Overview Of Rubik's Cube

Game Rules

Getting to Know Your Rubik’s Cube:

1.Identify the pieces. Before you start playing Rubik’s Cube, identify the different pieces of it. This will help you understand the mechanics of the Cube and more quickly solve it.

There are several different sized Rubik’s Cube games. For example, the original Rubik’s Cube is called “3x3.” This means that there are three layers to the Rubik’s Cube- a top, a middle, and a final layer.

The other sizes are 2x2, 4x4, and 5x5.

2.Identify the center pieces. On each side of your Cube are center pieces, which have only one color on them. The colors are either red, blue, white, yellow, green, or orange.

There are six center pieces located in the center of each side. Center pieces do not move and represent the color of a specific side.

Center piece colors always have a specific color opposite them on the Cube.White is always opposite yellow, orange is always opposite red, and green is always opposite blue.

3.Identify the logo piece. On your Cube, the logo piece is one color, usually white, and has the Rubik’s Cube logo on it.Generally, you’ll start with this side of the Cube facing up.

There is only one logo piece

4.Identify the edge pieces. On your Cube, each edge pieces have two different colors.These are often the last pieces of each layer that you will solve.

There are a total of twelve edge pieces on a Rubik’s Cube.

5.Identify the corner pieces. On your Cube, the corner pieces have three different colors.

There are a total of eight corner pieces.

Solving the Top Layer:

1.Position your Rubik’s Cube with the white center logo piece facing up. As you prepare to solve your Rubik’s Cube, it’s important to have this piece with the logo facing upwards. This will make it easier to solve each layer of the puzzle.

If your Rubik’s Cube is in a “solved” state at this point, you’ll first need to shuffle the pieces so that you can play.

2.Make a white cross across the top. With the center white logo piece facing up, position the pieces into the shape of a white cross.

This is one of the more difficult stages, so practicing it through trial and error will help you improve at solving the Cube.

It’s important to solve each section of your white cross in this specific order: blue, orange, green, red.

Make sure that the edge piece colors correspond to both the top white center logo piece and the red and blue side and center pieces.If the pieces are in these positions, you know you’re on the right track.

If you’ve made any mistakes, try reconfiguring the pieces until you get them into the correct alignment.

3.Solve the white corners. After you’ve created your white cross on the top face of the Rubik’s Cube and positioned the edge pieces properly, you’re ready to solve the white corners. By making sure that you’ve solved the white cross on the top layer before you position the corners, you’ll have an easier time positioning the proper pieces in the middle layer.

The white cross should still be on the top face of the Cube.

Remember that each corner pieces will have one white side and sides with two other colors.

If a corner piece is located on the bottom side or layer, then rotate it until the corner is directly below where you want it. From here, move the pieces until you get the corners into the correct position.

Follow the same steps to position the pieces until the corners align and the entire top side of your Cube is white.

Solving the Middle Layer:

1.Position Rubik’s Cube with white cross on the bottom. In order to properly solve the middle layer, position the completed white side on the bottom.This will set you up to put the edge pieces in their proper positions.

2.Position edge pieces. By putting the edge pieces into position on the middle layer first, you’ll more easily be able to position the rest of the layer.

It’s very important to note the vertical row of either blue, red, orange, or green.

Position the pieces until they’re in a vertical line by rotating the top side until the front color of the edge piece on the top side (without yellow) matches one of the side center pieces.How you move the edge piece is determined by the top face of that edge piece.

3.Follow the above steps until the edge pieces are in the correct position. At this point, the middle layer should be finished so that you can move on to solving the final layer.

If you have made any mistakes, manipulate the pieces until they’re in the proper positions.

Solving the Final Layer

1.Position Rubik’s cube with yellow-patterned side facing up. At this stage, you’ll have a yellow pattern on one face of your Cube. In order to properly solve the final layer, position the side with yellow pattern upwards.This will set you up to put the edge pieces in their proper positions.

At this point, the yellow pieces on the top don’t have to match the side pieces.

2.Make a yellow cross. Just like you did with the white face, position the yellow pieces into a cross.This will help you more easily position the remaining pieces on the final layer.

3.Make the corners yellow. You’re now ready to position the final pieces of your Rubik’s cube by making the remaining corners on this layer yellow.

