Hi all puzzlefriends,
since I began working out with twistypuzzles I have had particular appreciation for the cuboids....I like cuboids very much, and now I'm asking me what of all cuboids is the most difficult to solve, maybe the 4x4x6, or the 3x4x5 shapeshifter....actually I think that those are very challenging, but I'm just curious about the other members of this forum with cuboids....so please let me know anything about your experience with that puzzles..... 8-) Thanks all for your posts.....
Happy puzzling to all!!

the only cuboid I own is a calvins 4x4x6, which I found was a bit easy,

I own a witeden 3x3x9 (i don't think that counts as a cuboid does it? as it has equal length sides?) but the algorithms I Learnt from that i was able to implement into the 4x4x6 the way I sequenced it in me head was.

1.solve like a 4x4x4
2.solve like a 3x3x3
3.solve like a 3x3x9
4.solve like a 3x3x3


...5.solve it like a MOTHERFLIPPER!..

While probably not the most difficult cuboid, the 3x5x7 can be quite difficult. Absolutely love solving it.

No cuboids are particularly difficult to solve once you understand their structure and where they come in the cuboid classification. This classification was discussed by SuperAntonioVivaldi on his YouTube Channel, here is the first in his series.

I also discussed this very thing with his permission on my blog:
http://www.puzzlemad.co.uk/2013/01/first-there-was-cube-and-then.html

The hardest cuboids really are those that would have the most phases to their solution strategy and the potential for the most parity problems. In general the "most difficult cuboid" would therefore be one of the "Ultimate shape-shifters" group - that is it takes the form:
N x (N + E1) x (N + E2) where E1 & E2 are 2 different even numbers.

Until Calvin decides to mass produce the 2x4x6 designed and first made by Hunter these can only be found as bespoke mods or as Shapeways prints! :cry:

The first to be produced in this group was Puzzle Maestro's 3x5x7. I have it and it is magnificent!

Image

Obviously bigger becomes more arduous (although not really more difficult) and there have been fantastic strides recently in these puzzles.

Traiphum made the 5x7x9 (using CrazyBadCuber's design - thanks Dan) and it is fantastic too.

Image

BUT to add to the difficulty you need to add something new - making an even order version will add the even order parity to the puzzle and Jeremy Eisenberg (Jerm on TP) has designed 2 amazing versions of which I only have the smallest (So far :lol: :lol: :lol: ). These are the 4x6x8 and 6x8x10!!!! :shock:

Image

So if you really want the "Ultimate" most difficult cuboid then I would buy the 6x8x10 from Jerm's shop here Or for a little less money then get the 4x6x8 here
