Connect Four
Drop pieces into the grid to connect four in a row - horizontally, vertically, or diagonally. Play against the computer which will try to block you and set up its own four-in-a-row. Score tracks across rounds.
How to use
- You're Yellow. Click any column to drop your piece - it falls to the lowest empty row.
- Connect 4 of your pieces in a straight line to win. Lines can go horizontal, vertical, or diagonal.
- The computer plays Red. It will try to block your lines and create its own, so plan ahead!
- If the board fills with no winner it's a draw. Score is tracked across rounds in the session.

Connect Four is a vertical grid game where you drop colored discs into a 7-column, 6-row board. Discs fall to the lowest open slot in each column. First to get four of their color in a consecutive line, going across, down, or diagonally, wins. The computer opponent tries to block your lines while building its own.
The game looks simple but has real depth once you start thinking two or three moves ahead. Controlling the center columns is important because they open up more winning directions than the edges. Setting up a fork, where you have two different ways to complete four in a row and the opponent can only block one, is the key tactic to master.
