A new version of the Regulations and Guidelines is going into effect April 18th, 2016.

The current Regulations are always available from https://www.worldcubeassociation.org/regulations/

For an exact list of all changes from 2015 to 2016, view the differences on GitHub.

Summary of changes:

  • The penalty for putting the puzzle outside the mat after the inspection phase and before starting the timer was defined as +2. (#343 | 347)

  • Scramble sequences should be used in a maximum time frame of 2 hours. (#295 | 342)

  • It has been clarified that cumulative time limits can be defined for a combination of events. (#296 | 334)

  • Generation 4 Pro Timers may be used for time measurement. (no issue | 333)

  • Clock pins must not be identifiable from any other pin on the same side and the solved state of Clock is not affected by pin caps missing after the solve. (#189 | 329)

  • It was explicitly clarified that judges in Fewest Moves are allowed to compete. (#165 | 329)

  • It was clarified that every part of the body may be used during solves (except in Feet and One-Handed Solving). (#300 | 324)

  • The minimum size of a mat was defined as 30 cm (left to right) by 25 cm (front to back). (#304 | 335)

  • It is now recommended that extra attempts should be done right after the attempt they replace. (no issue | 341)

  • The maximum number of rounds in an event is now defined by the number of competitors in every round (instead of the number of competitors in the event). (#314 | 346)

  • All types of stickers are allowed in Fewest Moves (the word "coloured" was removed). (#68 | 329)

  • The tab used for alignment of the layers in Square-1 may be removed during the attempt if the competitor forgot to remove it in the inspection phase. (#315 | 323)

  • It has been clarified that the number of competitors may be limited per competition and not only per event. (#311 and #325 | #327)

  • A clarification for Fewest Moves solutions that are similar to the inverse of the scramble sequence has been added. (#344 | 348)

  • In case of a cumulative time limit, the result of each remaining attempt in the round is recorded as DNS after a competitor reaches the time limit. (#303 | 353)

Announced by Laura Ohrndorf on

TNoodle-WCA-0.11.1 is now available from https://www.worldcubeassociation.org/regulations/scrambles

The following change has been made since TNoodle 0.10.0:

  • The colour scheme of Megaminx and Square-1 has been changed to the ones widely used today.
  • The scramble generation process for Fewest Moves has been changed. Fewest Moves scrambles are now longer and the scramble sequence is no longer directly related to the puzzle state they produce. In particular, all scramble sequences for Fewest Moves are padded with the moves "R' U' F" at the beginning and the end.

Please remember that official competitions must use the current version of the official scramble program. This is always available from: https://www.worldcubeassociation.org/regulations/scrambles

A new version of the Regulations and Guidelines is going into effect July 1, 2015. The scramble program will be updated soon to accommodate these changes.

The current Regulations are always available from https://www.worldcubeassociation.org/regulations/

For an exact list of changes from 2014 to 2015, view differences on GitHub.

Summary of changes:

  • Stickerless puzzles are permitted. ( #177 | 580ea35, a4e289c)
  • Competitors may be given tentative extra attempts during incidents with an unclear outcome. ( #245 | dd7527e)
  • A recommended standard procedure for giving extra attempts is described. ( #228 | 45cf5a5)
  • Competitors may DNS an individually scheduled attempt and still be eligible for future attempts. ( #263 | 3711345)
  • Competitors must not compete with the intent of intentionally poor results or a DNF. ( #203, #225 | ba0308c)
  • Newer competitors may be given an extra attempt for their inexperience in a competition. This only allows a full extra attempt, and does not allow ignoring individual penalties. ( #251 | 65c3e7e)
  • Organizers may enforce the use of an object to prevent a Square-1 from being altered in transport to the timing station. If used, competitors must remove this object during inspection, and the organization team must make it clear that such a tab is being used. ( #192 | 3dc5d83, 1946e9a)
  • It has been explicitly clarified that the Board has the ability to modify results when the WCA Regulations have not been observed. ( #262 | 5b002e0)
  • O-rings and padded battery compartments for timers are strongly recommended. ( #235, #243 | 67ab825)
  • Competitors must not reset the timer until the end of the attempt, and it has been explicitly clarified that judges must not write down times from memory. ( #206, #218, #222, #230 | e5a4879, fb14ded)
  • Competitors are allowed to use a clock during FMC to keep track of time. ( #217 | afea552)
  • It has been explicitly clarified that competitors don’t need to turn in their solution on an FMC sheet ( #215 | a0382d7).
  • The organization team may require stronger measures to ensure correct scrambles. ( #214 | 9d7c310)
  • Pyraminx must require at least 6 moves to solve (rather than 7), matching the number of moves in the current Pyraminx world record solution. ( #213 | 49c8503)
  • Cameras are explicitly permitted as long as the competitor is not interacting with them ( #178 | c24c70d, 04cdc58, 8699359).
  • It has been explicitly clarified that not resetting the timer before an attempt is the judge’s fault, and results in an extra attempt. ( #260 | 52a4a03)
  • The starting orientation of the clock does not specify a certain side of the clock for scrambling. ( #269 | 3cd54d8)
  • Using video evidence to recover a time that a competitor reset is not allowed. ( #270 | 718f5a0)
  • Exceptions given to competitors with visual disabilites have been further described. ( #271 | a9693fb)
  • The use of the Stackmat mat in long events has been explicitly clarified. ( #273 | 4529c5b)
