Rubik's Cube

  May 02, 2022    

The Rubik’s Cube was invented in 1974 by Ernõ Rubik, a Hungarian architecture professor. Rubik created the Cube as a learning exercise to teach his students about 3-dimensional spaces. 

By the 1980’s, the Rubik’s Cube was a worldwide craze selling millions of Cubes every year.On the original Rubik's Cube, each of the six faces was covered by nine stickers, each of one of six colours: white, red, blue, orange, green, and yellow. Some later versions of the cube have been updated to use coloured plastic panels instead (Stickerless), which prevents peeling and fading. 

Although the Rubik's Cube reached its height of mainstream popularity in the 1980s, its community is still growing with a official competition organizer (WCA)

WCA

  May 01, 2022    

Quoted from the worldcubeassociation.org, The World Cube Association governs competitions for mechanical puzzles that are operated by twisting groups of pieces, commonly known as 'twisty puzzles'. The most famous of these puzzles is the Rubik's Cube, invented by professor Rubik from Hungary. A selection of these puzzles are chosen as official events of the WCA.





The WCA organizes competitions for all "official" solves for twisty puzzles that are chosen by the WCA which also records the fastest solve in a specific twisty puzzles like World records (WR), National records (NR), and Continental record (CR). Every solve that is outside of WCA competitions is "unofficial" and if they solves faster than the WR than it's named Unofficial World Record (UWR). A WR is of course more valuable than a UWR.