Once you’ve positioned the yellow corners, you should have a completed Rubik’s Cube!

Origin Of Rubik's Cube

The Rubik's cube was invented in 1974 by the Hungarian professor of architecture Ernö Rubik. Some people may remember of it as the Magic Cube since at the beginning its inventor named it "Büvös Kocka", the Hungarian name for Magic Cube. 

The Hungarian cube was firstly a success in its native country, and then it became a real triumph in the whole world. The object had been conceived at first in order to develop the faculties of visualization of the pupils in architecture. It turned out afterward that the educational dimension of the Rubik's Cube was much important... It is indeed a natural and material representation of some mathematical principles.

First Idea:

In fact Ernö Rubik had the first idea in spring 1974. He does several attempts and solve the cube for the first time summer (it took him one month to solve it). The final technical solution is ready at the end of the autumn of the same year.

At the beginning of year 1975, Ernö Rubik starts up the necessary process to apply for a patent and starts searching a partner for the industrial production, which finally begins in 1977. The cube quickly becomes very popular in Hungary.

Popularity:

The international interest in the cube began in 1980 to last until about 1983. During this period, a great number of Rubik's Cube was sold.

There were many broadcasts with speed competitions and shows around the cube. There was even a cartoon which dedicated to it. Many clubs were also created almost anywhere.

Etymology:

Rubik's Cube was first called the Magic Cube (Buvös kocka) in Hungary. The puzzle had not been patented internationally within a year of the original patent. Patent law then prevented the possibility of an international patent. Ideal wanted at least a recognizable name to trademark; of course, that arrangement put Rubik in the spotlight because the Magic Cube was renamed after its inventor in 1980.

First Debut:

The first test batches of the Magic Cube were produced in late 1977 and released in Budapest toy shops. Magic Cube was held together with interlocking plastic pieces that prevented the puzzle being easily pulled apart, unlike the magnets in Nichols's design. In September 1979, a deal was signed with Ideal to release the Magic Cube worldwide, and the puzzle made its international debut at the toy fairs of London, Paris, Nuremberg and New York in January and February 1980.

First Rubik's Cube Manufacture:

The progress of the Cube towards the toy shop shelves of the West was briefly halted so that it could be manufactured to Western safety and packaging specifications. A lighter Cube was produced, and Ideal decided to rename it. "The Gordian Knot" and "Inca Gold" were considered, but the company finally decided on "Rubik's Cube", and the first batch was exported from Hungary in May 1980.

First World Championship:

At this time the first world championship took place on June 5, 1982 in Budapest. 19 cubists of different nationalities took part to the event.

The cubes were scrambled by computer, then brought on the spot in sealed cases. The cube was placed on a pad with a photo sensitive diode at the bottom. The competitors had the possibility to examine the cube during 15 seconds before starting to solve.

The first places were hold by:

1. Minh Thai (USA) 22.95 s

2. Razoux Schultz (Netherland) 24.32 s

3. Zoltán Lábas (Hungary) 24.49 s

Governing Bodies

World Cube Association:

The World Cube Association (WCA) is an organization that regulates and holds Rubik's Cube competitions. It was founded by Ron van Bruchem of the Netherlands and Tyson Mao of the United States. The goal of the World Cube Association is to have "more competitions in more countries with more people and more fun, under fair conditions".

History of WCA:

In 1999, the first modern age speedcubers found each other on the Internet via Rubik's Games, a computer game with an electronic version of the Rubik's Cube. Chris Hardwick from Raleigh, NC founded the Yahoo! Group "Speedsolvingrubikscube" and the Unofficial World Records, a place where cubers could post their personal best times. Ron van Bruchem started speedcubing.com together with his friend Ton Dennenbroek, an avid puzzle collector.

Because the cubers were living all over the world, they wanted to organize a competition at which they could all meet. In 2003, under the guidance of Dan Gosbee, they organized the Rubik's Cube World Championship in Toronto. This first modern-age Rubik's Cube competition was a huge success, but there were lots of issues, due to the lack of good regulations. After the World Championship, Ron van Bruchem and Tyson Mao started organizing competitions in the Netherlands and Germany, as well as at Caltech in the United States. In 2004, they started the World Cube Association, which today has held competitions in 70 different countries.
