Shadow Riddler is a multiplayer role-playing game in which players take on different roles and reason, vote, and more to find out who the werewolves are and destroy them.
Before the game begins, each player is randomly selected a character, including guards, civilians, seers, vampires, and more. Werewolves and vampires are the villainous characters in the game, who have to carry out assassinations on other players at night, while other players have to try their best to find out the werewolves and destroy them.
The game is divided into two phases: daytime and nighttime. During the day, reasoning can be used to try to figure out who the werewolves are. During the night, the werewolves will choose a target to assassinate while the other players try to protect themselves from being assassinated.
