2017 marks the ten-year anniversary of the GameTek segment on the Dice Tower podcast. Connecting games to math, science, and psychology, GameTek has grown to be one of the most popular parts of the show. This volume commemorates the anniversary with a collection of over seventy of the best segments, many with annotations and illustrations. With chapters on everything from Rock, Paper, Scissors to the Prisoner's Dilemma to Player Engagement to Quasicrystals to Buddha's Forbidden Games, GameTek is sure to delight not just game designers and players, but anyone who wants to learn about the world from a new perspective. Sections: • Game Theory • Math • Psychology • Science • Game Mechanics • Psychology Games • History… From the first time I heard it, the GameTek segment in The Dice Tower podcast became my favorite part of the show. Listening to Geoff is like going to your favorite lesson with your favorite teacher. He teaches about games (yay!) and does it in a very interesting way with lots of examples. He does amazing stuff. He knows about the construction of games, he knows the theory, he knows all that stuff behind the scenes that we gamers do not see when just playing a game and having fun.
