Ted Alspach's Werewords

In Werewords, players guess a secret word by asking "yes" or "no" questions. Figure out the magic word before time is up, and you win! However, one of the players is secretly a werewolf who is not only working against you, but also knows the word. If you don't guess the word in time, you can still win by identifying the werewolf! To help you out, one player is the Seer, who knows the word but must not to be too obvious when helping you figure it out; if the word is guessed, the werewolf can pull out a win by identifying the Seer!
