Being unusually large, this Four-In-a-Row is perfect for outdoor use.
Four-in-a-row is played one on one. Each player has 21 chips. Whoever first gets 4 of their chips in a row wins. A row can be horizontal, vertical, or diagonal. If there is a draw, i.e., the entire playing field is filled with tiles, the round goes on.
Draw lots to see who starts.
