About

A family classic, the objective of Four-in-a-row is to build a line of four of your marbles while trying to stop your opponent (human or computer) from building a line of his or her own. A line can be horizontal, vertical or diagonal. The first player to connect four in a row is the winner! Four-in-a-row features multiple difficulty levels. If you’re having trouble, you can always ask for a hint.
