About Connect Four
Connect Four is the two-player disc-dropping strategy game where you race to line up four of your colour in a row. Players take turns dropping discs into a vertical grid, and each disc falls to the lowest free slot in its column.
The first to connect four discs — horizontally, vertically or diagonally — wins. It looks casual, but strong play is all about setting up multiple threats at once and reading your opponent's plans before they land the winning move.
How to Play Connect Four
- Choose a column to drop your coloured disc into.
- The disc falls to the lowest available slot in that column.
- Players alternate turns dropping their discs.
- Connect four of your colour in a line to win.
- Block your opponent when they line up three in a row.

Winning Tips & Strategy
- Play the centre column early — it feeds the most possible winning lines.
- Always block the instant your opponent has three in a row.
- Create a 'double threat' so a single block cannot stop both lines.
- Think about the row above — don't hand your opponent a winning drop.
- Watch the diagonals; they are the lines players miss most often.
