|2r)||Failure by the competitor to accept the final ruling will be grounds for disqualification of the competitor.|
|3a)||Competitors must bring and use their own puzzles. Competitors may borrow puzzles from other competitors, as long as both competitors are ready to compete when they are called for to do so.|
|3b)||Puzzles must be in reasonable working order, so that normal scrambling is possible.|
|3c)||Competitors can use any normal 6 colour scheme for cubes, as long as the cubes show 1 colour per face in solved state. For other puzzles competitors can use any generally available variation that has the same moves, positions and solutions as the original puzzle.|

|3k)||Puzzles must be approved by a judge before the competitor can compete.|
|4a)||A scrambler must apply the scrambles.|
|4b)||Puzzles are to be scrambled using a computer-generated random scrambling algorithm.|
|4c)||Standard metrics for scrambling and solving is Half Turn Metrics, where each move of 1 side counts as 1 move, and inner slice moves as 2 moves.|
|4d)||Cubes are generally scrambled with the white (or the lightest colour) face on top and green (or blue or the darkest face) on the front.|
|4e)||If a competitor wants other colours, then he must name the colours during registration.|
|4f)||Competitors have to solve the same scrambles per round.|
|4g)||At the main judge's discretion, scrambling algorithms in a given solve of preliminary rounds may be randomly chosen from a pool of scrambles, for example to prevent cheating in larger competitions.|
|4h)||The number of moves varies for each puzzle:|
|5a)||Puzzle defects are unintentional defects of puzzles (like: pieces popping, wires breaking, screws/caps/stickers falling off) that make it impossible or harder to solve the puzzle.|
|5b)||If a puzzle defect occurs, the competitor may choose to repair the puzzle and continue the solve or choose to stop the solve.|
|5b1)||If a competitor chooses to repair the puzzle, then he may only repair the defective pieces, not using pieces of other puzzles.|
|5b2)||During the repairing of the puzzle, the competitor may not intentionally make the position easier to solve than before the defect.|
|5b3)||If after repairing the puzzle, but still during the solve, the competitor notices that the puzzle is unsolvable, he may disassemble and assemble max. 3 pieces to make it solvable again.|
|5b4)||For blindfolded events a puzzle defect may only be repaired during the solving, and must be done blindfolded. A competitor may use internal markings only for piece orientations, to help himself assembling the puzzle into a solvable state. Any other markings are not allowed.|
|5b5)||If after the solve a non functional part of the puzzle is still defect (like a center cap of a cube) or not fully rotated (like a 5x5x5 center piece twisted in its spot), but the puzzle is otherwise unambiguously solved, the puzzle is considered solved, under discretion of the main judge.|
|5c)||In 'Best of' and 'Average of 5' rounds solves with a puzzle defect cannot be exchanged by an extra attempt.|
|5d)||In 'Mean of 3' rounds solves with a puzzle defect may be exchanged by an extra attempt.|
|5d1)||There may be maximum 1 extra attempt per round.|
|5d2)||In order for the competitor to declare a puzzle defect, he must declare the puzzle defect ten seconds after the puzzle defect occurs or three seconds after the repairing of the puzzle, but always before the timer is stopped.|
|5d3)||A judge may decide to disqualify a solve or to not award an extra attempt, if the competitor's puzzle defect is ruled intentional, under discretion of the judge.|
|7a)||Competitions can be held on any location, inside or outside, on special stages or normal floors.|
|7b)||Audience must be at least 1.50 meter away from the competitors.|
|7c)||Lighting of the competition area needs special attention, with preferably white light, so that competitors can easily distinguish the colours of puzzles.|
|7d)||The temperature of the competition area should preferably be 21 to 25 degrees Celsius.|
|7e)||The competition area must be smoke-free, and must preferably have a reasonable noise level.|
|7f)||The timer is placed directly (no objects underneath it) on a table, desk or console that suits solving while standing. For Solving With Feet the timer is placed directly on the floor.|

|8d)||Competitions may have time limits per round of an event, to make sure that the time schedule can be followed.|
|8e)||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 can continue the round, f.i. if the time was exceeded because of a puzzle defect.|
Events must have one of the following formats:|
- 'Best of'
Competitors get a limited number of attempts, with the best attempt counting. Example 'Best of 3'. There may be a combined time limit, example: 30 minutes for 'Best of 1' or 'Best of 2'.

|9i)||All competitors must compete in each round during the same time frame.|
|10a)||Before the competition all competitors must make themselves aware of the solved state per event.|
|10b)||Only the resting state of a puzzle is considered, when the timer has stopped.|
|10c)||Puzzles may be in any orientation at the end of the solve.|
|10d)||All pieces of a puzzle must be fully attached to the puzzle, and in their required positions. See also article 5 Puzzle defects.|
|10e)||Cubes (and similar puzzles) are solved when all sides are restored to solid colour states.|
If one or more parallel slices need to be turned to reach the solved state then:
In all other cases the solve is disqualified.
- 10e1) If all slices comply to regulation 10f, then the cube is considered solved, without a penalty.
- 10e2) If one or more adjacent slices do not comply to regulation 10f, then the cube is considered solved, with a penalty of 2 seconds.
|10f)||A slice of a cube (and similar puzzles) may be misaligned in the following manner. The inner corner of the misaligned slice (or group) may not cross the inner edge of the connecting slices. For 2x2x2 Cube the slice may not be more than 1/8 turn away from solved state.|
Examples no penalty:
|10g)||For Rubik's Magic (and similar puzzles) the puzzle must be flat on the surface. The maximum elevation of any part of the puzzle at the end of a solve is two tiles higher than flat.|
|10h)||Other puzzles are solved according to the solved state as defined in the generally accepted goal of the puzzle, with the regulations of the cube solved state applied when applicable.|
