How To Solve Rubiks Cubes 3x3x3 Fridrich F2l methood Easy Way

Fridrich F2L: Going Slow and Looking Ahead (Tutorial)



http://www.youtube.com/watch?v=jfE7jYOXbgg



I've made a tutorial on going slow and looking ahead. It shows/proves how important looking ahead is and how it helps, and tips on how to practice getting better at it.

This tutorial is mainly directed for people who's Cross + F2L is around 15-25 seconds, for those who have been trying to improve in Fridrich F2L but have gotten "stuck." I know that many of the information I talk about in this video is obvious, but since "newest cubers these days seem to be getting younger, less patient, and less respectful (Michael Gottlieb)" and won't understand if someone just simply tells them to "look ahead," I think this video will be helpful to those people.

You will usually see some person who knows Fridrich F2L and is stuck. They ask how to get faster and usually someone tells them to look ahead. In my opinion, that is very vauge. Evne if you explain that while you're solving one pair you should be looking at the next, I feel that it's still not specific enough. People probably will think that won't help them at all and will not do it. This is why I have gone into greater detail explaining looking ahead, and giving some example solves on not looking ahead and looking ahead.

I also think people won't know how important it is. You could say several how important it is, and they might think they believe it is important, but they truly do not know how important going slow and looking ahead is. I feel that it is very helpful if the person is shown and also proven how good going slow and looking ahead can be.

So I'm trying to tell experienced cubers that this tutorial is not totally pointless, as it is mainly only directed for people who have not or have barely heard about looking ahead, and I think this is a perfect tutorial from them.

I have a few people who have seen this tutorial already (mainly people's who's F2L is 20-25 seconds), and they have responded with positive feedback (not only in the comments). So I believe this video will be helpful to people, and it has been proven, so I would appreciate it if you do not call this tutorial a piece of junk. 

Description:

This is a tutorial on Going Slow and Looking Ahead in the F2L part of the Fridrich method. In this tutorial, I will talk about what Looking Ahead exactly is, how it's useful, and how to practice getting better at it.

Looking Ahead in F2L is one of the most important techniques in getting faster at the First Two Layers. In order to average under 20 seconds, it is imperative that you become very good at this skill. It will still help you in reaching sub 15 seconds times and even faster than that too. I cannot stress enough how important Going Slow and Looking Ahead will help you.

It is recommended that you average under 25 seconds for your F2L (F2L + Cross) before you attempt learning about Looking Ahead. If your F2L isn't under 25 seconds it really shouldn't be hard to get to that speed with some practice. I would also highly recommend looking at Badmephisto's F2L videos, even if you already average under 25 seconds for F2L. He talks about very important basic tips in getting faster at F2L that is definetly worth watching.

beginer 3x3x3 tutorial cube easy way

This tutorial describes a simple beginner method for solving the Rubik's cube, requiring memorisation of only one short algorithm. The tutorial is designed for complete cubing beginners. It requires no pre-existing knowledge of the Rubik's cube or any understanding of algorithm notation. Everything is explained in english. The general concept for this method comes from a method called 8355, but there are some modifications to improve ease of learning. 

The method is based on a short algorithm called the sexy move. In algorithm notation, the sexy move is R U R' U'. This translates into plain English as:

Rotate the right layer 90° clockwise.
Rotate the top layer 90° clockwise.
Rotate the right layer 90° anticlockwise.
Rotate the top layer 90° anticlockwise.

In order to keep reading to a minimum, the standard tutorial is presented in a short and concise style. A longer explanitory version is also available to provide a more detailed description of the steps:

The Steps

step diagram

Cross
3x Middle Layer Edges
3x Bottom Layer Corners
3x Top Layer Edges
Final Two Edges
3x More Corners
Final two corners




Terms used:

  • edgeA piece with two stickers. It is solved when both stickers match their neighbouring centre pieces.
  • cornerA piece with three stickers.
  • sideAny face which is not the top or bottom face.
  • frontThe front face of the cube is taken to be the vertical face closest to the solver.

Cross

cross
Solve 4 bottom layer edges by repeating these steps:

  1. Look in the top layer for an edge which belongs in the bottom layer. Twist the top layer until one of the edge's stickers matches a side's centre sticker. 

