Connect Four

How to play

Click any column to drop your disc into the lowest open slot. Red and Yellow alternate turns, and the first player to line up four discs in a row — horizontally, vertically, or diagonally — wins the round. It's a local two-player game: pass the device back and forth, or sit side by side.

Frequently asked questions

Is this against a computer or another player?

Another player, locally — there's no computer opponent. Take turns on the same device.

Is the score saved?

Only for the current session. Red and Yellow's win counts reset when you refresh or leave the page; "New round" keeps the running score, "Reset score" clears it.

Any strategy tips?

Controlling the center column gives you the most ways to build a line, and watching for your opponent's three-in-a-row threats — and blocking them — matters more than rushing your own.
