This chapter is all about games. But the games I discuss are not the multi-million-dollar video blockbusters that are currently saturating the marketplace. Instead, they are the much simpler games that have been around for a very long time; some for thousands of years. But even in these simple games, AI has had an impact. The games discussed in this chapter traditionally involve two human opponents, but the modern varieties involve one human playing against a computer. That’s where the AI comes in: to provide some randomness and competition to the human player such that playing the game does not quickly become boring and trivial.
