Connect Four is the two-player strategy classic where dropping one disc can change everything — and it's free right here in your browser. Take turns sliding red and yellow discs into a 7-column grid, and race to be the first to line up four of yours horizontally, vertically, or diagonally. Challenge the built-in AI or pass the screen to a friend. No downloads, no accounts — just click NEW GAME and drop your first disc.
The board is a vertical grid of seven columns and six rows. On your turn, click or tap a column and your disc drops to the lowest empty slot in that column. Play alternates between Red (Player 1) and Yellow (Player 2), and the first player to connect four of their own discs in a row wins the round. If the board fills up with no four-in-a-row, the round is a draw. In one-player mode, Yellow is played by an AI that thinks before it moves.
Desktop: click any column on the board to drop your disc there.
Mobile: tap the column you want — the disc drops straight into the lowest open slot.
This version tracks your match record rather than points: Red wins, Yellow wins, and draws are all counted separately and saved in your browser. A match-history list shows the outcome and mode of your last several rounds, and the running tally is restored every time you come back — so you always know who's ahead in the series.
Connect Four was first sold by Milton Bradley in 1974 and quickly became a family favorite, with a famous mathematical result showing that perfect play from the first player is always a win. This browser version keeps the simple, instantly readable rules while adding a strategic AI opponent and win/draw tracking that persists locally. It's one of 20 free classic games on ZenClick, ready on any phone, tablet, or desktop.
