Connect Four is a two-player connection game.
Objective
To connect four of your checkers in a row while preventing your opponent from doing the same.
Gameplay
The players first choose a color and then take turns dropping one colored disc from the top into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own discs. For games where the board fills up before either player achieves four in a row, then they are a draw.
