![]() Thus, t1 means to turn the top layer one unit (30°) clockwise looking at the layer t-1 means to turn it 30° counterclockwise. In order to instruct how far to turn the top or bottom, the letters t and b will be followed by a number indicating the number of "units" to turn the layer (1 unit = 30 degrees). R means to rotate the right half of the cube along the vertical axis one half-turn (180°).With this in mind, the following notation will be used: Because each of the corners is essentially twice as wide as each of the edge pieces, the basic unit of rotation for the top and bottom is the width of an edge, or 30°. The primary moves available for the Square 1 are to turn the top, turn the bottom, and rotate along the central vertical axis (there is only one vertical axis since the middle layer only contains two pieces, as shown in the adjacent figure). This is exactly opposite the way the "mirror" representation works. In that case the bottom view represents what you would see if you looked directly at the bottom. All that matters is that you line up the middle layer such that the right half of the cube can be rotated when needed.īe aware that in Step 1, when describing how to return the Square 1 to a true cube from any shape, the figures do not use the "mirror" representation rather, end on views are used. Consequently, I will always show the middle layer as being square, even though it could be non-square at any time simply ignore its configuration. The orientation of the two pieces in the middle layer does not matter until the final step. The diagrams show all six sides of the cube by pretending that mirrors are being held up so that you may see the "hidden" sides. I will only show a 3D representation of the Square 1 when the top and bottom layers are truly square, as shown in the adjacent figure. My directions for Solving the Pyramix (Pyramid) See Denny's solution for solving the 4x4x4 cube (mirrored from the now missing ) This is a more detailed solution for the 3x3 than the one I provide (mirrored from the now missing ) See Denny's solution for solving the 3x3x3 cube. My directions for Solving the Rubik's Cube (3x3x3) - these also apply to the 2x2x2 Purchasing Puzzles: If you are having troubles finding stores that sell cubes and similar puzzles, I have a list of on-line sites that may have what you're looking for. I would appreciate any and all feedback or questions about the instructions please see the end of this page for the e-mail address. ![]() These directions are a graphical version of those given by Andrew Arensburger and Christian Eggermont ( Another useful Square 1 solution can be found at Jaap's Puzzle Page. (Ri, L) (Bi, F) (Ui, D) (Ri, L) The first and last algorithms are the same, and you must repeat them as shown.These instructions can be used to help you solve the Square 1, a fiendishly difficult puzzle introduced in 1992. For example, in the first algorithm, (Ri, L), You turn the right side counter-clockwise, and you turn the opposing side clockwise. Algorithms in this project are grouped together using parenthesis (), much like coordinates on a graph. As you will see, the algorithms use one inverted movement, and one standard movement of the opposing side. To solve this, you will use four algorithms, each made up of two corresponding movements. ![]() (You can impress your friends by saying that you used and algorithm to solve this.) An Algorithm is just a set of rules used in problem solving. Example: Ri = Right side, inverted (counter-clockwise) D = Down (clockwise) These notations make up Algorithms which sounds fancy and smart, but is actually quite simple. This is very important, because if you reverse the direction for which you turn the side, it can mess you up. This goes after a side abbreviation, and it means that you turn the specified side counter-clockwise, as if it were facing you. F = Front (the side that faces you) B = Back(the side that faces away from you) BT = Bottom(The side that faces down) R = The right side L = the left side * = Inverted. Before you start, you will have understand some basic notation, or these steps will confuse you.
