The Rubik’s Cube has come a long way since its invention in Communist Hungary. The puzzle that would capture the world’s imagination was invented by Erno Rubik, an enigmatic professor of architecture, in 1974. Rubik is famously publicity-shy, and has a Sphinx-like love of riddles and elliptical comments when he does speak.

Rubik’s Cube was a smash. By 1982, just two years after its international debut, 100 million had been sold. A market for how-to guides emerged, and Cube-­related books soared to the top of best-seller lists. A National Geographic spread in the early 1980s showed two Amazonian Indians in loincloths fiddling with a Cube. Ronald Reagan, apparently unaware the puzzle was invented in a Communist country, hailed the Cube’s success as an example of American entrepreneurial genius.
