Play Connect Four online
Connect Four is a two-player strategy game about building a line while stopping your opponent from doing the same. Discs fall down a column, so you cannot place one anywhere you like. I like how a simple turn can create a threat several moves later, especially when both players are watching the centre.
How to play
- Open Connect Four and choose an online friend, solo play or the same-phone option.
- Choose a column with room for another disc. Your disc falls to its lowest free space.
- Wait for the other player to drop a disc, then inspect the changed board.
- Look for four connected discs horizontally, vertically or diagonally, and block immediate threats.
- Complete your own line of four before your opponent does.
Modes and a useful starting point
Available modes: solo play, online with a friend, versus play, same-phone play.
On a keyboard, keys 1 to 7 drop a disc into the corresponding column. The Hint button suggests a move and explains why. Before building a new line, check whether your opponent can win on the next turn. A promising attack is only useful if you survive their reply.
