CONNECT 4 ONLINE – CONNECT FOUR GAME

Connect 4 is the classic two-player strategy game: drop red and yellow discs into a grid of 7 columns and 6 rows and be the first to line up four in a row – across, up and down, or diagonally. Play Connect Four online right here, free and with no download: challenge the computer on Easy, Medium or Hard, or play with a friend on the same screen.

How to play Connect 4

• Players take turns dropping one disc into a column. The disc falls to the lowest free space.
• Line up four of your discs horizontally, vertically or diagonally to win.
• If the board fills up and nobody has four in a row, the game is a draw.
• Tap a column to drop your disc, or use the arrow keys and Enter. Undo takes back your last move.

Play Connect 4 against the computer or a friend

vs Computer has three levels: Easy is relaxed and makes mistakes, Medium thinks a few moves ahead, and Hard searches deep and rarely falls for a trap. Choose who moves first – the first player has an advantage. In 2 Players mode you and a friend take turns on the same device. Your score is kept for the whole visit.

Connect 4 strategy tips

• Take the center column: it is part of more winning lines than any other column.
• Block three in a row as soon as you see it, and watch the diagonals – they are the easiest threats to miss.
• Build two threats at once. Your opponent can only block one of them.
• Never fill the space directly below your opponent’s winning square.
• Count the rows: the player who moves first gets the most out of threats on odd rows (1, 3 and 5 from the bottom).
