Game Logic is useful for STEM teachers and anyone interested in the history of games and how to create them. Six chapters delve into various games and provide a great foundation for understanding the variety of board and tabletop games. 31 pages of activities complement the text which is full of helpful information and advice. Activities vary from making your own cards with block printing, comparing modern board games to mobile app versions, modifying role-playing games, and designing a legacy game. Books, magazines, and web sites are suggested. A table of contents, a timeline, and an index are included. QR codes are abundant. Game Logic is part of Nomad Press' Build it Yourself series, which is the most practical STEM series I have used for third through eighth graders. Strongly recommended for elementary and junior high school students.
