Numbic is a clever board game for two or against the computer, where you have to line up four different symbols horizontally, vertically or diagonally. Sounds familiar and simple, but in Numbic it's hard as hell: because you're playing on two different boards, and every move you make also results in a move on your opponent's board. So not only do you have to keep an eye on your own position, but you also have to prevent yourself from unintentionally helping your opponent win.
