Two players alternate dropping discs into a 7-column, 6-row vertical grid; each disc falls to the lowest empty cell of its column. Red always moves first. The winner is the first side with four of their discs in a straight line in any direction — across, up-and-down, or diagonal. A board that fills completely with no four-in-a-row is a draw. The game is fully solved: with perfect play the first player wins, which is why the opening move in the middle column matters so much.
Each turn is one gravity drop:
| Step | What happens |
|---|---|
| 1. Pick a column | Any of the 7 columns that still has an empty cell is a legal move |
| 2. The disc falls | Gravity drops it to the lowest empty cell of that column — discs never move again |
| 3. Check the lines | Four of your discs in a row (horizontal, vertical or diagonal) wins immediately |
Four in a Row is the classic two-player connection game played on a vertical 7x6 grid. Players take turns dropping discs into columns; gravity stacks them, and the first player to line up four of their own discs horizontally, vertically or diagonally wins.
7 columns by 6 rows — 42 cells. Each column holds up to 6 discs, and there are 69 possible four-in-a-row lines on the grid.
Red always moves first. The first move matters: with perfect play the game is a solved first-player win, and the strongest opening is the middle column.
Get four of your discs in a straight line — horizontal, vertical or diagonal — before your opponent does. The game ends immediately when a four is completed.
If all 42 cells are filled and nobody has four in a row, the game is a draw. Because every move fills one cell, no game can last longer than 42 moves.
Yes. The game was solved independently in 1988: the first player wins with perfect play, and the winning openings start in the middle column. Against imperfect defense, either player can still win, which is what makes it fun.
