How people play
Two players take turns dropping a disc into one of the columns. The disc falls to the lowest empty space. The first player to line up three of their discs across, down or diagonally wins. If the board fills first, it is a draw.
Common challenges
- Double threatsWith only three needed, two open threats appear fast. Spot them before your opponent builds one.
- Playing under a threatDropping into a column can give your rival the space right above it. Check what your move sets up.
- Ignoring the centreCentre discs join the most lines. Players who start on the edge usually end up defending.

- Pattern recognitionWins come from spotting shapes, threats, and repeats early.
