The standard Rubik's cube, 3x3x3. Invented in 1975, and much improved since then! Stickerless, magnets, variable tensions, mini, and everything in between. The world record time for solving a 333 Rubik's Cube is 3.47 seconds, held by Du Yusheng. The world record average of the middle three of five solve times (which excludes the fastest and slowest) is 5.53 seconds, set by Feliks Zemdegs.
