Rotosphere Prototype Review
Hey everyone! I got the awesome opportunity to try out a prototype Rotosphere. Thanks @Pawel! Here are my impressions. I will also make a video on it.
Turning
To be honest, this puzzle doesn't turn very well. But keep in mind that it is a 3d printed prototype in the very early stages. I was even told beforehand that the one I was being sent would be an earlier version, which I am ok with. The turning certainly isn't great, but it isn't unbearable. Nothing that kept me from not enjoying the experience.
Mechanism
The mechanism and pieces on this cube are pretty unique. The pieces have magnets on the feet to connect to a large round metal core. Definitely a makeshift way of holding the cube together, but it works. One thing I do really like about this is that it allows for solvers to easily take pieces on and off and rearrange them. Obviously this could be use to "cheat", but it could also be used to experiment and find new patterns and "solved states" (something I'll talk about in a bit). AFAIK though, this design is being phased out in the later prototypes for something more reliable.
Solving Experience
This is an awesome puzzle to solve! It is mostly intuitive, but surprisingly challenging. It stumped me quite a bit when I first got it! The methods and strategies I used were pretty different than most cubes. But at the same time, it will feel very familiar for cubers. Knowing common cube triggers and algs like the sledgehammer and sune can be very helpful later in the solve.
Multiple Solved States
This is the Rotosphere's main "gimmick" and the main way it is different than other twisty puzzles. This puzzle is absolutely OVERFLOWING with different patterns and states that could be considered solved. I haven't taken the time to explore many of them, but the variations I have tried have made the solving experience feel more fresh and challenging. For those who just want to do a basic solve though, the "half and half" pattern is what I started with as it is the easiest and makes the puzzle look the most "solved". The more complicated patterns all build on the half and half.
Conclusion
Overall I think the Rotosphere has a very bright future. The puzzle experience is some of the best I've had in a while. If the design and turning is improved, and
@Pawel is able to get these mass produced, then we've got the next great non-WCA cube on our hands!
