Play Connect Four against the computer

Challenge the computer to connect four first. Tap a column to drop a piece. Connect four horizontally, vertically, or diagonally.

How to play

1. Take turns with the computer. Tap a column to drop your piece into its lowest empty slot.
2. You cannot play in a full column; wait while the computer takes its turn.
3. The first to connect four matching pieces horizontally, vertically, or diagonally wins; a full board without a line is a draw.
