Connect Four

Just like physical forms of Connect Four, the object of the game, whether in one or two-player mode, is to get four checkers in a row either horizontally, vertically, or diagonally. The player(s) drops checkers at the top of a 7 column by 6 row playing area, trying to get the needed four-in-a-row either against a second player or the computer. Winning requires strategy both to be able to achieve a four-in-a-row, but also to ensure that the computer or human opponent doesn't get four-in-a-row first.
