In this environmental game, players try to prevent greenland from being covered with mud. In his turn, a player reveals a situation card that shows a positive or negative environmental behaviour. In the case of negative behaviour, the bad figure "Schmutzich" is moved towards a target field, in the case of positive behaviour, the good figure "Knud" may be moved towards the target field. In addition, the player rolls the dice and can move his own figure or "Knud" towards the target field. If "Schmutzich" reaches the target field first, mud is placed on grassland, if "Knud" and a player arrive before "Schmutzich", a rainbow piece is placed. The players win together if they manage to lay 4 rainbow pieces. The players lose if "Schmutzich" was able to lay 4 mud pieces. —user summary
