Rubik's Cube - 50th Anniversary

On March 10, 2025 the Ministry of Digital Development of the Kyrgyz Republic puts into circulation a 2024 Kyrgyz Express Post postage stamp: "Rubik's Cube, 50th Anniversary".

The Rubik’s Cube (Magic Cube) is a mechanical puzzle invented in 1974 by Hungarian sculptor and architecture professor Ernő Rubik. It was patented in Hungary in 1975 and gained extraordinary worldwide popularity during the 1980s.

The player's task is to "solve the Rubik's Cube" by rotating its faces to restore it to its original state, where each face consists of squares of the same color. Enthusiasts of speed-solving the Rubik’s Cube are called speedcubers, and the activity itself is known as speedcubing. In the classic 3x3x3 Rubik's Cube speedcubing discipline, the current world record for a single attempt is 3.13 seconds, set by American Max Park. Speedcubing competitions are held at the European, Asian and world levels.

In May 2024, a robot developed by Mitsubishi Electric engineers set a new Guinness World Record by solving the Rubik’s Cube in 0.305 seconds, surpassing the previous record.

In addition to mechanical versions, electronic versions of the Rubik’s Cube also exist.
