This is a lengthy variant, but if you enjoyed the original, trust me it is worth the time to read.
You could add more variants to the game depending on how capable the group is.
The Sheriff Variant
Choose a certain card to represent the town sheriff. Each time that the Town “sleeps,” the facilitator of the game can ask the Sheriff only to raise his/her head. The Sheriff then can ask the facilitator, secretly and silently, if a certain one person is in the mob. The Facilitator answers the sheriff acordingly. (The facilitator knows who the mob members and towns people are because at the begining of the game he asks the mob members to eliminate someone) The facilitator tells the sheriff to put his/her head down, then tells the mob to raise their heads and eliminate someone. The next day, the sheriff tries to tell the towns people his/her findings without being to obvious as to let the mob know that he/she is the sheriff so that the mob won’t eliminate the sheriff next round.
