Use this application to play with the Rubik's Cube online. Hit the Scramble button and try to figure out the solution yourself rotating the faces with the buttons or with your keyboard.
The app is using the open-source Kociemba algorithm to find the solution in 20 steps for any valid scramble. For slower computers the program automatically reduces the computing performance to return a little longer solution.
Start by selecting the most suitable view for you with the little tabs above the cube. The default 3D view can be customized, setting transparent front faces or you can lift the hidden faces. Rotate the cube with the arrows or swiping the screen.
The easiest way is to use the color picker. Select a color on the palette then paste it on the surface of the puzzle. Click more than once on a field to deactivate the color palette and cycle through the colors as you keep clicking the fields of the puzzle.
Do face rotations on the puzzle using the rotation buttons or pressing the corresponding buttons on your keyboard: L, R, U, D, F, B. The capital letters indicate a clockwise rotation of each face: Left, Right, Up, Down, Front, Back. It makes a counterclockwise turn if the letter is followed by an apostrophe.
Execute or play back a scramble algorithm in the allocated input field. Copy-paste the list of letters because the program might execute the rotations as you're typing them directly in the field. Mark reverse rotations with lowercase letters or single quotation marks (').
When the scrambled colors are properly configured and are matching your Rubik's Cube click the Solve command to get the solution. The cube solver will alert you if your configuration is not correct.

Let's start with the white face. Try to form a plus sign on the top of the cube, matching the colors of the side stickers to the colors of the lateral centers. This step shouldn't be too hard, try to do this without reading the examples below.
First put the white corner that belongs to the spot marked with the upper arrow in either of the highlighted positions. Next repeat the algorithm below until the white piece comes to its desired destination.
Turn your cube upside down because we don't need to work with the white face anymore. We can insert an edge piece from the top-front position to the middle layer using a trick. Do the left or right algorithm depending on which side you have to insert the piece:
1. Hold the cube in your hand having an unsolved yellow corner in the highlighted top-right-front position.
2. Repeat the algorithm until this piece is solved.
3. Turn the top layer to bring another unsolved piece in the highlighted position.
4. Repeat R' D' R D until that one is also solved.
5. Do 3 and 4 for any other unsolved yellow corner.
After building the Pocket Cube Solver I wished to expand upon this design and cater for a conventional 3x3x3 Rubik Cube.In this post I wish to discuss the process I went through in designing and building the solver and visual client alike - taking the learnings garnered from implementing the previous solver.
Along with conventional Layer by Layer approaches that eventually get you to the solved state, there has been much research in the space of producing algorithms that perform this result more efficiently.
With multiple different algorithms available to solve a Rubik Cube, I decided to architect my solution in such a way that could cater for multiple different solvers being plugged in to the same cube represenation - achieved using Rust traits.This would allow me to explore the advantages and disadvantages of each algorithm going forward.I also applied the same level of design to the cube itself, knowing that in each algorithm, certain different aspects of the cube were of concern.
Similar to how I achieved the visualisation for the Pocket Cube, I was able to take advantage of much of the same model of which had been built in that solution.Using a combination of React, Three.js, react-three-fiber and TypeScript I was able to expand upon the 2x2x2 design already built, and add the necessary additional cubies and rotation animation amendments required.I was very pleased with how the previous work completed in building the Pocket Cube could be brought over and expanded upon to increase the scope of this project.
Rubik's cube is among the most loved and popular puzzles. It might seem quite an intimidating challenge for some, but that does not need to be the case. If you have some trouble solving the Rubik's cube, don't give up just yet.
All you need are a few algorithms (that we will cover later in this article) and sheer determination to solve the cube. The easiest way to learn to solve a cube is to follow proven guides and tutorials.
In this beginner's guide, we will walk through the steps to solve the cube, with notations and descriptions of the algorithms that you would need to memorize. But before we jump right in, let's get familiar with the terms associated with the Rubik's cube.
Similar to the first step, solving the second layer also involves four pieces. However, instead of four corners, it now encompasses four edges. Therefore, you need to first search for the edges. Remember that the color of the piece that you are looking for should match the center. To position your pieces correctly, you must keep that face to your right, then see if it should be placed in front or at the back.
These algorithms will help you get the desired edges into their positions. You can repeat this algorithm until you get the desired edge colors placed in accordance with the color of the centerpiece. This will help you finish solving the second layer.
Match the colors to the face they belong to, and keep this solved face to your left. What you will then have on the face is an unsolved corner on which you should perform this T-Perm algorithm. You can repeat this algorithm until all the corner pieces are solved.
Once done, you need to look for two corner pieces that are adjacent to each other and are solved. Match those corner pieces with their centerpiece, position them towards your left, and perform the T-Perm algorithm.
Note: To execute this algorithm, find one edge piece that has been solved. Orient that with its centerpiece and hold it at the back. The three remaining edge pieces will have to be rotated on the top layer. You will notice that the pieces need to be moved in a clockwise Or counterclockwise manner. Execute this U-Perm to complete solving the remaining pieces. You may need to apply it twice in some of the cases.
And there you have it! There is no denying that you might need to invest a considerable amount of time to get the hang of it. However, master this beginner's method before you move on to learning any advanced methods. This beginner's method will create a great foundation for you to understand the working of the cube and the seamless movements of your fingers. Thereafter you can move on to learning finger tricks that will help reduce your average time.

So I'm building a machine to solve a Rubik's cube but I'm not sure what motor I should use. I need one that is moderately fast at about 60-180 rpms (.25s - .0833s per 90 rotation)and needs to be very accurate as I need precise 90 Rotations. The motor also needs to be limitless and somewhat cheep as ill need 5 of them. Hopefully less than 10-20$ per motor. Also if it could run off of a battery that would be awesome as I can really only get 5v with the equipment I have. I'm not sure if there is an ideal motor for my guidelines but I'd be happy to look into any suggestions that you guys make and make adjustments to what I can get.
With the cube being attached by all the cores all the algorithms I make and use are going to place all of the pieces in the white face without messing it up. And then when the white face is solved it doesn't need to be moved. I don't have a diagram of it but if been working in this project for a month or so and made sure it can work
His project is really cool and I like the speed of his motors the only problem with them are that they aren't limitless. I saw one of his videos and after every turn he pulls the motor back to reset the motors position. The way I've designed my base it wouldn't be able to move.
Most robotics use stepper motors. They are "slow" but you can probably get 1000RPM. But speed can be tricky.... Because of inertia you might have to accelerate instead of starting at full-speed. If you start at maximum speed and it doesn't make the first-full step, it won't run at all. You also need at least one home-sensor so the software can find the starting-point, and then you simply count the steps (in either direction)
A servo is an angle motor and it doesn't go 360 degrees. (There are full-rotation servos but they are not true servos and they are not accurate.) A regular servo an be can be geared-up to make one or more full-turns but you lose torque and precision.
