I have finished this series.
And have a lot of stickers left over.
There are 22 possible variants to make up variants like this.
One is missing here: the hexagonal prism which is octagonalEdges-variant too.
I consider the other 12 variants as repetitive and have therefore ignored them.

does all this puzzles are fully functional ? or just looks like big puzzles and act like 3x3x3 ?

Agreed. Those two puzzles on the left look huge!

come on! look at the title

They are JUST heavily disguised 3x3x3s. Like the mastermorphix in the picture.
And they are indeed very huge. Even worse: They have pyramidal shapes and therefore a nightmare to store.

belive me that if I asked, I didnt understand it completely...

just dont get angry, lol

Sorry! i didnt mean it in a harsh way!

But if they were fully functional. I bet he had put that in the title
