Yes. But it is a prototype, and like all prototypes it takes a lot of work. (Since people are asking me "how much?", I sell it for $500, so they stop asking - I don't want to spend all my time making prototypes, while there is so much more work to be done PHYSICAL CUBE CHESS) Right now I am...

Rotosphere is different in one aspect than Rubik's cube: the pieces are interchangeable and they don’t require a specific orientation... this makes the solving aspect more flexible - multiple ways to create specific pattern. Too bad I had to let it go... no market for it it turned out. I may...

When I worked on it, it took me a month to create a star pattern...

I did not put it in an app store. However you can play it with Unity player on the rotosphere.org Since I did not get patent, I let the project die...

Wow! That is a perfec subject of discussion... Many people here already love cubes. Not just solving them—but learning a system, seeing patterns, and turning confusion into order. So maybe some of you would enjoy trying something new—especially those who also play chess. A few years ago I...

In the end I did not get the patent, so I did not see any point to invest in something that I won't be able to protect. Now I have another project. Cube this time. CubeChess that is. I wonder if those who know cube with their fingers can think around it as well :) https://cubechess.com/...

Regarding the mechanism -- The prototype I had sent you indeed was made several months ago. The new prototypes are much better but I don't have enough of them... My intention is to make the first release with magnets, so this early edition will be great for experimenting and learning. I...

My prototypes are made with 3d printer, not wood. Or are you referring to something else? As to solving -- sure. It is a lot of fun! Very nice twisting experience... I even enjoy getting lost every now and then.

Thanks, Filipe. I have a little doubt it will be a success! Even with the setback, good things are happening... Some big entities are starting to pay attention.

this is an example of how you can take two different paths to get to the same place in RotoSpheree... RotoSphere is like this!

I think I did approach Qiyi -- there was no answer... But that's OK. Betting on big companies is always asking for a mirracle -- too many people knock on their door all the time and the standard operating procedure is to reject. If, as an examiner of submissions you make a mistake rejecting...

Just an update after a few months of silence. My first preference, licensing path for making RotoSphere wildly available is still on the table, but I am also taking another path -- I started a company Brainy Toys, LLC with the intention of marketing and possibly manufacturing RotoSphere. There...

RotoSphere is pattern-based, so it has multiple "solved states" with "half and a half" being the easiest... (you just need to move the colors to separate hemispheres without the need for precise location for each tile). As you start the puzzle you pick the destination you want to go to --"half...

I don't have to have the patent approved for starting production and marketing (patents take 2+ years to be approved) -- The main delay is in manufacturing and getting into distribution... In my case since I am giving it a chance to try the licensing route before I commit to starting a company...

It is possible... However, solving RotoSphere is quite a different experience than cubes or even megamix -- you always rotate half of the puzzle -- not 1/3rd of a cube or 1/6th of the megamix. Honestly, I do not know how speed-solving would work with RotoSphere and if you even could use...

I've seen this concept when I did patent searches... It is among a few spherical concepts for twisty puzzles. I think is even possible to project a cube onto a sphere if roundness is the goal...

Here is the official RotoSphere "Hello World" video with an amazing original RotoSphere musical theme!
