Race against another player to complete the same sudoku puzzle at the same time. You get a point for each number you get right. If you are not sure about a number you can guess... but be aware, if you guess wrong you will be blocked for 5 seconds and lose a point!

Do you think you are one of the best sudoku solver’s out there? Then come and prove it in this 2 player version of Sudoku. Sutwoku uses a unique rating system to rank players based on the number of games you have played and you have played against. We also have a Practice Game/Play with a friend feature for the more casual players.

Recently Added
- Hard Level Sudoku : We have just added a new sudoku level... Hard! Until now you have only been able to challenge yourself at Easy or Medium Sudokus. It's now time to see just how good you are at Hard level sudoku. We hope to add Insane level sudokus pretty soon!

Main Features

🧑‍🤝‍🧑 Play With A Friend
Play a casual practice game online against your friend. Winning won’t improve your rating but it will give you bragging rights!

🎮 Play Practice Game
If you are not ready for rated games or you just want to train your Sutwoku brain then a practice game is perfect for you. Practice games will not affect your rating.

🥇 Play A Rated Game
Complete in a rated game against a random Sutwoku’r. You will automatically be paired with another play of a similar rating. Win and your rating will increase. Lose… and it will go in the other direction!

🔳 Multiple Colour Schemes
It’s tough to find much of anything that people agree upon these days. In politics, it’s Red vs. Blue. In the superhero world, it’s Marvel vs. DC. When it comes to UI design it's Light vs Dark. So instead of us making that decision, we have provided both for you. Just pick the one you prefer!


Coming Soon
- We want to improve our ranking system to give players a more in-depth display of there they rank amongst other Sutwoku players
- Because 2 player sudoku is not crazy enough we hope to support different multiplayer versions, 3 player, 4 player maybe even 2v2!
