Rubik scrambled his own invention and needed a month
Ernő Rubik, a Hungarian architecture professor and sculptor, invented the 3×3×3 combination puzzle in 1974 as a Magic Cube—first to solve a structural puzzle of rotating layers that would not fall apart. Only after scrambling it did he see the toy; restoring order took him about a month. Roughly 500 million cubes had sold by January 2024.
Each of six faces once carried nine stickers in white, red, blue, orange, green, and yellow; later editions use plastic panels. Since 1988 the colour opposites are standardised—white opposite yellow, blue opposite green, orange opposite red—with red, white, and blue clockwise. An internal pivot lets each layer turn independently until every face is a single colour again. Larry D. Nichols filed a magnetic 2×2×2 patent in 1970 (U.S. grant 1972), and Frank Fox patented a spherical sliding amusement in 1974, but Rubik’s interlocking plastic core proved more durable for mass play.
Hungary granted patent HU170062 after a 30 January 1975 filing. Budapest shops saw test cubes in late 1977. Tibor Laczi showed one at Nuremberg’s toy fair in February 1979; Tom Kremer of Seven Towns brokered an Ideal Toys deal that September. Ideal rejected names like “Gordian Knot” and “Inca Gold,” chose “Rubik’s Cube,” and exported the first branded batch from Hungary in May 1980 after Western safety tweaks. Awards piled up that year, including Germany’s Game of the Year special prize for Best Puzzle; U.S. National Toy Hall of Fame induction came in 2014.
From 1980 to 1983 about 200 million cubes sold. March 1981 brought a Guinness speed event in Munich and a Scientific American cover; June 1982 hosted the first world championship in Budapest. Solving books flooded shelves—James G. Nourse’s The Simple Solution sold over six million copies in 1981 alone. Sales crashed by late 1982 in the West even as China and the USSR still queued. A 2003 Toronto championship with 83 competitors revived sport cubing and led to the World Cube Association in 2004; patents expired in 2000, freeing Chinese speed cubes. Spin Master agreed in October 2020 to buy the brand for $50 million.
Speedcubers still chase records under WCA rules worldwide, decades after the 1980s fad.
