Connect Four (also known as Plot Four and Four In A Line) is a two-player board game in which the players take turns in dropping discs into a vertical grid with the objective of getting four of one’s own discs in a line.The game was published by Milton Bradley in 1974; a non-proprietary version is known as "The Captain’s Mistress". Connect Four has been solved independently by Victor Allis and James D. Allen. With perfect play, the first player can force a win by starting in the middle column. Starting in the two adjacent columns allows the second player to reach a draw; starting with the four outer columns even allows the second player to force a win.
