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

idk but this game has some hackers. i was playing the game and was 1st in the leaderboard with another player. we both were playing the same time while other players on the leaderboard were offline. only the two of us had similar points like 345/8 and others were on 100 points. then out of nowhere some other player get into the 1st position in the leaderboard with 400 points in one second! how is that even possible? this happened to me twice now. it's not fun playing this game anymore!

I enjoy this game a lot so far!! The art style is really cute and the ads aren't too intrusive. I do wish there was an option to remove the text that says you did better than ??% of other players, as I play mainly to wind down and not for speed, but it's not too big of a deal!

Hi! Thank you for playing and for the thoughtful feedback 🐹 Playing to wind down rather than to race is exactly how a lot of our players use the game, so the idea of hiding the percentile message makes a lot of sense. We'll pass it along to the team to look into. Thank you for taking the time to share this — enjoy 🌻

We're sorry for the inconvenience 🐹 Hamdoku can indeed be played offline. The issue occurred in the Golden Seed Challenge, where a lack of connection froze entry to the match. This has been fixed in the latest version, so please update the game and try again. Thank you.
