Weird Dead End Using Cubicle 3x3 Guide

[scullymerlin]

I'm having a strange issue using the 3x3 Beginner's Guide published by the Cubicle (https://thecubicle.us/3x3Tutorial.pdf) on one particular cube, but not on others, and I'm very confused as to what is happening. I am proficient at solving cubes using this method, but cannot solve this one particular cube. Each time I try, the cube ends up resulting in a configuration that cannot get past the step titled "Twisting the Last Layer Corners" (where you twist the corners of the last layer so that the yellow side faces down). Each time I reach that step on this particular cube, the final corner ends in a configuration that cannot be twisted downward using multiples of the right hand algorithm without spoiling the rest of the cube. Here is an example of the configuration it creates:



In this instance, the problem corner is the red/blue/yellow shown in the top-center image, which I am trying to rotate so the yellow faces toward the yellow side.

Does anybody have any idea why this is happening? I'm sure somebody more skilled than I could solve this easily, but I only know how to solve the cube using that basic algorithm, so I keep getting stuck. I've tried this again and again on the same cube and always run into this issue at the end, but my other cubes solve normally. So confused!

Thanks for any help!

It is clear from the photos that one of the corners got physically twisted in place. It is impossible to solve without twisting a corner.

Your cube looks modern enough that it should be possible with some force to twist that one cube in place clockwise so that the yellow side of the cube matches the rest of the yellow side. At that point, your cube should be solvable.

I concur. Whenever there’s a cube that you just can’t solve, you should physically twist the cube. It won’t harm it and you’ll be able to solve it!

Or you can peel the stickers. Always works

You have a corner twist which makes it impossible to solve. To fix:

1. Rotate the face with the twisted corner 45 degrees(half turn)
2. Twist manually into the correct orientation(facing the same way as all the other ones.)

Thanks all! This was extremely helpful. I didn't realize the corners could be twisted like that. I really appreciate all of your replies!