    If the side's centre sticker and matching edge sticker are next to each other, then twist the side 180°
    Otherwise twist the side 90°
    Now repeat this step for another edge. If there are no bottom layer edges in the top layer, go to step #2.
  2. Look in the bottom layer for an edge which belongs in the bottom layer but is not solved. 

    Twist the side containing the edge by 180° to move it into the top layer. Now go back to step #1.
    If there are no unsolved bottom layer edges in the bottom layer, go to step #3.
  3. Look in the middle layer for an edge which belongs in the bottom layer.
    Turn a side by 90° so that the edge moves into the top layer with its bottom face sticker in the top face.
    Rotate the top layer and then undo the side turn. 

    Now go back to step #1.

3x Middle Layer Edges

3 middle layer edges
Look in the top layer for an edge which belongs in the middle layer. Look at edge's side-facing sticker. Find the side on the cube with the same colour of sticker in the centre.

If the edge is positioned within the side, twist the top layer to move it away.
Turn the side 90° so that a bottom layer edge moves into the position that the middle layer edge will occupy when solved.
Now rotate the top layer so that the middle layer edge moves into the side which was just turned.
Undo the side turn.
If no middle layer edges are in the top layer, then move an unsolved middle layer edge into the top layer by turning a side-face 90°. Now rotate the top layer and then undo the turn on the side-face.

3x Bottom Layer Corners

3x bottom layer corners
Keeping the cross in the bottom layer, rotate the cube so that the last unsolved middle layer edge is in the front-right. If all the edges in the middle layer are solved, hold the cube with any middle layer edge in the front right. 

Look in the top layer for a corner which belongs in the bottom layer, but not directly below the front-right position.

Rotate the top layer so that the corner is in the front-right position.
Now rotate the bottom layer, so that the place where the corner belongs is also in the front-right position.
Now repeat the sexy move until the corner is correctly in position in the bottom layer.
If there are no bottom layer corners in the top layer, then rotate the bottom layer until an unsolved corner is in the front-right position. Do the sexy move once. The corner will now be in the top layer.

3x Top Layer Edges

3 middle layer edges
Rotate the top layer to align the side-facing stickers of as many top layer edges as possible. Always do this before inserting an edge, to check which edges are still unsolved.

Look at the top layer edge in the front-right of the middle layer. Imagine the 90° side turn which will place it into the top layer with the correct sticker facing up, taking a note of where it will be placed.

Rotate the top layer so that the edge will be placed into its correct position when the side turn is made.
Do the 90° side turn.
Rotate the top layer to replace it with another unsolved edge.
Undo the side turn.
If there is no top layer edge in the front-right position of the middle layer: Turn the right face 90° clockwise. Rotate the top layer to place an unsolved edge in the top-right position. Undo the turn on the right face.

Final Two Edges

3 middle layer edges
There are four possible scenarios:

  1. You're lucky and all the edges are solved! Go to the next step.
  2. The fourth top layer edge is in place, but flipped:

    Turn a side face to move the unsolved middle layer edge into the top layer.
    Rotate the top layer so that the flipped top layer edge replaces the middle layer edge.
    Undo the side turn.
    Now solve the edge as before and the final two edges will fall into place.
  3. The fourth top layer edge is in the front-right of the middle layer, and can be placed by turning the right face:

    Turn the top face so that the unsolved edge is in the top-front.
    Do the sexy move once.
    Now solve the same way as before and the final two edges will fall into place.
  4. The fourth top layer edge is in the front-right of the middle layer, and can be placed by turning the front face:

    Rotate the cube so that the unsolved middle-layer edge is in the front left.
    Turn the top face so that the unsolved edge is in the top-front.
    Turn the front face 180°.
    Do the sexy move once.
    Undo the 180° turn on the front face.
    Now solve the same way as before and the final two edges will fall into place.

3x More Corners

3 middle layer edges
Flip the cube over so that the top layer is now the bottom layer . Now rotate the cube so that the single unsolved corner in the new top-layer is in the front-right position. If it happens that all corners in the top layer are solved, just pick any corner. From now on the cube should not be rotated under any circumstances. Follow these steps:

  1.  
    Look at the corner in the front-right of the top layer. If it does not belong in the bottom layer , do the sexy move once and a bottom layer corner will move into that position.
  2.  
    Look at the bottom layer corner in the front-right of the top layer.

