You know that clattering sound. It’s a rainy Tuesday, someone pulls a blue plastic grid out of a dusty box, and suddenly you’re staring down seventy years of gaming history. Most people think they know connect four how to play, but they usually treat it like a mindless distraction for six-year-olds. It isn't. Not really. If you play against someone who actually understands the math of the vertical grid, you’ll lose in about twelve moves, and you won't even see it coming. It’s brutal.
The game was officially released by Milton Bradley in 1974, though versions of "The Captain’s Mistress"—a similar game reportedly played by Captain Cook—have existed for centuries. It's a solved game. That means, mathematically, if the first player makes no mistakes, they win every time. But we aren't computers. We're humans with distractible brains and a tendency to miss the obvious.
Getting the Basics Right First
Let's talk setup. You’ve got a 7x6 grid. That’s seven columns and six rows. You have 42 tokens—usually red and yellow. The goal is dead simple: line up four of your discs in a row. This can be horizontal, vertical, or diagonal.

To start, you just pick a color and decide who goes first. In a casual setting, you might flip a coin. In serious play, players alternate who gets the first-move advantage. You drop one disc at a time into any of the seven slots. The disc falls to the lowest available space in that column. Gravity is your biggest ally and your worst enemy here.
Why the Center Column is Everything
If you take nothing else away from this, remember the number four. No, not because of the name. Because the center column (the fourth one) is the only column that can be part of a horizontal or diagonal line starting from any other point on the board.
If you don't control the center, you're basically playing with one hand tied behind your back. Most beginners scatter their pieces to the edges. Don't do that. It's a trap. By controlling the middle, you maximize your "connections." Think of it like a spiderweb; you want to be the spider in the middle, reaching out in every direction.
The Strategy Nobody Tells You About
There's a concept in connect four how to play called "threats." A threat is when you have three discs in a row with an empty space at either end. If your opponent doesn't block it, you win on the next turn. Simple, right? But the real pros use "double threats" or "forks."
This is where you set up two different ways to win at the exact same time. Your opponent can only block one. It’s the same logic as a fork in chess. You might have a horizontal row of three and a diagonal row of three that both rely on the same empty cell. Once you reach that point, the game is over. They just don't know it yet.
Watching the "Odd" and "Even" Rows
This gets a bit nerdy, but it’s how you actually win. Since the board has an even number of rows (six), the "parity" of the game matters. Generally speaking, the second player wants to control the even rows, and the first player wants to control the odd rows.
Why? Because when a column fills up, the person who plays the last disc in that column is usually the one who had "parity" there. If you’re trying to build a horizontal line on row 3, you need to make sure you’re the one who gets to drop a piece there. If you just mindlessly react to your opponent, they will dictate which rows get filled and when.
Common Mistakes That Make You Look Like an Amateur
Stop reacting. Seriously.
The biggest mistake people make when learning connect four how to play is playing defensively. If you spend the whole game blocking your opponent, you aren't building your own win. You're just delaying your inevitable loss. You have to force them to block you.
- Ignoring the Bottom Row: Many players build upward too fast. If you concede the bottom row, you’re giving your opponent a solid foundation to build any number of horizontal threats.
- The "L" Trap: Watch out for "L" shapes. If someone has two pieces on the bottom and one tucked just above them diagonally, they are setting up a multi-directional win that is incredibly hard to track once the board gets crowded.
- Forgetting Diagonals: Most human brains find horizontal and vertical lines easy to spot. Diagonals are sneaky. We tend to focus on the columns, forgetting that a win can slice right through the middle of the board at a 45-degree angle.
The Math Behind the Blue Grid
Back in 1988, Victor Allis solved this game. He used a database and a lot of processing power to prove that the first player can always force a win if they start in the center column. If they start in the two columns next to the center, the game might end in a draw. If they start on the edges? They can actually lose.
This doesn't mean the game is boring. It means it's a game of precision. Unlike Poker, there is no "luck" of the draw. Unlike Monopoly, there are no dice. It is a game of "perfect information." Everything you need to know is right there in front of you. If you lose, it’s because you missed something that was staring you in the face.
Advanced Tactics: The "Seven" Trap
One of the coolest ways to win is creating a "7" shape. Imagine three horizontal discs and two diagonal ones meeting at a single point. It creates a visual clutter that makes it very hard for an opponent to see which move is the actual killing blow.
You should also practice "blocking from above." Sometimes, the best way to stop an opponent's vertical climb isn't to play in their column, but to create a threat in a different column that forces them to waste their turn elsewhere.
How to Practice Effectively
Don't just play against your younger cousin. Go online. There are dozens of free Connect Four simulators that use the Allis engine. Play against the computer on the hardest setting. You will lose. A lot. But you’ll start to see patterns. You'll notice how the computer always prioritizes the center. You'll see how it sets up "traps" three moves in advance.
Actionable Next Steps for Your Next Match
If you're sitting down to play right now, keep these three rules in your head:
- Claim the Center: Get at least four of your seven discs in that middle column as early as possible.
- Look Two Moves Ahead: Before you drop a disc, ask yourself: "If I put this here, does it give my opponent a winning move on top of mine?" Never "solve" a column for your opponent.
- Check Diagonals Constantly: Every time a disc hits the board, scan the diagonals. They are the most common source of "sudden death" in casual play.
Mastering connect four how to play isn't about being a genius; it's about being observant. The board is small, the pieces are few, but the possibilities are enough to keep you busy for a lifetime. Start by controlling the middle, stay aggressive, and never, ever ignore a diagonal.
Key Takeaways for Dominating the Grid
- The Center is King: The middle column is involved in more potential winning combinations than any other.
- Parity Matters: Be mindful of who is filling the odd versus even rows.
- Forced Moves: Build threats that force your opponent to play where you want them to, not where they want to.
- Avoid the Edges: Only play the far-left or far-right columns when you absolutely have to or to complete a specific horizontal line.
By shifting your mindset from "dropping checkers" to "controlling space," you transform a simple childhood game into a tactical battle. Next time the pieces come out, you won't just be playing; you'll be winning.
