Book Review: A Theory of Fun for Game Design

Book Review: A Theory of Fun for Game Design
Last Updated on: November 2, 2026

Theory of Fun for Game DesignTheory of Fun for Game Design* is a deceptively educational book on the topic of fun and game design. Less on game design and more on fun. In 244 pages, Raph Koster provides his definition of fun and outlines the importance of games for learning. Koster explains we find learning fun. Specifically, we enjoy problem-solving and skills development. Games serve as a magnificent vehicle for both, and people have used them since the beginning of time to pass on survival skills, but times have changed.

Koster is a game designer and was responsible for developing the Ultima Online series and the Star Wars Galaxies series. He was driven to write this book because he was trying to understand why his kids found a game fun one moment and boring the next. He determined it was all about recognizing and mastering the game patterns. Once they figured out the game and solved the problems making up the essence of the game, they then became bored. We follow the same pattern.

Why Patterns Make Games Fun

Across twelve chapters, an introduction, and an epilogue, Koster provides stories and details about what makes games fun. He leverages all his experience as a game designer and fun-maker. Koster looks at the topic from several lenses. In chapter 2, he points out all the different definitions focusing on games. He stresses no one can agree on a definition, and all the definitions lack the element of fun.

Koster also introduces the subject of patterns. He explains we try to find patterns in everything to simplify problems we are trying to solve. Once we discover the patterns, we then use them in processes. The hunt for patterns and the practice of processes make games fun. Once we have mastered the task and pattern, we become bored. We “grok” something when we have mastered the pattern to where it is intuitive. A game like tic-tac-toe is easy to grok because the pattern is easy to identify. However, a game like chess is harder to master because there are infinite patterns.

What Games Teach Us

Koster stresses games teach us survival skills. Historically, we started with running, throwing, and jumping games because our survival depended on it. Many of the games on the market have similar core mechanics relating to survival skills such as aiming, timing, hunting, territory, and projecting power. Koster points out we must develop new games relating to survival skills that we need in these times such as understanding issues of social responsibility and working as a member of the global community.

Koster also touches on Gardner’s multiple intelligences and points out that people gravitate towards different games because of the patterns they recognize. If they do not recognize a pattern, they then consider it noise. Some people prefer physical games, while others prefer role-playing games, and still others enjoy word games. We need to consider this when making educational games.

An Engaging Read for Educators and Game Designers

Koster wrote this book conversationally, yet it contains so many details that it makes you want to find out more. The book presents prose on all the even pages, while the author includes insightful illustrations on all the odd pages that readers should contemplate. Each page provides a wealth of valuable information. Reading the book was like peeling back the layers of an onion; there was always something new to explore. The last section of the book contained detailed notes that helped define terms and concepts.

Someone recommended Theory of Fun for Game Design to me, and I am glad I read it. This is another book worth putting on your bookshelf if you are interested in gaming and gamification.

“Fun is just another word for learning” (Koster, 2005, p. 46).

    People seem to be more comfortable with what they know, therefore, they are absolutely drawn to patterns…. there are more big words in this reading that i do not know. I hope that I get used to the big words being used in all of the texts that I am reading so that I get used to and drawn to the pattern of good writing, and can use verbiage in my own writing. This was an enjoyable piece of literature, although I did become bored,
