Four in a Row is a strategy board game played by two players. It is based on the idea of the famous board game, Four in a Row. It is played on a grid that is divided into 64 squares.

The game starts with both players placing a single piece of their respective color (red or yellow) in the first free square of the grid. This is called the "first turn". The players then take turns, alternating between placing a single piece of their color in a new square and moving their existing piece to an already occupied square. This is called "going in turn".

The goal of the game is to connect four of your pieces in a line of three or more pieces of your color, without your opponent doing the same. If you succeed in connecting four of your pieces, you win the game.

The game can be played with two players on a single computer or with multiple players on a single computer.
