A simple tic - tac - toe for the Comuter Science Teachers' Scratch Day Event in Athens (10 Apr 2010). The application could be used as a nifty assignment to students. Teachers can use this application to introduce and discuss concepts like game space trees, minmax algorithms, heuristics etc After the green flag click on a tile to play X. Then choose one of the cats to play as opponent. Red cat plays randomly while the other applies basic heuristic rules.
