To solve it, just do the above algorithm one more time, and you should have oriented all of the top layer. The notation for each of these is U, D, L, R, F and B respectively. Orientate the cube so that this corner piece is in the top right of your front face. Think of the algorithms as moving a piece out of the way, setting up its correct position, and then moving the piece into that place. The algorithms are divided into groups based on their effect on the Rubik's cube (corners only, edge only, etc...). You might have two corners oriented or none oriented. For example, your cube could look like the one pictured. The centre pieces on each face, as you may have noticed from playing around with the cube, can't be moved to another spot, only rotated. The New Rubik’s Speed Cube – Engineered for Speed With Magnets The Cube can be solved in twenty moves, but how fast can you do it? You will need to line it up like in the picture. F) means turn that face 90 degrees clockwise with respect to the center of the cube. In all cases, make sure you orientate the top row so that at least one of the pieces will end up on the correct side of the cube. This shows you have Sune. To begin with, hold the cube with the yellow center on the up face. You may wonder why do you need an algorithm here, but if you are a more serious user of Rubik's Cube, you must know that a Rubik's Cube is based on different algorithms. At all times, bear in mind the bigger picture. You're done with all white pieces, so you can now flip your cube so white is on the bottom. Algorithms can seem daunting to read at first, but they are pretty simple. * The Corner Switch: R=CC, F=C, R=CC, B=2, R=C, F=CC, R=CC, B=2, R=2. I would love to hear how fast you can solve a rubik’s cube. The best centre to build your first cross around is the white centre, as many guides and resources on the web start with a white face, so if you need to look up some steps and examples elsewhere, your cube will look similar to the one that is being used in other demonstrations. Congratulations! You will likely need to do this a few times, keeping the same reference corner piece in the top right -- it will return to the same position when the algorithm is complete. 3 Rubik’s Cube Algorithms to Solve Common Tricky Situations. This is essentially what algorithms exist to do. For all algorithms provided, it is important to try and visualize the block moving around, and why the move is being made. For the one case without headlights, just perform the algorithm below from any angle. When following the algorithms in this guide, it is important to maintain the FRONT face of your Rubik’s Cube so it stays the FRONT through all of the turns. If you need some help with those pieces that are in the top row but not orientated properly, you can flip them using the following sequence: -. If you need to move it to the left, here is how you do that. This is only seen in one case of the 21 though, so you won't see it often. The first thing to do is to get them into the right spot. In many cases, according to some sources, it should be possible for the average person to complete a Rubik's cube in around 20 to 25 minutes. Either none, all, or two of the edges will already be oriented correctly (the yellow part is facing up). By subscribing, you agree to our Terms of Use and Privacy Policy. With an algorithm, you can make your Rubik’s cube solving fun. If you are struggling with other scenarios, check out any of the full tutorials we have provided above to help you out. Hold this at the back. As you can see, the orange piece matches the orange centre. Algorithm 3a: Ui Li U L U F Ui Fi Algorithm 3b: U R Ui Ri Ui Fi U F Shuffle Algorithm: L Ui Li Ui Goal: To complete two bottom lines on all four front, right, left, and back faces.Like below: 2nd layer; How to do it: Who knows, you may become the next Guinness World Record holder? Beside the solved cross you can also have a “Dot”, an “L” shape or a “Line” as pictured above. Sune and Antisune are two of these, but we won't always get them straight away. We'll dedicate the rest of this article to showing you these algorithms, in order to complete the above "master plan" algorithm. If the corner is on the bottom of the puzzle, perform the required D moves so that the corner is in the position marked in pink on the picture. You're 1/3 done (kinda)! So, are you ready to join the 6% who have solved the Rubik's cube? I have taken care to choose algorithms that I think are easy to both memorise and perform, and I have arranged them in an order that I think facilitates learning. Is solving a Rubik's cube using algorithms? Never solved a Rubik's cube? Using basic group theory, the reason these solutions are not incredibly diﬃcult to ﬁnd will become clear. For most of the process, the "top" layer will be your "working" layer where you move pieces around and then "drop" them into the lower layers, with the exception of this stage and the final stage (as they are the "top"). 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. Hold the cube in your hand and choose one of the corners to start the process. It takes, on average, about 45 minutes, or so, to learn these moves. The Rubik's Cube can be very frustrating and may seem next to impossible to restore to its original configuration. Perform this algorithm as many times as is needed to put the corner in its place: Top Below are the letters of the basic moves: F. Front face. Take your cube and perform the following short algorithm: U' L R2 D B' F U2 R'. Either the two matching edges are adjacent (next to each other) or opposite each other. There is a 50% chance it will be on the bottom layer. For the “Dot” case shown in the first picture, just do either of these algorithms to get a different case. Since this is the simplest stage, it is highly recommended you attempt to do this through trial and error. The aim here is to produce a cross, usually called the "white cross". match the fixed centerpieces on each side). The next will move these pieces around and thus solve the cube. Well done, you are 66% of the way there. To denote a sequence of moves on the 3×3×3 Rubik's Cube, this article uses "Singmaster notation", which was developed by David Singmaster. If you need any extra help look at Derek Tia's guide. This article needs to be cleaned up. We'll dub this the "move-to-the-right" algorithm. Although the whole cube group is very large (~4.3×10 19), the right coset spaces ∖, ∖, ∖ and are much smaller. A special notation is used to describe which face needs to be rotated in which direction. Below is an example of getting one into place from our real example. Repeat until you have either two or four edges matching their centres. Rubik cube is one of the most famous gaming products when it comes to brain teaser games. Then perform this algorithm: If done correctly, you should now be looking at the yellow cross. There's a very small chance that there won't be any, but there are instructions for that case below. Then apply this algorithm: F R' D' R F2. There are six sides on the puzzle, referred to as faces, all of which can be turned individually: Up, Down, Left, Right, Front and Back. The first thing you want to do is get the white plus on top. Each face of a Rubik's cube has a "name" or letter in relation to how you are facing and holding the cube. Algorithms (algs for short) are a set of moves that are done in a specific order to achieve a specific end result in orienting or permuting the pieces on a Rubik's Cube. Follow the following steps depending on where the corner is for you. This is how your cube will look like. To transform the Magic Cube from one state to the other, you have to apply the following short algorithm, watching out for the L shape and the line to be positioned as required: If you are in a hurry you can speed up the process by doing two jumps at once with this: When you have an “L” shape, where the two yellow pieces showing are adjacent one another. I suggest you to start with the corners in the bottom layer because solving these first might pop out some white pieces from the top layer and you might save a couple turns. Using this algorithm on higher order cubes can create additional cubes within cubes patterns as well. Once your cube looks like the image on the right above, move to the next stage. Each method is used to solve a standard 3x3 Rubik’s cube to determine which algorithm would take the least number of moves within the least period of time. The methods you will use, on the grand and micro-scale, will be by following some set procedures, aka algorithms, to complete the cube. You can swap them around by performing the following algorithm. However, the satisfaction of holding a completed Rubik's Cube in your hand and thinking “I did that, and I can do it again” is greater than most, mainly due to the fact that the puzzle has been present in all our lives at some point. Algorithm 3a: Ui Li U L U F Ui Fi. Rubik's Cube Solver. 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). A letter followed by the number 2 (F2) denotes 2 turns, i.e. To get an edge out of somewhere it shouldn't be, just insert one of the yellow edges into that slot. Once complete, turn the cube over so the white face is on the bottom. With the middle, or second, row complete, it is time for the most complicated part -- the top layer. For this stage, don't obsess over getting yellow edge pieces in the correct order. Now perform the following algorithm until the piece is orientated correctly. If none of them match, do another U move. Look on the bottom layer of the puzzle. The most common way to express a Rubik’s Cube algorithm is using Basic Notation, which is depicted below. Click on a cube to jump on the page to the selected chapter: An important thing to note is that this task is not a light one. However, once you know a few algorithms, it is very easy to solve. For this, we need to look at the front of the cube. In fact, according to some estimates, only 6% of the population have ever achieved it. Remember to hold it at the back. Now you know how to solve the Rubik's cube. Your goal is to have all four edges matching their centres. This is the last step. In fact, it took the inventor of the Rubik's cube, Erno Rubik, one month to learn how to solve his very own creation. Find a piece that already happens to be in the right place (its three sides match the surrounding colors on the cube's edge). Make sure it is in the correct position (aka the surrounding cube face colors are the same as those, in any order, on the corner piece). It doesn't matter if all of the white bits are facing up or none of them are. Like below: 2nd layer; How to do it: 1) Turn the cube upside down so that the white face is now the bottom face and the yellow face is … You will not be touching it for the next stage. But don't worry! Set up the scramble pattern, press the Solve button and follow the instructions. That's a good sign… right? This algorithm will flip the edge so the white part is facing upwards. Keep in mind that there are faster methods, but it is quite advanced and does require quite a bit of algorithm learning. In order to solve a rubik’s cube you just need to know the algorithm’s and this is the hard part. When you have the white cross, move to the next stage, but only if the edge pieces are in the correct order (i.e. Remember, whenever completing these algorithms, always keep the front face in front of you and never move the cube as a whole. When it is solved, one of the sides appears to be scrambled. A list of algorithm notations are listed below. We'll call it the "move-to-the-left" algorithm. Alright guys, hope that helped you for what are the fastest algorithms for the 2×2. The Rubik’s Cube is a fascinating, timeless puzzle with quintillions of possible states. A special notation is used to describe which face needs to be rotated in which direction. If you'd rather just solve the cube in your hand and forget about it rather than being able to solve any cube you're given, there are plenty of solvers available on the web. The upper bound gives an asymptotically optimal algorithm for solving a general Rubik’s Cube in the worst case. If you have a set of headlights on each side, ignore this part and read the section titled “The U Permutation”. You can solve the Rubik's cube too.
