While WFW has rules, it's not fair enough, since one rule of two is never noticed nor said. This rule is Weapon On Space (WOS). The rule is pretty simple, players have to fire weapons and use utilities from their respective spaces (for example, Low Gravity on Low Gravity space, Petrol Bomb on Petrol Bomb space, Old Woman on Old Woman space, etc). Players cannot use weapons from other spaces on the space they are standing on nor durning jumping from one space to another (only the weapon from the last standing space can be used, for example, Dynamite can be used durning jumps from Dynamite spaces unti the worm lands on any other space, etc).
