I'm sure I did this one without using the wraparound. I just used the usual rows, columns and the closed regions; the rest took care of themselves!!!

I'm still not sure what you mean by "without using the wraparound". Those single squares (orange and blue) ar part of closed regions, but you say you use closed regions.
But to figure out those two squares you don't need to use closed regions, that's true.
A puzzle should be called "Wraparound" if you can not display it without at least one closed region being continued at the opposite end of the puzzle. If you shift this whole puzzle three squares to the left (it's the same as cutting the 3 left columns and paste them to the right of the other 3), then it's still the same puzzle, but the "wraparound"-cells would be pink and green.
Depending on how you shift the puzzle, each closed region could be a wrapped one... That's why I'd like to say that "without wraparound" for me is the same as "without closed regions"...
(I hope you get what I mean....)

JoergWausW I meant that I solved this as though it were an ordinary jigsaw, so I didn't need the regions which were not closed (which I call the wraparound element of the puzzle) I'm not into all this shifting, but what I am saying is that I treated this using only closed regions and didn't have to use the odd bits as they were the ends of lines or columns

@Elisabeth, thank you for clarifying :-)
I remembered you saying you were a bit familiar with math, so I thought you knew about transpositions (shifting).
In the end, Wraparound puzzles are the same type of puzzle as Jigsaw, but the closed regions can not fit into the 9x9 frame without wrapping. If you exclude some regions from being used during solving, it is basically the same as not using some closed regions in a Jigsaw puzzle. The additional diffilculty with Wraparound: you have to remember regarding those cells at the other end of the grid when making choices in those wrapped areas.
And we had "Wraparound" puzzles that could have been displayed as regular Jigsaws if they were just shifted by a couple rows or columns...

Of course I know, JoergWausW I am just past taking this all so seriously!!!
I still say I solved this puzzle as though it were just a jigsaw without having to use the fact that some of the regions were not closed.

Key
A yellow/light blue highlight in the time distribution charts highlights your time, where relevant.
Rating scores out of 10.0 show the average difficulty rating chosen by users, where 1.0 is "Easy" and 10.0 is "Hard".
If a puzzle is opened more than once, including by loading from a saved position, then this is potentially a significant aid so it is listed as being completed with 'multiple sessions' for the purpose of the best time/average rating displays above.
Minor aid is defined as no more than one use of 'Check solution' when incomplete and/or no more than one use of 'Check solution' when wrong; and/or using highlighting aids (show repeated digits, show broken inequalities and show valid/invalid placements [slitherlink] only). Major aid is any and all other use of the solving aids except for 'show wrong'.
