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.
Connect Four Variants
Connect Four Glossary
- Four in a Row: The most common alternative name for Connect Four, used internationally.
- Disc: The round playing piece dropped into the board. Each player has 21.
- Column: A vertical slot on the board. The standard board has 7 columns.
- Threat: A position where a player needs only one more disc to complete a four-in-a-row.
- Double Threat: A position with two simultaneous threats. Since the opponent can only block one per turn, a double threat guarantees a win.
- Zugzwang: A position where any move you make worsens your situation — being forced to play helps your opponent.
- Solved Game: A game where the outcome with perfect play is mathematically known. Connect Four is a first-player win.
- Parity: The odd/even relationship between turn order and row positions, used in advanced strategy.

About Connect Four
Connect Four is one of the most iconic two-player strategy games of the modern era, published by Milton Bradley in 1974. Players take turns dropping colored discs into a vertical seven-column, six-row grid, with each disc falling to the lowest available position in its column. The goal is to be the first to form a line of four discs of your color — horizontally, vertically, or diagonally. What appears simple at first glance conceals considerable depth: with over 4.5 trillion possible game states, Connect Four rewards careful planning well beyond its accessible surface.
In 1988, mathematician James Allen proved that the first player always wins with perfect play on the standard grid. Despite this theoretical outcome, human games are rarely played perfectly, and the interplay of threats, double threats, and zugzwang keeps every match genuinely tense. Learning to spot and create “seven traps” — positions where you control both diagonals crossing a key square — is the hallmark of advanced Connect Four strategy.
How to Play Connect Four
Two players each choose a color of discs. Players alternate dropping one disc at a time into any of the 7 columns. The disc falls to the lowest empty row in that column. The first player to create an unbroken line of 4 discs — horizontally, vertically, or diagonally — wins. If the grid fills completely with no winner, the game is a draw.

Frequently Asked Questions
Is Connect Four free to play on Rare Pike?
Yes, completely free. No account or download needed.
Is Connect Four solved?
Yes — with perfect play the first player always wins. However, perfect play requires memorizing hundreds of key positions, so human games remain genuinely unpredictable in casual play.
What is a double threat in Connect Four?
A double threat is when you have two separate ways to complete a line of four on your next turn. Since your opponent can only block one, the other wins the game. Creating double threats is the most important advanced skill in Connect Four.
What strategy should beginners use?
Focus on controlling the center columns (central discs participate in more possible winning lines), work toward creating two simultaneous threats, and always watch for your opponent’s potential winning moves.
