Cthulhu in the House is a game of bluffing and deduction for the whole family. Each player secretly owns two of the twelve characters in the house; and each character starts in a different room of the house. On a turn; a player either moves any character that is alone in a room into an adjacent room or starts a fight in a room that contains at least two characters. Well; it's not much of a fight really; as the player removes one character from the room and places it in a line with other removed characters. Once a single character remains; the round ends. The first two characters removed are worth zero points; while the third through eleventh characters are worth 1-9 points; the character that remains in the house is worth ten points. Each player collects points only for his most valuable character.
Cthulhu in the House differs from its predecessor; Rumble in the House; thanks to two types of tokens that are placed in some locations. One type switches a character into a different room; possibly causing a fight in the process; while another type is an abyss; which switches which character would be removed from play.
The player with the most points after three rounds wins.
