Hi Twisty Puzzles fans,

Treasure Skewb is a Skewb variation of Oskar's Treasure Chest. When the puzzle is solved, the puzzle can be opened in two halves. At the inside is a cavity, where one can hide valuable items.

Watch the YouTube video.
Buy the puzzle at my Shapeways Shop.
Read more at the Shapeways Forum.
Check out the photos below.

Enjoy!

Oskar

Very cool that this also works with a skewb shape!

I love the Treasure Chest, but it always kinda bugged me that only two thirds have to be solved to open it. If I'm thinking about this correctly, the Treasure Skewb actually has to be completely solved to get at what's inside, right?

I don't think so. There are two corners that are not adjacent to the opening cut. I think these two could be swapped or rotated and it would still open. Though I do notice that all the face centers have to be super solved unlike a normal Skewb. Is there a parity factor that would come into play that would force these 2 corners to be solved in order to get the rest of the puzzle super solved?

Two opposite corners cannot be swapped. On the original Skewb, one of those two corners would be on a spider axis, while the other would be a free moving piece.
Furthermore, it is not possible to twist either of those corners without twisting some of the ones around the equator, so the treasure chest skewb can indeed only be opened if it is fully solved.
I think that the square pieces could be designed so that their orientation does not matter.

This is cool, though I have a question: Could the core of this puzzle be sized such that it could replace the core of all the Skewb shape mods Meffert's has produced? A Treasure Chest Golden Cube or a Treasure Chest Fisher Egg(Easter Egg Puzzle) would be cool, especially if I could simply disassemble one from my own collection and combines its outer pieces with the treasur skewb core.

This is so cool! I want one...

It should be only slightly harder to solve because you'll need an algorithm for twisting centers. Should solve exactly like Tony Fisher's Skewb Xtreme.

Several of my YouTube fans thought that publication of the Treasure Skewb on April 20th (420) was a hint what treasure to hide inside the puzzle. :-)

A nice minimal way to sticker this would be to only sticker the parts of each face where the special cut lies. For example, splitting a circular sticker halfway over the cut on each face, so half is on a corner and half is on the face center.

... Or take off all the stickers completely!

The only reason to have stickers is to know when the puzzle is solved, but in this case the thing opens up when it is solved, so you don't need stickers. :wink:

Perhaps a small modification can be made so that the thing clicks when you turn it, and the frequency of clicks corresponds to how almost-solved it is. So solving it would be like picking a combination lock.
