How it works

Step 1

Create

Step 1 - Create

Create a new game

So you want to play a live multiplayer game Sudoku against your friends? Great! Head over to Create a New Game, select your desired difficulty and go!

Step 2

Invite

Step 2 - Invite

Invite your friends

You'll see your game's unique 4-letter code, e.g. PLAY. Send this code to your friends, or forward them the Join link you'll see. You, and each of your friends, can provide a user name and you'll receive a random color, e.g.

Batman

, which will be used to denote your blocks.

Step 3

Get Started

Step 3 - Get Started

Let's get going!

Your friends are here, your thumbs are stretched, so there's only one thing left to do - Hit Start. You'll be transported to the game screen, which should look and feel familiar.

Step 4

Score

Step 4 - Score

Go forth and score

Your mission is to play Sudoku as normal, with a twist: The first player to solve a block correctly gets 10 points, the second player 6, the third player 3 and the rest 1. Give an incorrect answer and not only do you lose points, but you're out of the running to score that block entirely.

Are you ready?
