Latest textual revision: July 3, 2009
To make the regulations easier to read we use 'he' where the reader should read 'she or he'.
The use of the words 'must', 'must not', 'should', 'should not' and 'may' comply with RFC 2119

|9e)||New official events may be added each calendar year, and existing official events may be removed.
9e4) Other events may be held during a competition, but will be unofficial and therefore not part of the official results of the competition.
- 9e1) The decision to add or remove an event is made by the WCA Board, based on feedback by the community.
|9f)||The results of a round are measured as follows:
- 9f1) All timed results under 10 minutes, and corresponding averages/means are measured in hundredths of a second, with averages/means rounded to the nearest hundredth of a second (x.004 becomes x.00, x.005 becomes x.01).
- 9f2) All timed results over 10 minutes, and corresponding averages/means are measured in seconds, with averages/means rounded to the nearest second (x.4 becomes x, x.5 becomes x+1).
- 9f3) All counted results and averages/means are measured in natural numbers, with averages/means rounded to the nearest tenth (x.04 becomes x.0, x.05 becomes x.1).
- 9f4) DNF (Did Not Finish) is the result if the solve was disqualified or unfinished.
- 9f5) DNS (Did Not Start) is the result if a competitor skipped an attempt in a round.
- 9f6) In 'Best of x' rounds competitors get x (<= 3) attempts, with the best attempt counting. There may be a combined time limit, example: 30 minutes for 'Best of 1' or 'Best of 2'.
- 9f7) In 'Best of x' rounds a DNF or DNS is the worst result of a competitor, if all results are DNF and/or DNS the best result of the competitor is DNF.
- 9f8) In 'Average of 5' rounds competitors get 5 attempts. Of these 5 attempts, the best and worst attempt are removed, with the mean of the remaining 3 attempts counting.
- 9f9) In 'Average of 5' rounds one DNF or DNS is counted as the worst result, with more than one DNF and/or DNS the average is DNF.
- 9f10) In 'Mean of 3' rounds competitors get 3 attempts, with the mean of the 3 attempts counting.
- 9f11) In 'Mean of 3' rounds if the competitor has at least one DNF or DNS the mean is DNF.
- 9f12) In 'Best of x' rounds the order in the results is based on the best result per competitor, with lower meaning better.
- 9f13) In 'Mean of' and 'Average of' rounds the order in the results is based on the best average/mean per competitor, with lower meaning better.
- 9f14) If in 'Mean of' and 'Average of' rounds competitors have the same average/mean result, then the order in the results for these competitors is based on the best result per competitor, with lower meaning better.
- 9f15) Competitors with the same result in a round finish at the same position.
- 9f16) For the Rubik's Cube: Multiple Blindfolded event the order in the results is based on number of puzzles solved minus the number of puzzles not solved (higher is better). If the result is lower than 0, the solve is disqualified.
If competitors have the same result, then the order is based on total time (lower is better).
|9g)||A Combined round is two or three rounds combined during one time frame, where results of earlier rounds are taken into account for next rounds.|
- 9g1) A Combined round can be used to save time in the time schedule.
- 9g2) Whether a competitor proceeds to next phase of a Combined round, must be decided on position (best x competitors) or on result (all competitors with a best result under x).
|9h)||WCA must provide WCA world rankings for single and preferred average/mean formats where applicable.|
|9i)||Results of official WCA competitions must be listed on the WCA world rankings, if the full WCA regulations were applied.|
- 9i1) Regional records are recognised for best national/continental/world results.
- 9i3) If the regulations for an event are changed, then the old regional records stand until they are broken under the new regulations.
|9j)||Events must be held only once during a competition.|
|9k)||If an event is held, then all competitors may participate in that event.|
|9l)||All competitors must compete in each round during the same time frame.|
|9m)||Events must have at most four rounds.|
- 9m1) Events with 99 or fewer competitors must have at most three rounds.
- 9m2) Events with 15 or fewer competitors must have at most two rounds.
- 9m3) Events with 7 or fewer competitors must have at most one round.
|9o)||A Combined round and a Qualification round count as one round when counting the number of rounds per event.|
|9p)||For each round of an event, at least one competitor must not proceed to the next round.|
|9q)||Events and rounds should have at least 2 competitors.|
|9r)||A qualification round is a round of an event held before the first round of the event.|
The goal of a qualification round is to let unranked or low ranked competitors qualify for the first round of an event with many registered competitors.
- 9r1) When announcing the competition the organisation team must announce:
- how many competitors will compete in the first round of the event
- the maximum number of competitors in the qualification round of the event, and how many of the competitors will proceed to the first round
- which average/mean time or single solve time for the WCA ranking of the event is required to directly qualify for the first round (or other round) of the event
- the date taken for deciding the average/mean time or single solve time on the WCA ranking of each competitor
- 9r2) All competitors of an event who are not directly qualified for the first round of the event, must compete in the qualification round of the event.
- 9r3) There may be changes to increase the maximum number of competitors in qualification round or first round, or to add a qualification round for newly registered competitors. These changes should be made at least one month before the competition.
|9s)||If during a round a competitor does not solve within the time limit, then his solve may (courtesy of main judge) be stopped and disqualified by the judge. The main judge decides whether the competitor may continue the round, for example if the time was exceeded because of a puzzle defect.|
