__The commercial cube is composed of six fixed cubes, eight movable cubes on the corners and 12 movable cubes on the edges. Each cube is one of six colors. The Rubik's cube has red, yellow, blue, green, white, and orange colors. In its solved state, each color is on only one face. When the cube is rotated, the edges and corners move and the cube becomes scrambled. The challenge of the puzzle is to restore each cube to its original position. The cube is extremely challenging because there are slightly more than 43 quintillion (4.3 × 10 19 ) possible arrangements, and only one solution.__

Keeping white on top, turn the cube so that a different colour face is toward you. Follow the above instructions again. Repeat with the other two faces until the white cross is complete. This step is quite intuitive; you can do it for sure but it does take a little practice. Just move the white edges to their places not messing up the ones already fixed.

**Your goal is to have all four edges matching their centres. If you have this, then the cross is solved. If you have only two, then you could have one of two cases. Either the two matching edges are adjacent (next to each other) or opposite each other. If they are adjacent, hold the cube so that the two solved pieces are facing the front and left of the cube (shown in the left picture), then perform:**

**The standard Rubik's cube has sides of about 2.2 in (5.7 cm) per square. Various other sizes have also been produced such as a 1.5 in (3.8 cm) mini cube, a 0.8 in (2 cm) key chain micro cube, and a 3.5 in (9 cm) giant cube. While the standard cube is a 3 × 3 × 3 segmentation other types have also been introduced. Some of the more interesting ones include the 2 × 2 × 2 cube, the 4 × 4 × 4 cube (called Rubik's Revenge) and the 5 × 5 × 5 cube. The shape has also been varied and puzzles in the form of a tetrahedral, a pyramid, and an octahedral are among types that were produced. The Rubik's cube also led to the development of game derivatives like the Rubik's cube puzzle and the Rub it cube eraser.**

Assembling the Rubik’s Cube is a wonderful way to exercise your fine motor skills. And improve the spatial and visual perception and cognitive thinking in children. Once you have the cube put together, it will challenge the children to use their visual and spatial perception skills. The cube will also help children to learn about different colors and how to match them. Check it out here at amazon.com. Rubix Builders

__You can find assembly instructions for the BrickPi3 here. We will need to assemble the case, attach the BrickPi3, the Raspberry Pi, the Raspberry Pi Camera, add an SD Card, and add batteries. To make the software easier to setup, Raspbian for Robots comes with most of the software you will need already setup. You will need at least an 8 GB SD Card, and you will want to expand the disk to fit the full size of the SD Card.__

*Whether you complete all 6 stages or 1, be sure to tell your teacher about this program so all your classmates can solve with you! Teachers from all over the country use our program, at no cost, to teach their classes not only to solve, but math, art, science, and more. Hundreds of schools compete at solving cubes as a group and classes create really cool mosaic designs too. We even have ongoing mosaic contests each year. So check out our site and learn how you can do even more with a Rubik's® Cube!*

**The project uses the Pi to directly solve the Rubik’s cube. The BrickPi3 takes the unsolved Rubik’s cube and the Raspberry Pi takes a picture of each side of the Rubik’s cube with the Raspberry Pi Camera. The Pi creates a text map of the color squares that shows where they are located on the cube. When it has fully mapped the cube, the Pi uses the “kociemba” python library to map out the moves needed to solve the Rubik’s cube. This information is taken by the Pi and BrickPi3 to solve the Rubik’s cube using the LEGO motors. The result: a solved Rubik’s cube. Rubix Building Solutions**

The Rubik’s Build It, Solve It kit is for one player. Although ages 8 and up are recommended, I believe younger children will enjoy playing with the assembled toy. As we said before, it is great for children and adults that don’t mind trying to figure out how the cube works – it’s great for those that enjoy putting puzzles together. The kit gives an inside look on how the cube works and how it is put together. Plus, you will receive some tips in the instruction manual on how to solve it.

*Since the center pieces cannot be moved relatively to each other it's important to solve the edge pieces correctly in relation to each other. For example, when solving the white in our case- the green center piece is to the left of the red center piece, therefore the green-white edge piece should to be solved to the left of the red-white edge piece (see image).*

*There are various puzzles that involve colored square tiles and colored cubes. Some early precursors to the Rubik's cube include devices such as the Katzenjammer and the Mayblox puzzle. The Mayblox puzzle was created by British mathematician Percy MacMahon in the early 1920s. In the 1960s, Parker Bothers introduced another cube puzzle type toy called Instant Insanity. This toy achieved a moderate level of popularity in the United States. The early 1970s brought with it a device called the Pyraminx, which was invented by Uwe Meffert. This toy was a pyramid that had movable pieces that were to be lined up according to color.*

_{The arrangement of the cube is an excellent method to improve the cognitive, visual, spatial and motor abilities in kids. The process of arranging the cube will enable children to exploit their spatial and visual skills as they learn to adjust the tiles. It also enables children to identify colors and allow them to create perfect combinations. Check it out here. }

*Repeat the process. Turn back to your blue side and repeat the turns on opposite sides. Then, return once more to the red side and turn the opposite sides in opposite directions. And last, return once more to the blue side and turn the opposite sides in opposite directions. When you finish, you should have a staircase-like zig-zag across four sides of your Rubik’s cube.[4]*

^{The Rubik’s cube has recently begun making a comeback. Invented in 1974, it is the world’s best-selling toy. But solving them takes thought, effort, and skill . . . so why not let a robot do it? In this project, we take a Raspberry Pi, a BrickPi, and a set of LEGO Mindstorms and build a Rubik’s cube solving robot. Simply place an unsolved Rubik’s cube in the solver, run the python program, and your Rubik’s cube is solved! Build A Rubix Cube }

Begin with your cube solved. Once again, you want to start off with your Rubik’s cube in its solved position. Making a fish pattern on your Rubik’s cube is simple. The end result will have swapped two edge pieces so that the remaining ones look like a fish with fins. If you hold the cube diagonally it will look like a fish swimming away from you.[7] Rubiks Build It Solve It
