The most important part in the manufacture of a Rubik's cube is designing the mold for the various pieces. A mold is a cavity carved into steel that has the inverse shape of the part that it will produce. When liquid plastic is put into the mold, it takes on the mold's shape when it cools. The creation of the mold is extremely precise. The cavity is highly polished to remove any flaws on the surface. Any flaw would be reproduced on each of the millions of pieces that the mold will produce. In the manufacture of the cube parts, a two piece mold is typically employed. During production, the two mold pieces are brought together to form the plastic part and then opened to release it. The tool includes ejector pins that release the molded parts from the tools as it opens. All the parts are molded with auto gating tools that automatically remove the parts from the sprue as it is ejected. The molds are also produced with a slight taper, called release angle, which aids in removal. Finally, when molds are designed, they are slightly bigger than the pieces that they ultimately will produce. This is because as the plastics cool, they shrink. Different plastics will have a different shrink rate, and each tool must be specifically designed for the material that will be used.

There are 5 different positions your cube can be in now, one of which could be solved. The rest of them have all four corners solved, so do the required amount of U moves so that every corner is in its right place. 2 of the 4 remaining possibilities have a solved bar (as mentioned above, where all three colours on that side are the same), and the other 2 have no solved bars.


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.

When it comes to building the Rubik’s Cube, it’s not as hard as it looks. In all actuality, it will take about fifteen minutes and the instructions are easy to follow. When it comes to placing the colored tiles, make sure you pay attention to where you’re supposed to place them, because if you snap them in the wrong place, you won’t be able to remove them. Yes, you will still be able to use the Rubik’s Cube, but you won’t be able to follow along with the instruction guide on solving the puzzle. Rubix Builders
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!

Even in the manual it states that you will need to practice using trial and error. Personally, we have a feeling that people who like doing puzzles and working things out will enjoy this more. It is important that you have patience when it comes to building the Rubik’s Build It Solve It cube. However, once you get the hang of this you are going to feel pretty smart. And your friends will be really impressed  because it takes a bit of effort to solve one of these cubes. If you would like to read our review on the d-fantix cyclone 3×3 – please click on the link.

Here, we're looking at the colours that aren't solved. There are 21 different cases for the top layer, but we only need a couple of algorithms to solve them all. The first thing we want to find is headlights. Only 2 of the cases don't have any headlights (one of them is if you skip this step, and the cube is already solved). For the one case without headlights, just perform the algorithm below from any angle. This is a better case because when you do the next step, the cube will be solved already.

Just because this kit gives you a behind-the-scenes look as to how a Rubik's Cube is made along with tips for how to solve it doesn't mean that you'll be solving it like a pro within seconds. Even the solution booklet itself says that the first step will take practice and trial by error. So this is definitely going to be more fun for kids or adults who enjoy the puzzlement of a Rubik's Cube and have the patience to build it and practice using the solving tips. But once you finally do solve it, you'll be pretty proud of yourself, and your friends and family will be impressed.
If there are no more edges left on the top layer, then they are probably either inserted in the right place but flipped, or inserted in the wrong place. To get an edge out of somewhere it shouldn't be, just insert one of the yellow edges into that slot. This should get the edge out and on the top layer, ready for you to use the above instructions to insert correctly.

Finally, we add a camera arm.  In the original design by MindCubr, this held the EV3 color sensor over the Rubik’s cube.  In our modified design, it holds a Raspberry Pi Camera over the Rubik’s cube.  We use two LEGO Mindstorms motors to manipulate the cube: the first sits below the cradle to rotate the cube, and the second moves the shuffler arm to spin the cube on an opposite axis.

The robot will turn the cube to each face and the camera will take 6 pictures, one of each side of the Cube.  The Raspberry Pi will determine the cube configuration from the six pictures. The Cube configuration will be passed to the kociemba Python library to find an efficient solution. Finally, the robot will execute the moves to solve the Rubik’s Cube!


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]
There are many approaches on how to solve the Rubik's Cube. All these methods have different levels of difficulties, for speedcubers or beginners, even for solving the cube blindfolded. People usually get stuck solving the cube after completing the first face, after that they need some help. In the following article I'm going to show you the easiest way to solve the cube using the beginner's method.

Constructing the Cube is a superb way to exercise those fine motor skills, visual and spatial comprehension and cognitive thinking from children. When the block is placed together, it is going to challenge the small ones to use their spatial and visual understanding as they know to spin the tiles. The block also helps kids learn about colours and fitting them. Rubix Building Products

Simply put the 1x1x3 is a pseudo puzzle, It fills a gap in the collection but its not exactly complicated to solve. The way this puzzle was made was by using two centres and a core of a QiYi Sail. As these parts already spin like a 1x1x3 should all I had to do was make these parts into cubies by adding some apoxie sculpt and sanding them smooth. This puzzle was made in an afternoon and stickered the following morning while I was also building my 'Mefferts bandage cube'.
Puzzle makers have been creating problems for people to solve for centuries. Some of the earliest puzzles date back to the time of the ancient Greeks and Romans. The Chinese have a ring puzzle that is thought to have been developed during the second century A.D. This was first described by Italian mathematician Girolamo Carolano (Cardan) in 1550. When the printing press was invented, complete books of mathematical and mechanical problems designed specifically for recreation were circulated. Rubix Build
