A game about ninjas trying to assassinate each other as they move throughout a house by laying traps. Uses a mechanic whereby the player must remember which traps they put where in order to activate them. Cards represent rooms/areas of a house which players may use to move about the house or play as hidden traps to activate when another player enters the trapped area. As the game progresses, it becomes more difficult to remember where traps were placed and it can even be possible for a player to trap themselves by mistake. If a player is trapped three times, they are eliminated.
