This is a hints, tips, reviews, and strategy guide to Game Boy games, and initially also a look at stand alone hand held games made by Acclaim Entertainment and Konami. There were 41 games reviewed in the books main section, many of which have a gray-scale screenshot. There were 21 previews for new games some of which had screenshots. Two further editions were released a '2nd Edition' which dropped the reviews of other handheld games and had 55 reviews all with a screenshot except 'Paperboy' and 9 Mini-Hints. Then a '3rd Edition' which ended up with 79 reviews and 23 Mini-Hints. Each of the main games reviewed had some of the following sections for each game; 'Control Pad', 'Basic Moves', 'Playing the Game', 'Scoring', 'Screen Display', and other related sections followed by the strategies, tips, passwords, cheat codes and the like. The '2nd Edition also included a rating on these game's " Graphics", "Response", "Fun", Ultimate Score", then for the '3rd Edition' two of these were expanded to include 'Graphics/Sound', Response/Playability', listing and added a one sentence overview, at the start of each game review. The first two editions of the book were in large trade paperback size, while the '3rd Edition' was released in a small mass market size.
