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?
