Connect Four is a game in which two players take turns dropping their colored discs into a 6 x 7 grid. Each disc falls straight down the grid and occupies the next available space in the player's chosen column.
Players must compete to form a horizontal, vertical, or diagonal line using four of their own discs. Discs must be placed in consecutive order and the first player to form a line with their discs wins the game.
If the entire grid is filled and neither players have placed four disks in a row, the game is tied.
