- Not to be confused with rules as interpreted.
Rules as intended (RAI) are rules that represent the design goals of a role-playing game's designer, but which may differ from the rules as written (in actual rulebooks) because of error (e.g. typos), miscommunication, or misunderstanding.
Rules as intended may be converted into rules as written by the release of errata or updated versions of rulebooks. More often, rules as intended are gathered through interviews with designers or comments on social media, then passed around online through word of mouth.
In some cases, the choice for players to use rules as written or stated rules as intended has been a topic of debate in RPG communities.
