Connect Four
Connect Four is a classic two-player game. Red moves first; Yellow responds.
On your turn you choose a column. Your disc falls by gravity to the lowest free cell of that column — you never choose the row.
The first player to line up four discs in a row — horizontal, vertical or diagonal — wins immediately.
If the board fills up with no line of four, it is a draw.
Boards: 6×7 (classic) (6 rows × 7 columns, the classic) · 7×8 (large) (7 rows × 8 columns, more room).
You pick the column; the disc falls to the bottom. Four red discs in a row complete a horizontal line — and win.
