The 3x3 twist puzzle has been a pop culture icon since Ernő Rubik released his famous cube in the 1970s. The basics of play haven’t changed in the intervening decades, but as competitive cubing (commonly referred to as speed cubing) has become more popular, the cubes themselves have evolved to support faster solving. Layers have gotten easier to twist, magnets and springs have been added to keep the whirlwind under control, and inner cores have been redesigned to let you start moving one side before the previous one slips into place.
