The rules take thirty seconds to learn. The puzzles go deeper than you'd expect.

■ Every level has one answer, reachable by logic alone All 1,300+ levels in Hamdoku passed machine verification. For every single one we confirmed that the solution is unique and that you can reach it by pure deduction — no guessing. You will never hit a "it's either here or there and I can't tell" moment. If you're stuck, there is always a clue you haven't spotted.

■ Hints, undo and notes are free — all of them The tools you reach for when you're stuck are never behind an ad. Tap 💡 Hint and it shows the next certain cell and the reason it's certain. Undo and ✕ notes are unlimited, always.

■ The rules · Each thick-outlined zone holds as many hamsters as its badge says · Exactly one per row and one per column · No two hamsters may sit in neighboring cells, diagonals included

Each new chapter adds one more rule: · Dwarfs — zones where two share a room · Light sleepers — they can't stand another hamster within two cells · Clutter — dark cells piled with belongings, where nobody fits

■ New to this kind of puzzle? That's fine Level 1 walks you through it move by move. Whenever a new rule appears, the game explains it before you start. You begin at 5×5 and grow from there.

■ Built to be relaxing · No timers — take as long as you like · Mistakes cost you nothing (a mistake limit is there in Settings if you want one) · Color-blind friendly mode — zones differ by pattern as well as color · Plays fully offline

■ No strings No in-app purchases. Supported by ads, and never an ad in the middle of a puzzle.

So — shall we get the hamsters settled in tonight? ## Rankings - #2,915,891 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.WAKE_LOCK` - `com.android.vending.CHECK_LICENSE` - `com.google.android.gms.permission.AD_ID` - `com.karnellabs.hamdoku.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Hamdoku: Sudoku Logic Puzzle](https://chrome-stats.com/d/com.mobirix.hamdoku) — 3,223 users, 4.63 / 5 - [Hamdoku - Brain Challenge Game](https://chrome-stats.com/d/com.dbg.hamdoku.challenge.game) - [Hamsternap: Brain Logic Puzzle](https://chrome-stats.com/d/com.hamster.nap.brain.game) — 2 users - [Hamdoku - Mind Puzzle Game](https://chrome-stats.com/d/com.mog.hamdoku.puzzle.game) — 898 users - [Hopsters](https://chrome-stats.com/d/com.tappanic.hopsters) — 118 users - [Hamster Out: Color Puzzle](https://chrome-stats.com/d/com.tlc.hamsterout) — 818 users, 4.54 / 5 - [Find My Hamster](https://chrome-stats.com/d/com.fungry.findmyhamster) — 172 users - [Bubu's Bakery: Spot the Diff](https://chrome-stats.com/d/com.tamhada.bubusbakery) — 1 users - [Save the Hamster：Puzzle Game](https://chrome-stats.com/d/com.duoduo.games.hamster) — 15,406 users - [Haydoku: Animal Sudoku Puzzle](https://chrome-stats.com/d/com.xorarcade.haydoku) — 4 users - [Hamster Dumpster](https://chrome-stats.com/d/com.impuzzlebly.hamsterdumpster) — 37 users - [Squeakdoku！](https://chrome-stats.com/d/com.squeaks.sdoku.top) — 1,641 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.karnellabs.hamdoku)
