new blindfolded 3×3 world record

Adventures in CubingLeave a comment

As Gizmodo reports, there’s apparently a new (blindfolded) sheriff in town. Hungarian Marcell Endrey clocked a 28.80 3×3 blind solve at the Zonhoven Open in Belgium, shaving two seconds off the previous record of 30.58.

Even more impressive, the 28 seconds includes almost 13 seconds of inspection time. In other words, it was a 15-second blind solve!?!

Looks like a stickerless Dayan — which is illegal in normal competition (since you can see four sides at once). I guess that concern doesn’t exist when you put on a night shade….

XY1 Tackles the Cube

So, after a couple months of simply watching me cube, my four-year old today asked me if he could solve it.  He took to it like a champ:

Funny how the cube locked up at 0:19 when he was trying to do L’.  After a few seconds, he settled on 3 L moves.  Creative.

STEP 4: Permuting the Last Layer (PLL)

The good student you are, you’ve now studied the Cross, First Two Layers, and OLL Beginner’s Method tutorials.  If you followed them closely, your cube should like this.  The bottom face should be all white, the top face should be all yellow, and the first two layers should be solved.  The last layer, indicated in gray, is likely to be a bit jumbled.  (There is a 1/16 chance that the previous OLL step actually solved the cube completely.)

The goal in this last step is to orient (“permute,” in cube-speak) the last layer pieces into the correct positions without disturbing the top face, bottom face, or first two layers. Continue reading →

STEP 3: Orienting the Last Layer (OLL)

So, you’ve pored over my Cross and First Two Layer tutorials, and have successfully made your cube look like this?  Well done!  Believe it or not, you’ve done the hardest parts.  The next steps of completing the top face (OLL) and then correctly permuting the pieces to complete the top layer (PLL) are significantly easier.  They require a bit more memorization.  But don’t be intimidated.  I had thought that I’d never memorize these algorithms.  Now, just three months later, they are so much a part of my muscle memory that it was actually hard for me to slow down to transcribe them.

With the bottom face all white and next two layers solved, we know all of the pieces in the top layer will have yellow on them.  In this step, Continue reading →
