A play-by-post game (often shorted to PbP) is an online text-based game in which players interact with each other and a predefined environment via text. It is a subset of the online role-playing community which caters to both gamers and creative writers. PbP games may be based on other role-playing games, non-game fiction including books, television and movies, or board games and other table topgames. This activity is closely related to both interactive fiction and collaborative writing.

Games vary in the degree to which the setting is established; some go as far as to include a virtual "world" to roleplay in, while others allow players to improvise the setting as they progress. Settings may be derived from novels, TV shows or movies (often resulting in collaborative fan-fiction) or may be unique to the game.
Play-by-post games are frequently written in the third person perspective due to the fact that multiple players must share each scene, each with his or her character as the focus of attention. Common online game terms such as OOC (Out of character) or OOG (Out of Game) are used to differentiate in-character from personal posting.
The opening message or post of each scene typically lays down the scenario and describes a scene, or continues from a previously started scene. Threads then become an ongoing story in which players periodically advance the plot by reading the latest reply and then responding with what their character does and how the environment changes in response. These replies are often open-ended so that other players can continue.
