One out of three players randomly gets assigned a special role: murderer, also known as an impostor. This player gets an amazon, thus allowing them to strike down players much more efficiently.
Every single player starts out with a different royal piece, with royal captures being impossible due to Fatal Capture - as such the players have to free the grasshoppers and try to checkmate the murderer/impostor and leave out for the hill of that player.
If a player knows who will get mated next, they may rush for the hill blocked with pawns of that player and then obtain a promotion on that hill. Respectively, the murderer and the peasants may choose to not checkmate each other immediately, due to the reasons of someone suspecting a player or guarding the hill.
