Here’s a simple Tic Tac Toe game designed for the Mu Alpha Theta tournament at our high school. The way we played: 1) Teacher gives a math problem. 2) Either team can buzz in with the answer (in a Jeopardy still response). 3) If correct, the answering team chooses a square. 4) Then select the appropriate team button. 5) Hit R button to reset.
Multi-player only, no AI in this one.
