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 5 (2021-2022) includes Uncanny Rally - with Chris McDowall (Electric Bastionland, Into the Odd), Big Bang Superstars - with Nathan Blades (Shadow Operations, Arcana Corps), Cluedont - with Chloe Mashiter (Alongame, Time Heist), Himbo Treasure Hunt - with Sasha Sienna (Odd Jobs), Arlecchinos Eleven - with Daniel Lavery (The Toast, The Chatner, Texts from Jane Eyre), Heartswood - with Sarah Gordon (Vicious Creatures), Lexinomicon - with Becky Annison (Bite Marks, Lovecraftesque), Wreck The Halls - with Thryn Henderson (Ryne, Small Town Skeletons, Jolene), The Rules of the Deep - with Jay Dragon (Wanderhome, Yazebas Bed and Breakfast), Captain Swanhands - with Jeeyon Shim (The Longest Rest, The Snow Queen), Bird Crimes - with Xalavier Nelson (Space Warlord Organ Trading Simulator, Hypnospace Outlaw, An Airport For Aliens Currently Run By Dogs), and Death Was The Only Road Out Of Town - with Alex Roberts (For the Queen, Star Crossed).
