One Week Ultimate Werewolf takes the gameplay of One Night Ultimate Werewolf and twists it, with more tension as you venture into the special rooms of Ludwig Castle. Each room gives a special power, and those powers are needed to figuring out the mystery of who among you is a werewolf. Roles can be viewed and switched multiple times before all is said and done, then the final vote takes place.

As in One Night Ultimate Werewolf, your objective is to figure out the secret roles of your opponents as well as your own role by the end of the game. Each day, you enter a different room with a different ability, and each night you interact with the other players in that room. In addition to the 3-7 players, 3 staff members walk the castle, and each of them also has a secret role. After one weeks investigation (which should take about 45 minutes), it all comes down to a vote. If you're a werewolf, you're attempting to remain undiscovered. If you're a villager, you're attempting to find those sneaky werewolves. And if you're a Tanner, well, you're trying to get caught!

One Week Ultimate Werewolf comes with more than a dozen different rooms. You play with just a couple each game, making each game different.
