A fun way to enjoy sudoku with a friend with this great board game! Race to get as many correct numbers in your colour as possible, during the agreed number of turns! First, put in the starter numbers from one of the 100 cards using the green disks. Now agree how many one minute turns you will both take and who will start - then off you go. Score for every correct number, but beware - wrong numbers are subtracted from your total. The red filter allows for extra clues and lets better players take on less practiced friends. For 1-2 players
