This small program was designed to generate randomized scrambles for all 41 basic 3x3 rubiks cube f2l cases, from all 4 angles fr, fl, bl, br. Many of these cases are very similar to each other mirrors and therefore. Unlike the ll last layer, where the algorithms are pretty much determined and all you need to do is to quickly recognize a fixed set of positions and memorize the algorithms, the f2l can be done in many different ways depending on which corneredge pair you spot first. They are applicable to all f2l slots when reflected accordingly. You can sort this list by shape, trigger, and number order, to facilitate easy finding of a specific situation and memorising of the whole list. Each lower case letter means that you have to move two layers at the same time. So you only need to understand a few concepts and you will have learnt f2l. For the type 1 cases, the corner is moved into the bottom layer so the edge can be moved without disturbing the corner. We dont care if the side colors dont match, we are going to permute the last layer pll later. It takes 20 unique scrambles from cubeexplorer, all scrambles roughly 711 turns in length.

While solving, you will meet the same cases again and again, so does it just mean to figure out the algorithms by yourself.

Now these algs are only for inserting into the right front slot, but they. Fridrich method was invented by jessica fridrich of czech republic in the. As familiarity with f2l improves it may be desirable to optimise some of the more difficult cases, for example where the desired cubies are connected incorrectly. If you need to swap opposite edges, you can use this algorithm. Use algorithms to help you understand each concept. Once the bottom two layers are solved, the top is typically solved using oll and pll. This page lists all nonjeff2l standard f2l cases from every angle, focusing on rotationless algorithms.

The 41 possible cases in this step can be solved intuitively but its useful to have a table of algorithms printed on your desk for guidance. The whole point of intuitive f2l is that there are no algorithms involved. This page first lists algorithms for each of the 41 standard f2l cases with target slot fr. Turning the whole cube in your hands is a 3xx3 waste of time. Well thats natural because everyone spends a lot of time to track the edge pieces when they are starting out. Maybe youre even getting pretty good, and can consistently do it in under 2 minutes. However, the problem is finding each of the algs, and writing them down into a format that is easy to access. U, r, l precisely when it has a good edge, which explains the terminology since rl are prefered in speedcubing over fb.

The cases described below are designed to help you gain that intuition. Especially, what is the difference to solving f2l with algorithms. There you take a corner of the first layer and the correct corner of the second layer, build with them a f2lpair and place them in the correct slot. Just practice for some time everyday, youll definitely improve. There are 41 different variations for solving the corneredge pieces in the f2l step. Simply learn the three triggers, and you nearly know most of the algorithms already. F2l algorithms different slot positions cubeskills toggle navigation.

Many of these cases are very similar to each other mirrors and. One the pairing of the corner and edge aka f2l pair and two the insertion of the f2l pair. Cfop is the most frequently used speedsolving method for the 3x3x3 cube. Orientation of last layer and corner permutation ollcp is an experimental ll method which both orients the last layer and solves the corners. But i can tell you how to go about intuitive f2l and some tips to get better times while using it. This involves remembering a lot of algorithms to cope with different situations, so i use some 2look oll and pll to reduce the amount of algorithms i need to know. This process should be learnt intuitively, but these algorithms will help improve efficiency.

For many cases with good edges to fr or br slots, the standard algorithm is in u, r, which partly explains why edgecenter matching occurs in many f2l algorithms. Cfop refers to the steps involved cross, f2l, oll and pll. In cases 05 and 06, it is sometimes useful to use a working edge to place the corner. This tutorial sheet shows you efficient ways to insert f2l pairs into all four different f2l slots around the cube. F2l algorithms different slot positions cubeskills. This picture was created for a instruction, how to solve the rubiks cube with intuitive f2l, thats a method to finish the first 2 layers. Do not underestimate the progress you can make by just looking at the cube and trying to figure out the cross. Fridrich f2l pdf there are 41 different variations for solving the corneredge pieces in the f2l step. Although my f2l is now much better, these cases remain hard. Easy cases 14 u r u r use r f r f if no u face edges are oriented properly on final slot y u r u r. The core blockbuilding techniques introduced above are the minimum requirement for completing f2l intuitively. Since most people including me like to have a printed version of the algorithms they want to learn, i also made one single page with all zb f2l cases listed on it. The moves are based solely on intuition, so algorithms are not required.

Ive made a pdf of in my opinion are the best f2l algs for every case. In the second step of the fridrich method we solve the four white corner pieces and the middle layer edges attached to them. Only a very few number of people use the full set, but a number of people use the subsets coll and cllef. Andy klises speedcubing guide algorithms by dan harris and erik akkersdijk first 2 layers you must solve the cross first. Best algorithms for all advanced f2l cases pdf j perm. Some of them seem odd, like cases 1, 3, 4, 8 and 9. When done at full speed, f2l can be completed in less than 10 seconds. F2l algorithms first 2 layers developed by feliks zemdegs and andy klise images sourced from conrad riders visualcube. F2l combines steps 2 and 3 of my beginner solution, but it requires approximately the same number of moves as step 3 alone. Rubiks cube advanced fridrich orient last layer oll. In theory, there are so many unique f2l cases that memorizing them all would be a very slow way to learn it. While solving the rubiks cube with the advanced fridrich method, when the first two layers f2l are solved we need to orient the last layer oll so the upper face of the rubiks cube is all yellow. Generates randomized scrambles for all f2l cases from all angles. Advanced method this is full cfop or fridrich method.

Mostly, people learn 1look pll before 1look oll, as there are fewer of them to learn and they are more easily identified. You should check the algs for any thats over ten moves long. March 9, 2012 february 3, 2018 adventures in cubing.

This method was first developed in the early 1980s combining innovations by a number of speed cubers.

From beginner level to pro level, f2l is usually the step with the most room for improvement because it requires recognizing and tracking multiple pieces at once, while having quite a lot of freedom.