    Rotate the bottom layer so that the position the corner belongs in is also in the front-right.
  3.  
    Repeat the sexy move until the corner is correctly in position in the bottom layer. After doing this the top layer will probably look scrambled - don't worry that's supposed to happen!
  4. Repeat steps 1 to 3 until there is only 1 unsolved corner left in the bottom layer.
At this point the top layer probably still looks scrambled. To unscramble it, rotate the bottom layer to position the final unsolved corner in the front-right. This time, repeat the sexy move until the top layer looks mostly solved again. If you're lucky the cube will now be solved completely, but normally there will be two unsolved corners remaining.
Before moving onto the final stage, ensure the last unsolved corner in the bottom layer is still in the front-right position. Do not align this layer until the end of the solve.

Final two corners

3 middle layer edges
These are solved in a similar way to the first three. First rotate the cube so that the final two unsolved corners are in the bottom layer, occupying the front-left and front-right positions. Again, do not rotate the cube during these steps:

  1. Do the sexy move until the front-right corner in the bottom layer is solved.
  2. Turn the bottom layer to position the last unsolved corner in the front-right.
  3. Repeat step #1.
Align the layers to complete the solve.



If you're now holding a solved cube, congratulations!

How to solve rubik cube 3x3x3 easy way


Rubix Cube Solution INTRO TO PARTS 1 to 5

Well, now that you have experienced the challenge of Rubik's cube and lost, you know why we say it's so perplexing. Chin up! In order to help you regain your sanity, we have developed the following simple approach to the ultimate rubix cube solution. 

Take heart, with a little practice and some memorisation we will soon have you dazzling your friends, relatives and total strangers with your new found mastery of Rubik's cube.

The solution to Rubik's Cube requires concentration and faithful attention to the detailed instructions in each part. It should take you about an hour to read the direction and solve the cube mechanically. However, if you repeat the process several times, you will begin to understand how and why each group of moves work. You may even develope your own approach to the solution.

We suggest that you memorise the groups of moves so that you learn to solve the cube without the directions. Once you can solve it on your own, the fun really begins as you try to do it faster and faster. Rubik's cube can be solved in 2 minutes flat, so have fun.

To solve the cube, you must understand first all of the component parts of the rubix cube and master a few basic moves.

1. THE CUBE

Basic Cube Parts - Rubik's Cube ia a deceptively innocent looking 2 and a quarter inch cube with over 3 billion possible colour combinations. It has 6 sides, 6 colours, and 26 smaller sub-cubes (see figure A).



There are 8 corner pieces with 3 colours, 12 middle edge pieces with 2 colours and centres with 1 colour each (see figure B). In the ultimate solution, each sub-cube has only one correct location.



2. PERSPECTIVES

First, to make sure we are looking at the cube in the same way we must agree what to call each side:





All turns are either 90 degrees (1 turn) or 180 degrees (2 turns).

3. COLOUR ALIGNMENT

Colour alignment is an important concept to understand, and it is illustrated in figures 3A and 3B. A completed cube (A) has all its pieces colour aligned.



Now imagine popping out one sub-cube, then putting it back in with its 2 colours reversed. This piece would now be in correct position but not colour aligned (see B below)



4. HOW IT WORKS

A. The cube can be manipulated by rotating rows vertically or horizontally, and just a few simple turns are required to produce a completely random pattern of colour.








B.a) The centre square on each side determines the colour of that side (see fig (A) below)




b) No matter how the colours are mixed, if you were to hold your thumb and forefinger on opposite centre pieces, they would show you which colours appear opposite each other on the cube, eg. if left centre is blue then right centre must be green. (see fig (B) below)



Note: This may vary from cube to cube since each cube may be labelled differently.

c) In order to solve a side you must move certain cubes from vertical to horizontal planes, to line up rows of 3 sub-cubes of the same colour. Note: one turn moves a sub-cube 3 places, and 2 turns will move it 6 places











5. THE OBJECTIVE

The objective is to return all 6 sides to their original solid colours, and there is lots of satisfying fun along the way as you solve one or more sides to create interesting new patterns of colour. Here are the levels of skill you can attain.
