You need to click the green flag twice to play. This game is basically a codebreaker game where you remotely work with other scratchers to crack a code. (if you get the right digit in the right spot, it reveals it for the next player) if you crack the code, then you get to set the new code. when you set the new code, there are a few rules:it cant be longer than 15 digits, and you can only use numbers. to let everyone have a chance, You only get one chance every 10 minutes. also, the codemaster (the person who set the code) can't try to crack the code. Hope you enjoy :-)
