An introduction to game theory, complete with step-by-step tools and detailed examples.     This book offers condensed breakdowns of game-theory concepts. Specifically, this textbook provides "tools" or "recipes" to solve different classes of games.   Game Theory  presents the information as plainly and clearly as possible. Every chapter begins with the main definitions and concepts before diving into the applications to different settings across economics, business, and other social sciences. Chapters walk readers through algebraic steps and simplifications. This makes the text accessible for undergraduate and Masters-level students in economics and finance. Paired with the exercises published on the accompanying website, students will improve both their theoretical and practical understandings of game theory.   Readers will walk away from this book understanding complete and incomplete information models as well as signaling games.
