About the Book

Discover how to create online "Hidden Picture" games using the methods in this single chapter from the Phaser Game Starter Kit Collection. When you finish this chapter, you will have a production pipeline ready to create as many different "hidden object" games as your imagination can dream of!

You'll also get bonus content, download examples, game variations, and source code references on how to do every single thing in this game design workbook, so you can copy and paste any examples into your own productions and then modify those resources for your own purposes. General Game Licenses are included in the purchased book.

I would like to guide you in creating several types of "Hidden Picture Puzzle" game mechanics. We will use the game mechanics, mechanisms and the development methods discussed in Phaser Game Prototypes. By the end of this workbook, you should have a fully functional "Hidden Objects" game - not just a copy of my game, but your very own product using your own gaming assets. There is a supporting website where you can download the bonus content included with your workbook's purchase.  

This extraordinarily comprehensive guide will teach you how to: 

- Use the Phaser JS Gaming Framework either v2.x.x or v3.16+.

- How to integrate "Hidden Object" game mechanics into other game genres such as Detective adventure and spy stories!

- Use your game as a "Progressive Web Application" or "Single Page Web Application" for any device.

- Analyze current business demand for this game's genre, how and where to deploy it.

- Automatically generate various game board features.
