A quick guide to Connect Four
Read the Connect Four rulesWhat is Connect Four?
Connect Four is a two-player connection game on an upright grid of seven columns and six rows. Players take turns dropping a disc into a column that is not full, and the disc falls to the lowest empty cell. The first player to line up four discs horizontally, vertically or diagonally wins; a full board with no line is a draw.
What happens when the Connect Four board is full?
The game is a draw if all 42 cells are filled and nobody has four in a row horizontally, vertically or diagonally. A line of four or more wins immediately, so completing a line with the last disc still wins.
Who goes first in Connect Four on ChessPlayX?
