The game rules are divided into two books, the Player’s Guide and Narrator’s Guide. The Player’s Guide is a free ebook, formated to be viewed on a wide variety of devices. You may need an eReader app but as an ebook you have more flexibility than a PDF. You can adjust the font size and the text will flow to fit the size of your screen. Please let me know how it is working for you. Getting the formatting to work well on any device is a daunting task!
