Four in a Row Game Online🔴Connect Four

How to play Connect Four

Connect Four is played on a grid of 7 columns and 6 rows. Players take turns dropping a disc into a column, where it falls to the lowest empty space. Red moves first. Line up four of your discs horizontally, vertically or diagonally to win. If all 42 spaces fill without a line, it's a draw.

Click or tap a column, or press 1 to 7. Choose Easy AI, Hard AI or 2 Players above the board. Against the AI you play Red and start. Easy AI takes wins and blocks yours when it sees them but otherwise plays loosely, while Hard AI looks five moves ahead. You can also play a friend online with a room code.

Tips

• ▸Start in the middle column. More lines of four pass through the centre than any other column.
• ▸Before each move, check whether your disc lets your opponent complete four in the space above it.
• ▸Aim for two threats at once. Your opponent can only block one.
• ▸Watch which row a threat is on. A winning space that can't be filled yet often decides the endgame.
