Possible Problem:The corner you are looking for is in the top layer, but in the wrong position or turned the wrong way around. Turn the cube so that the corner is in the front right top corner then move the corner to the bottom layer by following the following steps.

Possible Problem: None of the corners is in the correct position. Solution: Perform the steps in (A) once with ANY side facing you (YELLOW at the top). Now one corner will be in the correct position. Proceed with (A) above.
The first speedcubing World championship was held in 1982 in Budapest and it was won by Minh Thai (USA) with a 22.95 seconds solution time. Since then the methods have evolved and we are capable of reaching solution times below 6 seconds. If you want to improve your cubing speed, all you need is a high quality, well lubricated Rubik's Cube with good corner cutting and optimal tensioning so the pieces don't pop. Practice finger tricks, the art of turning the cube like you can barely see the movements. You'll also need a Rubik's Cube timer to keep track of your evolution, and a lot of practice of the method described in the tutorial below.
When talking about the advanced technique of solving the Rubik's Cube we have to mention the Petrus system and the Fridrich method (or full CFOP) which is used by the big majority of speedcubers these days. This advanced technique developed by Jessica Fridrich divides the puzzle into layers and you have to solve the cube layer by layer using algorithms in each step, not messing up the pieces already in place. These steps are the following: Cross, F2L, OLL and PLL, as seen on the illustration above.
1. First of all we have to solve the white edge pieces in the bottom. This seems to be the easiest but it's really hard if you want to do it right. You should be able to determine all the rotations needed to complete the white cross after inspecting the cube, and you'll succeed only if you foresee 7 steps.Read more >>
2. When the cross is done we solve the first two layers (F2L) in one step using a technique to pair the white corner and second layer edge pieces. We are talking about four corner blocks which usually require 4x7 steps.Read more >>
3. Orienting the last layer (OLL) of the Rubik's Cube is the step in which we solve the yellow face without matching the side colours. We are going to position them in the next step. Learn all the 57 algorithms to complete this step.Read more >>
F2L is not that hard to understand at first, but practicing it is where most of your time investment will be. There are many different situations to recognize, and finding 2 pieces at once is definitely a step up. Expect to be slower at first since it's harder, but over time you will be much faster with F2L compared to the beginner method.
This step aims to solve a 1x2x3 block on the left, but that can, of course, be rotated to be on the right hand side. This step is usually done by either inserting the DL edge, then solving the two F2L pairs around it, which is usually inefficient, or blockbuilding, which tends to have more moves that are not ergonomic.
Beginners to cubing or to Roux tend to use the former way, but the latter way is better in the long run, and can usually be solved mentally in the 15 second inspection period allowed to you by competition organisers. This step should take about 7 or 8 moves if you always solve it in the same place using the same pieces.
Second Block is the second step in this method. It is the same block as the first step, but on the right. This step has more complications than the first step, as you need to solve it without breaking the already solved first block.
CMLL is a step that is pretty similar to COLL, but with one key difference: it does not care if the M slice is solved. This means that algorithms can be shorter. However, it is possible to use COLL algorithms for CMLL, but not the other way around. There are 42 algorithms, and it is recommended that you learn all of them, but you can also just use sune and anti sune to orient the corners, then use Jb and Y perms to position them.
Next up is their latest offering, LEGO MINDSTORMS NXT Thinking Robots (No Starch Press, Dec 09, 224 pp., $29.95, ISBN 9781593272166), an intriguing new title that shows how to build a tic-tac-toe playing robot and one that actually solves a Rubik's Cube. Readers will find detailed, step-by-step instructions for building each model with either the original NXT or the NXT 2.0 set, as well as a discussion of how each robot works, how they "think," and how to play with them. 2ff7e9595c
