Connect Four (also known as "Four in a row") is a two-player board game in which the objective is to be the first to get four of one's own discs in a line.
The simple goal of the game is to arrange four pieces in a row.
Horizontal, vertical, and diagonal lines are valid.
The game is played on a board with Small, Medium and Large board, which is placed in a vertical position. The players take turns in dropping button in one of the non-full columns. The button then occupies the lowest unoccupied square on that column. A player wins by placing four of their own button consecutively in a line (row, column or diagonal), which ends the game. The game ends in a draw if the board is filled completely without any player winning.
