Your turn. Pick a column.
How to play Drop four
Take turns dropping coloured discs into a seven column grid. Discs fall to the lowest empty spot in the column you pick. Your goal is to line up four of your discs in a row, vertically, horizontally or diagonally. The bot plays the other colour and tries to do the same. First to four in a row wins. If the grid fills with no winner, the game is a draw.
Tips
- Aim for the centre column on your first move, more lines run through it
- Watch for diagonal threats, they are the easiest to miss
- If you can block a three in a row, do it before going for your own win
- Stack your own pieces in different columns to set up multiple threats
About Drop four
Connect Four was sold by Milton Bradley in 1974 in plastic with bright yellow and red discs. Mathematicians solved it in the 1980s: the first player can always win with perfect play, starting in the centre. Most humans never play perfectly, which is exactly why it is still fun. Our bot plays at a friendly level. Tough enough to push you, soft enough that beginners can still pull off a real win.
