Build your own one-page solo games
This one-page document is both a guide and a template for crafting your own Second Guess System games, the engine behind One White Eye, The Date, Hard Case, Lord of Terror and more.
The core idea: a d20 and twenty prompts, and the game won’t stop you from rolling the same prompt twice. Instead, it twists what happens. Everyone lies, to each other and to themselves, so each time a prompt comes back around you must admit something you lied about before. Add a quick d6 roll and an escalating Dread tracker you must beat or succumb to, and you have a game.
Dozens of designers have already used the SRD to publish their own Second Guess games.
