Publisher's blurb:
A unique, universal-genre role-playing game that fits on a bookmark!
Don't let its small size fool you! This "One Roll to Rule Them All™" polyhedral dice system is robust, using a simple 1-10 scale for action difficulty, and combining success, damage, and character improvement in a single action roll!
With character design in literally a minute, it's great for introducing new players to the hobby. Just choose a name, invent an occupation, rate four stats, and you're ready to go!
And while perfect for one-shots and convention pick-up play, it can also support mini-campaigns of a half-dozen adventures or more with the same characters.
Yes, that's a lot to claim for an RPG on a bookmark, but the designer is known around the world for unique approaches to odds-based dice mechanics. How much are you really risking for $4.99?
