Playing games is not just for children. In fact, playing games can make the learning process easier and more fun for adult students as well, for example, in language courses. Despite this success in teaching other subjects, microwave engineering education rarely employs games for learning. However, during the past few years, we have designed and optimized a game that is suitable for senior undergraduates or first-year graduate students in an introductory microwave engineering course. The game is welcomed by our students and indeed makes both teaching and learning more interesting. In this article, I introduce the design philosophy of the game and explain how to play it.
