yup it's tik tak toe.....I do remember seeing one of these made out of relays in a museum when I was a kid. Can't remember which museum though. I'd start by numbering the squares zero through 8 and using two bits to describe the state of each square from the set {X, O, Blank}. It is known that the player who goes first is the only player who can win unless the opponent makes a mistake. Now it is a matter of chosing a strategy to prevent losing or in case of an opponents mistake secure the win
Perhaps you could post up details of what you have done so far and then we could give you some pointers. Otherwise this thread might as well be closed.guys i also need stripboard layout for that circuit...
