Connect 4

Board Browser game 4 plays

Drop a disc, claim a column, line up four — against the AI or a friend on the same screen.

Pick a column. The disc falls to the lowest free slot. Line up four in a row — across, down or diagonally — before your opponent does.

You never place a disc exactly where you want it. You choose a column and gravity decides the rest, which means every move also hands your opponent whatever square sits directly above it. That is the whole game: you are always building two things at once, your line and theirs.

WHAT'S INSIDE
— Play against the AI, or against a friend on the same screen
— The AI blocks a three-in-a-row and builds its own, so a lazy move gets punished
— Winning four are highlighted when the game ends, so you can see exactly what happened
— A clean board that stays readable at any screen size
— No download, no account, no waiting — press Play and the first column is yours

Connect 4 looks like a children's game and is not. Played well, it is a race to create two threats at once, because your opponent can only block one of them. Most games are decided several moves before anyone notices.
