I got the Fisher cube from Puzzle Master as part of my recent large order - they have a huge selection of Meffert's and other manufacturers' Twisty puzzles at decent prices (if you prefer it in black then Puzzle Master have it in that colour too). This can also be bought from all the usual specialist twisty outlets. It follows the standard Rubik's cube puzzle colouring and is a 5.7 cm cube also like the standard cube. Puzzle Master rate it as a level 9 in difficulty and this is correct if you are not a twisty person but if you can solve a regular cube then it is not so hard (apart from the alleged "parity of false equivocation")!
So, if you can do a 3x3 cube should you get one of these? Absolutely yes! This uses the same basic techniques but adds some very interesting twists to them, making it a rather interesting and really fun puzzle to solve without being ridiculously tough.
As you can see from the pictures, it is just a 3x3 cube with top middle and bottom layers as normal but the vertical cuts in the cube have been rotated by 45º. The faces, therefore do not turn at all - it is an edge turner in the vertical orientation. This makes for a very attractive cube but it also means that when it turns, odd things happen - it very rapidly starts to change shape until after a full scramble it becomes a very shape-shifted nightmare:
|Doesn't look too cube-like anymore!|
Not so fast Batman!!! There are 2 approaches you can take! The first approach should be solving it as a normal cube with a flat first face - easy peasy. BUT you could make it interesting by solving a non-flat face first - just for the extra challenge:
When solving with the alternative start, an even more interesting parity seems to occur - the edges are orientated correctly but they are permuted incorrectly:
Now all of you are aware that I have become a complete twisty puzzle freak - I have 64 of the damn things in my study just now with a list of more to buy (just so I can annoy the present Mrs S even more)! I would say that ALL puzzlers should at least own and be able to solve a standard Rubik's cube - it is one of those "basic collection" puzzles. If you get into them then there are lots more to try.
I would suggest that the Fisher cube is another one that is worth owning early on in anyones collection because of the several extra interesting problems that it poses without being too horrific. So, all of you puzzlers out there - go and get one of these! It is great fun!
