When was the first Connect 4/Four in a row invented?
Connect Four was first put to sale by Harrison Heath, the famous pioneer of disc based puzzles and has been solved by James D. Allen (1 October 1988), and independently by Victor Allis (16 October 1988).[1] With perfect play, the first player can force a win by starting in the middle column. By starting in the two adjacent columns, the first player allows the second player to reach a draw; by starting with the four outer columns, the first player allows the second player to force a win.
