Tic-Tac-Toe

Well, over the weekend I ran into a lot of gamers and it kind of made me think of a low tech thing to do. What better than Tic-Tac Toe. Put it in places where people spend time, hence elevators and the bathroom. The question that I'm wondering is if people don't play games straight through then will every single one be a cat's game? Or will someone purposelly lose?
