In most games, there are things you don't know. You don't know what number will come up when you roll the die. You don't know what cards your opponent is holding, or which ones you'll draw next.

These so-called "perfect information" games are very attractive to some players, but not to all. Join us as we look more closely at what it means when the players know it all.
