I made Half turn only cube easy variation from Takafumi's idea.
The name is "HANZOH" named by Mr.Suse, Takafumi's friend.
HAN means half by one character Kanji, and ZOH is used often for old person's name's tail.

This cube can be rotated only 180 degrees.
When rotate 90 degrees only, separate line is shifted, and lock not to rotate other axes.

He made normal 3x3x3 version's Half turn cube, but it looks similarly outward of normally 3x3x3 cube. ;)

Case's left space is for his normal Half turn cube.

I loved how this was discussed less than a year ago, and now it's real.


It looks amazing. I wish we could have a sneak peak at the inside.

Brilliant design Hidetoshi!
Cube "bumping" idea has more potential than I first thought!
Well done!

So does solving this make it more like a domino?

It is trivial to solve...

I love it Hidetoshi! And I think I prefer this design where the restriction is visible on the outside. Although for me personally it would look even better in the western white-opposite-yellow colour scheme. Blue and white on one face looks a bit too scrambled for me.

Excellent!

Thomas

Here's my method:

Solve the corners.
Solve the centers in relation to the corners.
Solve the edges with some basic algs.

If by any chance you run into a 'parity' of a 3 edge cycle.

R2 U2 F2 U2 R2 U2 F2.

Corners and centers are trivial, edges can all be solved with R2 U2 R2 U2 R2 U2.

I actually scramble and solve the cube like this sometimes. It makes for an interesting challenge, if not too difficult.

Excellent work once again!

Don't forget the parity.


Here's the non half turn way to get into it.

R2 E R2 E'.


See my previous post on how to cycle the three edges in the slice.

Can of course cut down with move cancelation. Efficient? No. Simple? I think so.

chris that is far too long. :P Try the commutator: X=(RU)x3 Y=BDB, of course, omitting all those "2"s.

I know it's long, I know it can be done better. I was just saying it was wrong to assert that you can't solve that case with only that alg.

Very cool. :) I like it a lot. (I really have to mod a Rubik's cube when I have
time.)
