A collection of guidelines on hosting contests is also available.
Here are the rules specific to the "C" league:
- Can have any level of difficulty. As easy as an "A" or harder than a "B".
- Must have special rules of some kind. No "standard rules apply". eg: "quickest wins", "the armadillo must pass through all of the hoops" or "exactly four rubbers, two ropes and one elastic should be used".
- The special rules for scoring must be objectively verifiable, and not a
matter of personal opinion. Eg: "Most ingenious solution wins" is not allowed (those rules should be kept for the Design Competitions). - If the rules include special winning conditions, Light and dark medals are awarded with respect to these new conditions; the best light solution will win the light medal, and the best dark solution will win a dark medal if it is 'better' than the best light solution. Note: Any 'dark' constructions which the special rules say you must have in your solutions are considered OK and do not make your solution dark. Eg: if the rules say you need to use a force paddle, then using 1 is still light, but using 2 would be dark.
