Can you get four in a row before your opponent?
Take on the challenge to see if you can create a bot that plays a 'perfect' game.
Each player chooses which game style they wish to play.
When two players have requested the same game style, they are matched by the server and a game begins.
Take it in turns to place a counter in one of the rows.
Be the first to make a line of counters of the winning length either horizontally, vertically or diagonally.
