blindfolded before beginning to turn the cube's faces. Their recorded time for this event includes both the time spent
examining the cube and the time spent manipulating it.
- In multiple blindfolded, all of the cubes are memorized, and then all of the cubes are solved once blindfolded; thus, the main
challenge is memorizing many - often ten or more - separate cube positions. The event is scored not by time but by the number
of solved cubes minus the number of unsolved cubes after one hour has elapsed.
- In fewest moves solving, the contestant is given one hour to find his or her solution, and must write it down as an algorithm.
World records
- Invented in 1974 by Hungarian sculptor and professor of architecture Erno Rubik
- Originally called the Magic Cube
- In the mid-1970s, Erno Rubik worked at the Department of Interior Design at the Academy of Applied Arts and Crafts in Budapest. Although it is widely reported that the Cube was built as a teaching tool to help his students understand 3D objects, his actual purpose was solving the structural problem of moving the parts independently without the entire mechanism falling apart. He did not realize that he had created a puzzle until the first time he scrambled his new Cube and then tried to restore it
