Hello and welcome to our coverage of the
Rubik’s Cube World Championships in Seoul, South Korea.

It’s the final day of the competition, in
which hundreds of “speedcubers” are competing across 17 events. These
range from competing to solve the classic cube in the shortest time, to
tackling it blindfolded or one-handed, to cracking other so-called “twisty
puzzles” such as the pyramid-shaped Pyraminx or the dodecahedron-shaped
Megaminx.

Designed in 1974 by the Hungarian
architect Erno Rubik as a teaching tool, the Rubik’s cube is now one of the
best-selling toys of all time. Speedcubing has surged in popularity, with the
world record for solving the puzzle now 3.13 seconds – a fraction of the first
world record of 22.95 seconds, set in 1982.
