If you have ever watched colored discs fall into a vertical grid and wondered what comes next, this beginner's guide will help. Connect 4 is a two-player strategy game with one simple goal: be the first to form a straight line of four of your own discs. The line can run across, up and down, or diagonally.

Connect 4 rules are straightforward, but small details can decide close games. Where does a disc land? What counts as a diagonal win? Can you use a full column? And what happens if neither player manages to connect four?

Want to win more Connect 4 games? The best improvement is not a secret opening or a trick that works against every opponent. Connect Four has only seven columns, but the number of possible board positions is enormous.

What is the best first move in Connect 4? On the standard seven-column board, the strongest opening is the center column, column four. This is more than a popular tip: mathematical analysis of the classic game shows that the first player can force a win from the center with perfect play.

The challenge grows when the opponent notices threats, blocks your obvious wins, and forces you to choose between difficult moves. Knowing how to beat a Connect 4 computer therefore begins with understanding the board rather than relying on a trick.
