Cubing challenge: peel the stickers off

[bcube]

Main thread.

By a process of gradual elimination, solve the following cube. New scramble is generated with each page refresh. You can make it easier by adding stickers (for instance if you are like me and don´t remember color scheme by heart ), however, this version of puzzle is already sufficient to be solved by a process of gradual elimination.

It was hard but I think solved it. Any other way to share this(rather than screenshot)? Maybe I also need to make this type of cube but a little easier.

 

[bcube]

Although this one has 1 more sticker than the previous one, it felt much harder for me. Oh, and of course I figured out the last edge piece color at the very end of the solve, realizing I need to swap several pieces. Resolving it was quite a challenge!



Edit: this sticker variation is actually quite theory-heavy. Never thought I would need to analyze a 6-cycle until now.

What do you mean by that? If you want to show others that you solved it, you can use the simulator to make a reconstruction of your solve.

Now go ahead and find the other solution

Edit: just to be clear, I meant the other solution on the first cube

Yes, I wanted to share that I solved it with solving time but I couldn't do it. So I shared only screenshot. Nice to know you can make a reconstruction.

I found a solution and think that's ok, don't want to 100% it

Cool, let us see

In case you didn't know and are interested: if you want to share the simulator inside the forum, this post might get you started. If you want to share the simulator outside the forum, you might use this tool e.g. in conjunction with this tool.

If you don't know the scrambling sequence and how the solved state looks like (as is the case for the second cube above for example), start by stickering individual stickers to match the scrambled cube above. Then you can add solving sequence and make the simulator to your preferred liking.

I've made it finally!
It took me about 5 hours to solve it.
After I took the following strategies today, I solved it in 1 hour.

1. Yellow Cross in stead of White Cross
This is because there are 8 yellow stickers which are more than White ones.

2. ZZ in stead of CFOP
This is because I can concentrate on the position of the edges, instead of their position & direction.

Sorry, but I couldn’t reproduce by the AnimCube with the following Code, the picture of the cube in my previous post.

<script src="AnimCube3.js"></script>

<div style="width:200px;height:200px;">
<script>
AnimCube3("facelets=*w***w*w*yyyyyyy*y1111**11**0***0*00*g**gg*g*bb*b*bb*b")
</script>
</div>

Great. Even though you solved it, remember that these cubes can be solved purely by the process of gradual elimination rather than using a trial-error method (but even if I use gradual elimination, it is still taking me a lot of time to find the solution ).

If you want to use CFOP/ZZ as your solving strategy, maybe this example will be even harder than the previous one for you even if it has less peeled stickers:

You don´t need <script src="AnimCube3.js"></script> unless you want to use the simulator on your own web-pages. All you need inside or outside this forum is setting parameters to their values. In your example it would be the following string: facelets=*w***w*w*yyyyyyy*y1111**11**0***0*00*g**gg*g*bb*b*bb*b

Duly noted
I will try that, too.

 

[Tito_H]

Test.


I’ve got it. I could generate the cube, using only the parameter 'facelets'.
Thanks.

I made it for less than 1 hour this time, thinking much the process of gradual elimination

 

[bcube]

Test.

Just letting you know, I added "To check that the simulator works as you intended, click on the Preview button before sending your forum post." to this post.

Nice. What solving strategy did you use?

Oh, I've just noticed that there is a Preview button. That's good!

Nice. What solving strategy did you use?

I used White Cross, since there are 6 white stickers + 1 Red-Green CP (=White sticker), which is more than Yellow stickers. Cross with other colors might be an option, but I am not color neutral.

6 corners out of 8 have 2 faces with proper colors whose color of the remaining face is obvious, so I could reduce the case in only 2 options.

I also applied EO, changing bad edges to good ones after finishing F2L (Anti Sledgehammer + re-Slot in the pair). In my case, I could solve with OLL T set, and PLL Y perm.

 

[Tito_H]

I didn't notice when I was solving, but I've just found out that the Blue-Gray-Gray CP can not be anything but Blue-Orange-White, because it would be duplicated with other CPs if not.

Good observation!

For the second and third cube I was able to figure out their gradual elimination process (my speedcubing method is Corners-first which helps in this case) with one difference being that I did the last step in 2 substeps because it is too difficult for me to trace 6 pieces at once.

For the first cube I was able to figure out its both solved states because I don't remember color scheme by heart. I used edges-first solving strategy there (thus swapping green-blank edges if encoutering corner parity).

 

[Tito_H]

I will try the first cube, although jamol have already given the solution.

 

[Tito_H]

This is the first cube.
I've made it in +/-30 minutes without so much hustle.
All 9 pieces of White Cross are obvious.
All Blue EPs are obvious.
Green-Gray-Gray CP should be Green-Red-Yellow because there is Green-Orange-Gray(=Yellow).
Orange-Gray-Gray CP should be Orange-Blue-Yellow because there are 3 other Orange-sticker CPs.
So, I now know what all 8 corners are.
Then, OLL and PLL solved the cube.

Using the Gradient Cube concept, I get a 3x3 with 20 stickers as the minimum. Can this be reduced any further? There are multiple solutions unless following the rule that the solution must be the original known scheme. This one is optimized for minimizing the number of different colors on each face, to improve recognition. Other configurations are possible in order to cater to anything else wanted. I like this minimum sticker concept since it fits perfectly with Straughan recognition and the Gradient Cube concepts that I've worked on.
