The piece in the center of each side is the center piece Look directly at the specified side indicated to determine which direction is clockwise or counterclockwise.įor the central horizontal slice H, look at the cube through the top side to determine the clockwise direction. A letter with an apostrophe (') means to turn the side counterclockwise one quarter turn (a -1 can be used in place of an apostrophe, but the apostrophe takes up less space).įor example, U F2f2 D' Ll means to rotate the upper side clockwise one quarter turn, the front side and 2nd layer in from the front side clockwise twice (half way around), the down (bottom) side counterclockwise one quarter turn, and the left side and second layer in from the left side clockwise one quarter turn. A letter with a 2 following it means to turn the side two turns (halfway around). Since the lower case L: l looks like the number 1, a letter by itself means to turn the side clockwise one quarter turn.
