Greenhill's 5 layer Square 1


Layers 2 and 4 operate, (independently), in exactly the same way as layers 1 and 5 (top and bottom layers of standard Square 1). It is slightly harder to instantly recognise the shape patterns that form in layers 2 and 4 as they are partly hidden by layers 1 and 5.
Having no 'top/bottom' colour, each of the edge pieces in layers 2 and 4 can be placed in one of two 'correct' locations, unlike in the top and bottom layers where they all have their unique position. This can lead to extra 'fun'.
When scrambled the extra layers create extra 'blocks' when a vertical turn is tried, again extra fun. It is extremely hard to do/follow.
Layers 2 and 4 could not be equal thickness to layers 1 and 5 (I did try) because the way the inner mechanism works, layers 1 and 5 pieces would drop off when one side was turned 90 degrees. I also think it looks better with layers 2 and 4 being thinner (11mm), the proportion of the whole puzzle is better.

Very nice!

Do you have any pictures of the internal mechanisme?

Absolutely amazing!

Did you use Square-1's pieces to make layers 2 and 4 or did you cast them?

wow, I would try to apply for a patent on the mechanism, or something to keep others from making the puzzle and selling it. Although I guess by posting here, you kind of have some proof of the existance of the puzzle

A very nice puzzle. I can see how this was accomplished although I'm wondering about what construction method was employed. Were existing layer pieces heavily modified or were the 2 and 4 layer pieces individually cast? My vote would be for cutting and modifying the 1 and 3 layers of a standard Square-1 and grafting on cut pieces of the middle layer into the now half size 1 and 3 layer pieces. It certainly does look seamless if this method was employed.

I believe everything has been said already, but indeed this is again a fantastic new puzzle.

As usual with Anthony's puzzles, it is of pure professional quality.

What I also like very much is that it appears that we are getting an entire new chain of puzzles here with the trademark "Greenhill's" (Greenhill's Dodecahedron, Greenhill's 1, Greenhill's 5 layer Square 1,.....).
I can't wait for the next issue to appear!!!

Two questions:
- would it be possible to make some of the layers thinner in order to make all sides of the "cube" of equal length?
- not understanding the internal mechanism yet, would it be possible (e.g. by reducing the thickness of some layers) to extend the principle into a (very first!!) 7-layer puzzle?

Congratulations!!!!!!!!!!!!

Geert.

Sandy,
I hope this beauty will find a place on your site.

Well I think its dumb. No Just Kidding. It's awsome. I'd actually like to see it in differents mixed states. Again, Awesome new 'cubicle'.

Awesome!!!

Now where's the 4-layer Square-1!?
I can see how this could be done, and would require rather large center layer slices.

I think sq-1 "wants" an odd number of layers, I can't see how to do even with out either bandaging some pieces in a slice or having a hidden centre layer that is turned by one of the visible centre layers.

I knida see what you mean. I was implying the hidden ring inside the puzzle but now see this would not work (like 2x2x2 with all pieces free). If some sort of small appendage extended from this hidden ring as a guideline, then an even-order Square-1 would be very possible.
