Click either the circle or square then check the counter to the left to see how many corrects you got in a row. The chances are slim... (The game randomly rolls 1 or 2 and if you click red and it was 1 you get a point and if you click blue and it was 2 you get a point.)
I don't know when this idea came to my mind but it was in my unshared bin and I'm pretty sure I saw a game by Griffpatch similar to mine if so then thank you.
