Can anyone explain to me what it means when a cuboid is extended not fully functional? Does this just mean that the puzzle can't shape shift like a C4U 3x3x4? Sorry if this seems like a dumb question I'm still relatively new to Cuboid lingo.

Extended means that the puzzle is essentially a shape-mod of a simpler puzzle. For example, an extended 3x3x4 is just a 3x3x3, but it has extra pieces glued to one face to make it look like a 3x3x4. A fully functional 3x3x4 (like the c4u 3x3x4) would work like you would expect it to (and that means it actually wouldn't shapeshift).

If someone ever says cuboid it means a fully functional puzzle. It doesn't say anything about shape shifting yet though. A fully functional 3x3x4 doesn't change shape simply because a 90° of a 3x4 face obviously leads to a block of the mechanism. So cuboid can change shape but it depends on the dimensions.
There are also exceptions. For example there are 3x3x2 cuboids, I believe invented by smaz, which can change shape. I don't really know how. :lol:

The domino existed long before smaz's version I believe. I would also argue that if it can do that funny move you're talking about, that it is not a true cuboid.

Just to add to the confusion sometimes people make fully functional cuboids by extending other puzzles. For example, the common way to make a 3x3x5 is by extending a 3x3x3. In this case though the extensions are fully functional. Normally though as stated if a puzzle is labelled as 'extended' it does not have full functionality.
