Rule

Rules are unofficial requirements set by players of certain unofficial Game Styles. These rules are generally implemented to ban methods of play that have been deemed too cheap and unfair to allow, or to regulate a game style with restrictions not implementable by only the game mechanics, such as Alt+F4.

Example rules

 * In the Fort gamestyle, players are required to put their team's Worms somewhere on the fort they claimed, and not on any other fort.
 * Racing game styles require players to place all Worms on the starting location area, as it is blatant cheating and an unfair advantage to start further along on the course than the start. These styles also require the players to take the intended course from "Start to Finish" meaning they may not take any shortcuts not intended by the course creators.

Penalties for Rule Violators
Players who violate the rules are to undergo a punishment rule depending on the gamestyle. An example of a punishment rule is that a violating player must use Skip Go to lose a turn.

Kill the Cow
This rule is used as a last resort to punish players who clearly either are cheating by violating the rules on purpose, or are not following the correct punishment rules because they don't know the Game Style rules. Players are, under this rule, able to freely kill off cheaters in this not needing to follow the normal rules of the game style to do so.
