Now today, I’m only going to explain how to solve one face of the cube due to the limited amount of time. But the one that I have found to be easiest to understand was the Fridrich Method. As I said before, there are many different algorithms and ways to solve a Rubik’s cube. In the next few minutes, I would like to share with you how to solve the Rubik’s Cube. There are a variety of methods used to solve a Rubik’s Cube, but the most popular and the most effective is called the Fridrich method. Solving a Rubik’s Cube requires some study and decision-making. Little did Rubik know that his cube would become a sensation around the world with the first world championship held in his native, Budapest, in 1982, with a sixteen year old Vietnamese girl winning the competition, unscrambling the Cube in 22.95 seconds. However, Rubik did not give the cube his name-he called it the “Magic Cube.” It was renamed the Rubik’s Cube by the Ideal Toy Corporation in 1980. He was working on a model that would help him explain a three-dimensional geometric when he finally ended up creating the famous, colorful cubical form we know as a Rubik’s cube! The top face has a circle with a long red line and a short green line.In 1974, a twenty-nine year old Hungarian named Erno Rubik was trying to solve a structural design problem. If this notation is still confusing, click on Figure 1 to see example figures demonstrating the move.įor sides with whole pictures rather than just logos, the above two figures Orient the cube as shown in Figure 1, placing the side with the piece that needs to be rotated on the left, then perform Move 1 to rotate the piece 90 degrees clockwise. After completing Move 1, it will need to be rotated 180 degrees, and Move 2 can be used to accomplish this. If no pieces need to be rotated 90 degrees counterclockwise, then there must be one that needs to be rotated 90 degrees clockwise, so place it on top. Otherwise, position the cube so that a piece that needs to be rotated 90 degrees counterclockwise is on the top. If your cube has logos on four faces and solid colors on two of the faces, orient the cube so the solid color is on top and the logo to be rotated is on the left. Since it is impossible to rotate just one piece 90 degrees on a cube, this move has the side effect of rotating the top middle-center piece 90 degrees counterclockwise. Pretend that the sides are like doors mounted on hinges, and have swung open so that you can see them. Instead, the hidden sides are displayed as "hinged" to their neighbors. Also, since we're dealing with pictures/logos now, we will no longer use the "mirror" convention to show reflections of the hidden sides. Move 1 rotates the piece clockwise, while the Reverse of Move 1 rotates it counterclockwise. Use the following move (or its reverse) to rotate each of the middle-center pieces that needs to be rotated by 90 degrees. Move 1: Rotating a middle-center piece by 90 degrees To further clarify this notation, Move 1 has detailed accompanying figures to better describe it. Look directly at the side described to determine which direction is clockwise.ĭetermine the direction to rotate the V (vertical) slice by looking through the right hand face.ĭetermine the direction to rotate the H (horizontal) slice by looking through the top face. Remember, each side descriptor refers to the side with respect to the figure the move is referenced to.Īs before, numbers describe how to rotate a side, clockwise if 1, counterclockwise if -1, and 180 degrees if 2. H refers to the horizontal slice sandwiched between the top and bottom sides.V refers to the vertical slice sandwiched between the left and right sides.The new moves are used to describe rotations of the middle slices, both the horizontal slice between the top and bottom sides, and the vertical slice between the left and right sides. In order to describe these moves, we need to define two new moves in addition to the old ones. Once the cube is solved, the following moves can be used to rotate the middle-center pieces of specific sides. Still, use the centers as reference, but don't worry about their orientation until the cube is completely solved. If you have pictures, it's a bit harder since the centers are part of each picture and you'll need to look at them to help you determine how to position the corner pieces in step 1 and step 2. If you just have logos, this is simple since they're easy to ignore. The first step is to solve the cube using the directions given on the solution page, while simply ignoring the orientation of the centers. If your cube has a picture on each face or a logo in the center of each face, some extra moves are required to take care of this. How to handle pictures or logos on the faces
