This is a PDF from a video Felik’s made for his channel, CubeSkiils. This is the source of the. For people who love any sort of geometric puzzles, including but not limited to: Rubik’s Cubes (and any size/design variants), the Square 1, the. Hey guys, so I’ve been watching many advanced F2L tutorials, and I didn’t want to keep going back to the video to find a specific case they.

If one or both pieces are stuck in another slot, you can simply move them out by inserting random pieces from the top layer into that slot. Consider this situation, and the two approaches to solving it:. Lightweight and comfortable in the hand. Use the empty slot to form a 2x1x1 block and place the block into the slot in which it belongs. This database is part of the speedsolving.
Menu 1 Fridrich method: This will correctly permute one of the edges, allowing you to solve the rest with one more use of the above algorithms. However, many other sites do have so-called “algorithms” for this step. The learning can seem long and hard, but do not give up.
Some cases do not have pairing-up or insertion stages and will be shown in the normal black font. Well here is where your journey begins. Three different cases can happen here. They were used the one after the other in the step 7 of the beginners method. Every second you do not rotate any face can be saved. There are, however, a few situations you might find yourself in where this procedure is not quite so obvious. The cube is finished by permuting the pieces on the last layer so they are all in the right spot.
Not logged in Create account Log in. Break up the two pieces so that they become opposite from each other and then just place them. Ignore the algorithm if you are just learning F2L. Indeed, the whole cross is assembled on the bottom layer instead of the top.
Or you can check the advanced F2L section. SpeedsolvingFMC Previous state: You now know the basic ideas of F2L. In the diagrams of the cases made with Lars Vandenbergh’s amazing ImageCube scriptonly three sides can be shown, so sometimes, stickers from the edge cubie will be hidden from view.
You will also have noticed that the first two brackets are written in red. A total of four corner edge or ‘CE’ pairs are made and inserted to solve the first two layers. Corner In U-Layer With Cross-Color on U-Face In these cases, the corner’s sticker with the cross color will be on the U-face, making the corner completely “upside-down” of where it needs to be.
This method is named after its creator, Jessica Fridrich. Algorirhms can be quite difficult certainly so if you’ve only just started doing it upside down but with practice it will become very easy to isolate only the four edge pieces you need and formulate a basic plan to get them into a cross.
Both algorithms solve the F2L pair and use the same number of moves.
For example, consider the following two algorithms:. Don’t start by learning those algorithms. The idea of F2L is to pair each of the four bottom layer corners with the corresponding edge piece and then insert them into the correct place. I would advice you to get one of those, best speed cubes on Amazon. Much like the Sexy Move highlighted in red before, the sequence R’ F R F’ is a trigger called the Sledgehammer, and you’ll spot it lurking about in other places and algorithms.
Next, remove the corner from the slot to match the edge, AUF again, and place them both together. Just put the solved face in front of you and you will need to permute the three remaining edges. F2L Simultaneously solving the first two layers.
Case 6 Corner on Bottom, Edge in Middle. Page actions View View source History More. Slgorithms can be a little difficult to get your head around. Algorithm helper Toggle algorithm helper.
Secondly, try to minimize the number of times you flip the whole cube during the resolution. Please note that you will need Adobe Reader to access and print the printable page. Not having to turn the cube over after completing the cross on the top layer saves a lot of time, and it also means that you can be looking for the pieces for the next step whilst completing the cross on the bottom.
You are now ready to be a speedcuber with your knowledge of the Fridrich method. I shall now try to explain some further concepts that you can use to improve your F2L.
Simulating moves mentally will help you for the next solves and you will become more and more familiar with efficient cross solving. It has to be maximum once per pair, ideally just once or twice during the whole solve of the F2L. The goal with this step of Fridrich method is to solve the cube. Every algorithm will save you time.
Most of the time, what slows you down is your inspection and your thinking. This stage will be shown in green.
This is the fastest and the easiest Rubik’s cube solving method.
