Dozens of special roles are available to help both the villagers and the werewolves achieve their goals.

][2] One Night Ultimate Werewolf,[6] published by Bézier Games, is based on a similar concept to Ultimate Werewolf although the differences are significant enough to change the style and feel of gameplay.

[9] One Night Ultimate Werewolf also provides a smartphone app taking the role of the moderator, available on both iOS and Android platforms.

The One Night smartphone app enables players to include roles from any edition in a single game and adjusts the moderator script accordingly.

In Ultimate Werewolf, the Doppelgänger can then take action in the subsequent night phases of the game.

[13] One Night Ultimate Werewolf has been well received by critics as a shorter alternative to the original Werewolf game, that also fixes the problem of player elimination and makes the game more interesting for the villager players.
