Four in a Row

The Ultimate Guide to Connect Four (Four in a Row)

Connect Four — also known as Four in a Row, Four Up, and Captain's Mistress — is one of the world's most popular two-player strategy games. Created by Howard Wexler and first sold by Milton Bradley in 1974, Connect Four has become a staple of family game nights, classrooms, and competitive gaming. Simple to learn but surprisingly deep to master, it's a solved game where perfect play by the first player always leads to a win.

Key Game Specifications

How to Play Connect Four: Complete Rules

1. Setup

The game uses an upright board with 7 columns and 6 rows. The board starts empty. Players choose their color — red or yellow.

2. Taking Turns

Players alternate turns. On each turn, a player drops one of their colored discs into any column that isn't full. The disc falls to the lowest available position in that column (gravity). The first player (red) goes first.

3. Winning

The first player to form an unbroken line of four of their discs wins the game. The line can be:

• Horizontal: Four in a row across a single row.
• Vertical: Four stacked on top of each other in a single column.
• Diagonal: Four in a diagonal line (ascending or descending).

4. Draw

If all 42 slots are filled and neither player has connected four, the game is a draw. This is rare in casual play but more common between experienced players.

Connect Four Strategy: How to Win

1. Control the Center Column

The center column (column 4) is the most powerful position on the board. A disc in the center can be part of connections in more directions than any edge or corner position. Always play the center column on your first move if possible.

2. Build Multiple Threats

The key to winning is creating a position where you have two ways to win simultaneously. Your opponent can only block one threat per turn, so having two open-ended three-in-a-rows guarantees a win.

3. Use the "Odd/Even" Rule

Rows are numbered 1 (bottom) to 6 (top). Since the first player plays on turns 1, 3, 5... they will fill odd-numbered positions in a column first. Understanding this parity can help you set up threats that land on your turn rather than your opponent's.

4. Plan Ahead with Vertical Traps

Stack three discs in a column, forcing your opponent to block the fourth. Meanwhile, this block might set up your winning move elsewhere. Vertical threats are easy to see — use them as decoys to set up diagonal or horizontal wins.

5. Avoid Playing Under Your Opponent's Winning Square

Before placing a disc, check whether your move will allow your opponent to play in a winning position directly above. This is the most common mistake in Connect Four — gifting your opponent a win by building under their threat.

6. Control the Lower Rows

Connections in the bottom three rows are easier to build because fewer discs need to be placed to reach them. Threats higher on the board are harder to activate and easier for opponents to defuse.

The Mathematics of Connect Four

Connect Four was solved in 1988 by Victor Allis. He proved that the first player can always force a win with perfect play by starting in the center column. The total number of possible board positions is approximately 4.5 trillion. Despite being solved, the game remains deeply challenging for humans because the perfect strategy requires calculating dozens of moves ahead.
