SPEEDCUBER anglicism derived from the English SPEED, velocity and CUBE, cube, from which in turn derives CUBER, which makes the cube; term that designates competitors who try to solve the Rubik's Cube in the shortest possible time. The cube is easy to solve in its first two stages, not so the third, in which the faces are disarmed already of a single color. A task that 98% of the world's population cannot solve, speedcubers achieve it in a few seconds, even blindfolded or with their feet, in 2x2x2, 3x3x3, 4x4x4 and other formats such as pyramidal, spherical and other variants.
