A minimalist hack of Dungeon World with character traits inspired by Risus, Rydu is designed to be compatible with *W games, to be playable solo, and to fit in a pocket. Print it out, fold it up, slip a few blank pages for maps into the pocket, grab a pencil stub and four d6s, and you’re set. You don’t even need friends.
Rydu is compatible with Apocalypse-style Moves, but plays fast solo with a minimum of gear and prep. There’s no explicit oracle, but plenty of Moves to keep things moving. So use your favorite or use “roll a d6, high is good, low is bad”.
The core mechanic is pool-based, pick one, but uses roughly the same odds and outcome distribution as you’d expect from a game powered by the Apocalypse. It’s in pocketmod format, for dungeoneering on the go.
