Rules


The championship rules are provided by the World Cube Association (WCA, to be fully established before end of 2004).

Below you can find the basic rules.

Full regulations can be found here.

Basic rules

All events:
The championship is organised by the WCA (World Cube Association), a non-profit organisation to promote and standardise Rubik's puzzle competitions.
The championship is open to all citizens of the European countries and Israel.
A passport/id-card must be shown during registration in Amsterdam to prove your identity.

A master caller announces competitors with their name or group number or registration number.
After the announcement competitors stand in a line until it is their turn to compete.
Competitors have 3 minutes to show up to compete.

A judge thoroughly scrambles the puzzle using computer generated algorithms.
Per round all competitors need to solve the same scrambled positions.

Competitors can use their own puzzles. Only official Rubik (!) brand puzzles are allowed. If you don't have Rubik brand puzzles, then you can borrow a slightly prepared puzzle from the organisation team. Some well-known companies producing Rubik's brand puzzles are: Hasbro, Ideal Toys, Oddzon, Kroeger Inc, Winning Moves, Studio Giocchi, Jumbo, Rubik Studio, Hessport/Rubiks.com, PALBOX, Amo Oy.
Puzzles may be made smoother internally by sanding or using any lubricant. No modifications are allowed that enhance the basic concept of the puzzle.
Competitors can use any normal 6 colour sticker scheme for cubes, as long as the cubes show 1 colour per face in solved position.

Speed solving events:
The StackMat timers are used for time measurement.
Competitors have 15 seconds preinspection. After the preinspection the puzzle is covered by a judge. The competitor places the hands flat on the stacktimer.
When the competitor is ready, the judge uncovers the puzzle. The competitor has 3 seconds to pick up the puzzle.
Time starts when the competitor's hands leave the stacktimer. Time stops when the competitor's hands touch the stacktimer again.

Blindfold events:
Stopwatches are used for time measurement. (3x3x3 final will be on stage using StackMat timers and stopwatches as a back-up.)
Puzzles are covered until the competitor is ready to compete.
Time starts when the puzzle is uncovered.
After memorising the puzzle, the competitor covers his/her eyes with a blindfold provided by the judge.
As soon as the eyes are covered with the blindfold, the competitor can start solving the puzzle.
The competitor tells the judge to stop the stopwatch, when the competitor thinks the puzzle is solved.
