Go for it Mike! When's your next WCA comp with multi?

Unfortunately it may be a while. There's one in Wisconsin in October that I'd love to go to, but I probably have a family-related conflict that will keep me from making it there. :-(

I wanted to ask a 6x6 edge/OLL parity question.

I have this case. If I fix the yellow/blue edge parity I end up with an OLL parity. Is there a different 6x6 alg that fixes this edge and prevents the OLL parity?

I just use the OLL parity alg with a slight modification to use 4R at one point (similar to the 5x5 version with 3R). Then I have to redo essentially the same 4x4 alg to fix the OLL parity.

In this case do the regular OLL parity alg like on a 4x4 (Rw U2 x Rw U2 . . .) Except instead of Rw do r (just the inner slice) and at the end tack on an extra U2 Rw' Lw.

I’ll have to practice that one... moving just the inner slice isn’t a natural move for me. But I’ll give it a shot. If it fixes the edge and prevents an OLL parity, it’s absolutey worth a day to drill it and get it down.

I execute r as 3r 2r' (actually 4r 3r' or 2l 3l' but that's because I mirror the 4x4 alg so I can do mostly right handed U2s). It does take some time to get down, but not too bad, and it beats doing 2 separate algs.

I first solved using Petrus in my 30s a little, but not too try and improve. But I never really got into it until I was 40. Like everyone else said you can get pretty fast with your method! If you look on cstimer there are different types of scrambles like only the last layer. You could use that to get more practice on just the end of your solve for example.

Down to 3:46 I feel incredibly slow though and doing it daily, maybe 10 practises a day or so.

I am definitely going to have to look at how I get the first white square and the small T’s because that alone takes me 1 minute!! There must be an algo for it.

There are many tips for each process. Cross is something you can improve with tips and many solves - not much of algorithms.

I think this is similar to this tip (at 1:49):

I was not found "inner slice" alg, but tried to "reconstruct" it . If I'm not wrong this is it:

x' 3R2 U2 x U2 3L U2 3R' U2 3R U2 x U2 3R U2 x2 3L' U2 3R2

Wow this is amazing that you were ‘me’ forty years ago. What an fascinating story.

Can’t wait to become a geezer myself


ow

Welcome, "40 Yearbie". You still have 40 more years of fun (at least) ahead of you. I am currently really enjoying all the nuances of F2L, and not worrying much about time.

x' 3R2 U2 x U2 3L U2 3R' U2 3R U2 x U2 3R U2 x2 3L' U2 3R2

That's just the "red bull" parity alg (r2 B2 U2 l etc.); most people use lucasparity these days. However, with the red bull alg, you can optimise the inner-slice version by doing the first and last moves as wide moves instead of inner-slice moves.

 

[newtonbase]

From your message I think you are saying you completed 15 solves!!

This is the multiple blindfold event. @Mike Hughey has memorised 15 cubes then attempted to solve them blindfolded. He got 14 of them correct. There's a few of us who do that event on here but not many who can attempt that number of cubes. (You get to choose how many to do).

Wow that gives me an insight how people become sub 10 second solvers. It’s way over my head and it seems there’s a big leap from solving verbatim vs solving using skilled moves shown in that YouTube video. When I complete my moves, for the most part at least, I have no clue what I am doing or why. I wonder if as I become more natural I will start to understand what each move is doing and then begin to apply more efficient moves. I think I have many months ahead of me, but I am determined and still do between 10 and 20 solves each day. I am even going as far as to buy a tiny cube so I can literally take a cube anywhere, solving on the loo even

Actually, on that, can you suggest a good quality smooth tiny cube? The best I can find is a MoYu keyring. The cube I have now is a MoYu Aelong and I am very happy with it at £10.

When you first pull up cstimer, click on the box where it says "WCA" and pick "3x3x3" from that menu. Then the box next to it will say "WCA". Click on that box and pick "last layer". Voila - scrambles that only scramble the last layer.

I just had a big near-total success for multi. For the "Nationals Simulation" thread, second attempt:
14/15, 57:41.98 (10:2E; memorization: 37:15.30)
I just had 2 edges wrong on the tenth cube - there were two flipped edges and I only saw one of them when memorizing.
I can really do 15!
Now to start trying to increase. 16 certainly looks doable, anyway.

Sorry to expose my dimness, if I follow this algo tonscambke just the last layer my entire cube is scrambled! If you have a second to knock me about the head, what am I doing wrong?

My guess is you're doing some of the moves in the wrong direction. Take care over primes. They are always anticlockwise.

@40yearstosolve / Key chain cubes are small and easy to carry but 1) really bad in turning and 2) pops up easily. There is a relatively small cube called Valk Mini. But, just regular cube is not that bad to carry. I always carry one cube with me so that I can play with it anywhere. I believe folks here all same.

 

[40yearstosolve]

I had ordered this one, it’s made by MaYu so in theory should be the better of a bad lot as it is a keyring. Will report back!

Sorry I meant to attach the photo. The algo should be to scramble just the top layer is my understanding. I start with a completed cube.

I get just the last layer scrambled with that scramble.

In cstimer you can go to the "Tools" and select "Draw Scramble", and it will show you what the scramble is supposed to look like on your cube once you apply it. If you don't get a scramble that matches the picture, then it means you've applied the scramble incorrectly somehow - as someone mentioned earlier, perhaps by performing a turn clockwise instead of counterclockwise or vice-versa?

Gawd I’ve got a lot to learn. Had my D and L wrong way around. I don’t use them in any current algos! Thank you and sorry
