What Is Connect Four?
Connect Four is a two-player strategy board game invented in 1974 by Harold T. W. Scott of Milton Bradley (now Hasbro). The game is played on a vertical 7-column, 6-row grid — sometimes called the "7×6" grid — where players drop colored discs into slots and try to be the first to align four of their pieces in a row.
What makes Connect Four so enduring is the perfect balance between accessibility and depth. The rules take about two minutes to learn. But mastering the game — understanding the geometry of the board, predicting your opponent's moves, and setting up multi-threat plays — takes a lifetime.
It's a game that works for 6-year-olds at a family game night and for competitive players in championship tournaments. That range is rare and remarkable.
What You Need to Play
You don't need much to play Connect Four:
- The board — a vertical plastic grid with 42 slots (7 columns × 6 rows)
- Two sets of chips — traditionally red and yellow discs (21 of each)
- Two players — the game is strictly two-player; there are no solo or three-player versions in the classic rules
That's it. No dice, no cards, no scoresheet. Everything you need is in the box.

The Rules of Connect Four Explained
Here are the official rules, broken down step by step.
Setting Up the Board
- Stand the Connect Four board vertically, with the slots facing the players. The board has two horizontal supports — one at the bottom and one partway up — that hold it steady.
- Each player chooses a color. Traditionally, Red goes first, and Yellow goes second, though this is a convention rather than a rule.
- Place the 21 chips of your chosen color in front of you.
- The board should be positioned so both players can comfortably reach all seven columns.
The board's vertical orientation is central to the game — unlike most board games played flat on a table, gravity is Connect Four's most important mechanic.
How to Drop a Chip
On your turn, take one chip from your supply and drop it into any open column of the board.
Key rule: The chip always falls to the lowest available slot in that column. It cannot be placed in a mid-air position. It slides down until it hits the bottom of the column or rests on top of another chip already there.
- You can place your chip in any column that is not already full (i.e., has fewer than 6 chips in it).
- Once placed, a chip cannot be moved for the rest of the game.
- Players alternate turns, one chip at a time.
How to Win the Game
The objective is simple: be the first player to connect four of your chips in a straight line.
A winning line can be:
- Horizontal — four chips in a row across the same row
- Vertical — four chips in a column
- Diagonal — four chips in a diagonal line (slope can go either direction)
The winning four must be contiguous — they must be directly next to each other with no gaps.
As soon as a player achieves four-in-a-row, the game ends immediately. That player wins.
When Is It a Draw?
If all 42 chips are placed on the board and no player has connected four, the game is a draw. This is sometimes called a "full board" draw.
Note that draws in Connect Four are statistically rare when both players play optimally — the first player (Red) has a mathematically proven winning strategy. But in casual play, draws happen regularly, especially among beginners who are still learning to read the board.
5 Tips Every Beginner Should Know
Now that you know the rules, here are five tips that will help you play better from your very first game.
1. Control the Center Column
The center column (column 4 of 7) is the most powerful position on the board. From the center, you have the most potential lines of attack — you can reach horizontal spaces on both sides, and diagonals in multiple directions.
If you can establish a strong presence in the center early, you'll have more paths to victory and more ways to threaten your opponent simultaneously.
2. Always Watch for Three-in-a-Row
Before you make any move, scan the board for three-in-a-row configurations — yours and your opponent's. A three-in-a-row is one move away from a win, which means:
- If you have three-in-a-row, you're one move from winning. Can you complete it this turn?
- If your opponent has three-in-a-row, you must block them immediately, unless you can win yourself.
Making this scan a habit will dramatically reduce the number of games you lose to surprise victories.
3. Think Two Moves Ahead
Connect Four rewards forward thinking. Before you place a chip, try to imagine:
- What will the board look like after this move?
- What three-in-a-row opportunities does this create?
- What three-in-a-row opportunities does this create for my opponent?
This mental simulation takes practice, but it's the single biggest skill gap between beginners and intermediate players.
4. Don't Just Attack — Also Play Defensively
It's tempting to focus entirely on building your own winning line. But Connect Four is a reactive game — your opponent's threats often matter more than your own plans.
A good rule: before every move, check if your opponent can win on their next turn. If yes, block first. If no, then execute your own strategy.
5. Watch for the "7-Win" Setup
Advanced players talk about creating multiple threats — situations where you have two different ways to win on your next turn, and your opponent can only block one.
Once you understand the geometry of the board well enough to spot and create these dual-threat positions, you'll start winning far more games. It takes practice, but it's the skill that separates casual players from serious Connect Four students.
Frequently Asked Questions
Can You Play Connect Four Online?
Yes! You can play Connect Four online right here — no download or account required. Play against a friend or against the computer at various difficulty levels.
Is Connect Four Solved?
Yes — Connect Four has been mathematically solved. With perfect play from both sides, the first player (Red) always wins. The solution was found in 1995 by computer scientists using brute-force search algorithms. The entire game tree was analyzed and mapped.
But don't worry: most people you play against are far from perfect. There's still plenty of room to win games at every level.
What's the Best Opening Move in Connect Four?
The mathematically proven best opening move is to drop your first chip into the center column. From there, you maintain the most flexibility and keep the most options open for the rest of the game.
How Many Chips Are in Connect Four?
There are 42 chips total — 21 red and 21 yellow. Each player gets 21 chips, which is exactly enough to fill half the board.
Can You Block a Diagonal Win?
Yes — diagonals are just as legal as horizontal and vertical wins. You must defend against diagonal three-in-a-row formations just as you would against any other threat.
Is Connect Four a Game of Luck or Skill?
Connect Four is primarily a game of skill, though there is some luck in how your opponent plays. Unlike dice-based games, every piece placement is a deliberate choice. The better thinker wins more consistently — which is why Connect Four tournaments exist and why the game has been studied by mathematicians and computer scientists.
