Simple connect 4. If you don't know how to play, here are the rules: Players take turns droping pieces down the columns. If a player connects four of their color in a row (horizontaly, vertically, and diagonaly) that player wins. It's that simple. The four-in-a-row detection in this project (In Sprite3 if you download) has a long but quick and thorough detection system. It WILL detect any four-in-a-row. Allways.
