# Rubik's Cubes

In 2020, the puzzle invented by Hungary's Ernő Rubik celebrates the 40th anniversary of its international launch. The original 3 x 3 x 3 format has now expanded to embrace the dodecahedron-shaped Megaminx, the Pyraminx, the Clock (a two-sided puzzle, each face featuring nine clocks to be aligned) and more. Grégoire Pfennig (France) has even made a 33 x 33 x 33 version – the largest-order Magic Cube, with 6,153 parts. But if you’re new to Rubik's Cubes, start simple! You’ll find lots of online videos on how to solve the iconic 3 x 3 x 3 puzzle. When you’ve mastered it, you could upload some footage of yourself in action, which might inspire others in turn.

## Rubik's Cube record

In a mean time of just 9.42 seconds, Max Park (USA) solved a 3 x 3 x 3 Rubik's Cube using only one hand at the Berkeley Summer 2018 event in California, USA, on 15-16 September. His individual times were 9.43 seconds, 11.32 seconds, 8.80 seconds, 8.69 seconds and 10.02 seconds, with the lowest and highest times not counted towards the average as per the World Cube Association rules

The World Cube Association (WCA) has regulations for speed-solving, which GWR follows. We've provided an overview of the WCA’s guidelines for attempting puzzles blindfolded here, but go to worldcubeassociation.org for the full details

• You're expected to supply your own blindfold for the attempt.
• Each speed-solving record category will have a time limit, which the organizers will announce before the start of each attempt.
• If you're likely to solve the puzzle in under 10 minutes, a StackMat will be used. This is the standard timer employed at WCA events. If the solve is likely to take longer, however, the judge will use a stopwatch.
• Prior to the attempt, you’ll submit your puzzle to a scrambler, who'll rearrange each face of it. The cube is then covered.
• When you're ready to start, the judge will ask "OK?" Once you respond, the puzzle will be uncovered. If you’re using a StackMat, the timer is triggered when you lift your hands.
• You’ll have time to memorize the appearance of the cube before you pull the blindfold over your eyes and start the solve. But you can't manipulate the puzzle until your eyes are covered.
• When you think you've finished, release your cube to stop the timer.
