For this achievement, you'll need to play and win a game of Connect 4x4 Remix. Remix is a little different form original. To win this game you'll need to get at least 3 Connect 4s to win. It is best to use 4 controllers for this achievement so that there are no AI players to screw things up. Before you start the game, make sure to go into settings and change it so game end is 25 points. When it is the other controller's turn, just make sure they don't get a connect 4 and you'll have this achievement in no time!
