About this game

A cozy logic puzzle about giving every hamster a place of its own.

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?
A hamster logic puzzle that never makes you guess. Hints and undo always free.
