Connect 4 or Four In A Row is a two-player strategy game that involves dropping colored discs into a vertical grid. The goal of the game is to connect four discs of the same color vertically, horizontally, or diagonally before your opponent does.

The game starts with an empty grid, and each player takes turns dropping a colored disc into one of the grid’s seven columns. The disc will fall to the lowest unoccupied space in the column. Players must strategize and anticipate their opponent’s moves to block potential connections while trying to make their own.

The game ends when one player successfully connects four discs or when the grid is completely filled with discs without either player connecting four. Connect 4 is a classic and popular game that can be enjoyed by players of all ages.
