In 2016, Grant Howitt decided flippantly to write a one-page roleplaying game every month and release it for free online. Little did he know that the barely-intelligible pen-and-ink scratches he turned out would go on to define his career, and the shape of roleplaying games, for years to come. Played by thousands of people all over the world, Grant's one-page games run the gamut from strange to silly, daft to deadly serious, and powerfully original to potentially copyright-infringing.

Each volume contains (at least!) 13 games in their original single-page format, complete with SECRET BACK PAGE material for every game that's never been released online. Plus, where relevant, the longer games Grant and his collaborators have released are printed in full-color, saddle-stitched booklets. Each game has been written, illustrated (sorry) and laid out entirely by Grant, unless someone else helped him, in which case it says so.

As of 2024, all these volumes come in US Letter size, in a sturdy cardboard folder with a spine. Volume 3 (2019-2020) includes Goat Crashers, Wake Kobold Endeavour, Beautiful Space Pirates in: THE GALAXY'S MOST DANGEROUS FUNERAL, This Is Not A Place Of Honour, Dungeonscrawl: The Palace of the Briar Prince, Sexy Battle Wizards, The Witch House, Reverse Beastmaster, Be Prepared, Sad Vampire Boyfriend, Sean's Bean in: A VERY NORTHERN CHRISTMAS, and What I Did On My Summer Holidays.
