Click the green flag to start. Then guess the lottery number. (0-99) When the cat asks you to use chance, you may say y or n. If you say y, the first digit of lottery will change to the first digit of your prediction. You have to guess the second digit. Tip: if you are going to put number between 0 and 9, put 0 in front of it. (ex. if you are going to say 3, put 03 as the prediction.)
