Goal

Drop colored discs into the 7×6 grid. Be the first to connect four of your discs in a row — horizontally, vertically, or diagonally.

VS AI

You play as 🔴 against the AI (🟡). The AI wins immediately when it can, and blocks your threats.

VS Friend

Two players take turns on the same device. 🔴 always goes first.

Controls

• Click or tap the ▼ arrow above a column to drop your disc
• You can also tap any cell inside a column on mobile
• Discs fall to the lowest empty row in the chosen column

What if the board fills up with no winner?

If all 42 cells are filled and neither player has four in a row, the game ends in a draw.

Are my scores saved?

Yes — wins, draws, and losses are saved in your browser's local storage and persist between sessions.

How strong is the AI?

The AI always takes a winning move when available and blocks your immediate threats. It then prefers center columns. It's beatable — try controlling the center from the start.
