About this game

[Fun Brain Puzzles Refreshed Daily]

What if Sudoku were cozier and filled with cute hamsters? That's Hamdoku!

Hamdoku is a pure logic puzzle that adds adorable, chubby-cheeked hamsters to the tight deduction of Sudoku. No numbers needed. Your one and only mission: find the perfect spot for every hamster!

[Simple Rules, Deep Strategy]
It takes seconds to learn, but it's never a pushover.

- One per zone: The board is divided into colored regions. Place exactly one hamster in each region, each row, and each column!
- Personal space: Hamsters can never touch each other - not even diagonally.
- Three sunflower seeds: A mistake costs you a seed, and you only get three. Guessing won't save you - every move counts!
- Hints & notes: Stuck? Hints help. Unsure? Take notes. Anyone can play without pressure.

[Game Features]

1. A New Daily Challenge Every Day
Solve today's puzzle and keep your streak alive. Race the stopwatch and beat your personal best!

2. Heart-Stealing Chubby-Cheeked Hamsters
Adorable hamster friends await you in every puzzle. Their round, lovely look brings a warm smile to your daily life.

3. Casual Relaxing Play Anytime, Anywhere
On your commute, before bed, or during a short break - no competition, just your own pace. Bright, cheerful graphics and a clean layout keep your eyes and mind at ease.

[Made for Queens, Star Battle & Minesweeper Fans]
Love the Queens puzzle, Star Battle or logic grid puzzles? Hamdoku uses the same rule: one per row, one per column and one per color region, with cute hamsters instead of queens. No numbers, no math, just pure deduction.
• Queens puzzle fans: the rules you already know, with a new puzzle every day
• Star Battle fans: the classic one-star rules, with chubby hamsters in place of stars
• Minesweeper fans: no lucky guesses, just careful deduction one safe move at a time
• Sudoku fans: the same row, column and region logic, without a single number

[More Reasons to Play]
• Brain games and logic games you can finish in minutes
• A new daily puzzle, streaks and a hard mode for sudoku and minesweeper fans
• Hints and notes, so even a tough logic puzzle never feels unfair
• Plays offline, no Wi-Fi needed
• Dark Mode for late-night puzzles

Same core mechanics as Meowdoku. Forced ads appear after every single level starting from level 20! It has the same approach to the first 20 levels, which can easily be completed without any hints. Forced ads totally ruin the experience of the game. This is just a reskin. Ad-free is €9.49/forever (or €3.79/week; €1.19/day), but who knows if the game is worth it and how different it really is compared to the zillions of reskins out there already.

Hello! 🐹 Truly sorry for the interruption caused by frequent ads. We are re-examining ad timing for smoother gameplay. Diverse, unique contents are already implemented in Hamdoku, so we hope you give them another look. Every effort will continue to show an even better side of Hamdoku! 🌻
