As the title suggests, this is not one game, but five. They are all based on the same system and are all sold in a single book.
The game system of all the games is the Narrative Cage Match. In this system, players take turns in adding one sentence to the story that must mention their own character and may mention only one other character. The players may also add supporting characters (NPCs) to the story. The players use beads (or jellybeans or coins) for challenging plot elements of other players, or for bribing other players. A scoring system determines the winner of the game.
There are five different scenarios to chose from.
