Rubik's Cube
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)
