you" • Tap twice to set a cat down in its spot • Guess wrong and you'll lose a heart; three slips and the puzzle curls back to the start • Follow the logic paw by paw, and every solution clicks into place 317 HAND-TUNED LEVELS Start cozy on a 6×6 grid, then stretch those whiskers across 7×7, 8×8, 9×9, 10×10, all the way up to a roomy 11×11. Every board is hand-crafted with exactly one correct solution — no luck, no guessing, just pure deduction. THE FOUR RULES • One cat in each colored region • One cat in each row • One cat in each column • No two cats touching — not even diagonally That's all you need. The challenge comes from how the regions are shaped, not from fiddly extra rules. PURR-FECT FOR EVERY HUMAN Rated 4+ with nothing scary inside — a calm, cozy brain stretch for anyone who loves sudoku, Queens, logic grids, or simply cats.

Challenging puzzles that really make you think and the cat theme is super cute. Plus tons of levels. Paying for ad-free is totally worth it! Awesome time killer! ### 4/5 — 342 Levels *2026-07-18* Great time. Loved playing this game for all 342 levels. Now it’s over🥺😭 **Developer response:** All 342 levels — that's a lot of cats safely rehomed. 🐾 We're a little proud and a little sad on your behalf. Dry those whiskers, though: the night cats pulled an all-nighter, and version 1.0.17 (on the App Store now) picks up right where you left off with a batch of extra-tricky new grids. More are coming. If there's a grid size or a twist you'd love to see next, tell us at redeyegame@163.com — after 342 levels, you've earned a say in it. ### 1/5 — Won’t advance *2026-07-17* I was enjoying this game until it would not advance past level 342. Tried updating several times but still won’t advance, very frustrating. **Developer response:** Meow, we're sorry — this one's on us. You reached level 342 and this cat simply refused to move, no matter how many times you updated. "Frustrating" is exactly the right word. The night cats have been working: version 1.0.17 is on the App Store now, with a fresh batch of levels waiting past 342, plus fixes for the stutter and for marks that would slip off the board. Update and the path should open right up. If anything still won't budge, hiss at us at redeyegame@163.com — we read every word. 🐾 ### 4/5 — Cute game, but stuck replaying level 342 *2026-07-11* I’ve had this game for a bout 2 weeks now and have been playing more days than not. It had an issue crashing last week that the recent update appears to have fixed. But now it won’t advance past level 342 for me. **Developer response:** Thank you for sticking with us through the crashing — and sorry that the moment we fixed one thing, level 342 turned into a wall. It was never meant to be the end of the road. Version 1.0.17 is on the App Store now with a fresh batch of trickier grids picking up right where you stopped, and we've also cleaned up the lag and a bug that dropped marks off the board. Anything else, meow at us: redeyegame@163.com. 🐾 ### 4/5 — Cute but freezes *2026-06-27* The first day I downloaded this game I enjoyed it immensely. Day two the problems began. I would play a level and it would freeze. To get to the next level I had to close out the app and reopen it. Very frustrating. When I tried to use a hint, nothing. Sometimes it froze when I tried to get a hint. It’s a shame the game doesn’t work the way it should. UPDATE: After I wrote my review I received a response apologizing for the glitch. The game was updated to fix the glitches and now it’s been working fine. I appreciate the quick response. **Developer response:** Meow… we owe you an apology, human. You loved us on day one, and on day two we froze up on the win screen and even sat on the Hint button — making you force-quit just to keep playing. That's not how a good cat behaves. We've swatted that bug under the sofa in the latest version (1.0.4), now on the App Store, so a quick update should get things purring again. If anything still freezes, please nudge us at redeyegame@163.com — we read every whisker-twitch of feedback and we'd love to win you back. 🐱 ### 2/5 — Cute but freezes *2026-06-16* The first day I downloaded this game I enjoyed it immensely.

To fix I have to delete and go back to app store. **Developer response:** You're right to swat us for this one. Making you delete and reinstall the whole app just to reach the next level? Embarrassing, even for a cat. We're truly sorry. That freeze is fixed in the current version (1.0.4) on the App Store — update when you can and we promise to keep the levels flowing. If we ever get stuck again, hiss at us anytime at redeyegame@163.com. Thanks for not giving up on us. 🐾 ### 4/5 — Cute game. Needs some bug fixes *2026-06-13* This is a fun and challenging game. Unfortunately, I have to close it after each win in order to get the next level to come up. The game does not automatically advance on its own. There are ads on occasion. It is not completely ad-free. **Developer response:** Thank you, human — a thoughtful review like yours is the best treat a cat can ask for. You're right: we should pad along to the next level on our own, and now we do in the latest update (1.0.4) on the App Store. We also heard you on the ads and we're working to keep them quieter and less in-the-way. If anything still feels off, drop us a line at redeyegame@163.com. We're a tiny litter of developers, and we'd love to earn that last star. 🐾 ## Frequently asked questions about Catdoku! Cat Sudoku Puzzle ### What are the basic rules of Catdoku?
