Identical levels - different numbers of moves

How well spotted! Yes, I've had a few déjà vue experiences, but never could remember where I had seen a level before, so until this one I could not know for sure if the level was just similar to another I'd played or exactly the same. I scrolled back to add screenshots to your post @TPS23 . There is in fact a small difference, being the marmalade and empty squares on the starting boards, but apart from that definitely the same board. Also, I will add that I failed miserably to get anywhere near passing the 20 move version on my first try whereas I sailed through level 9177 on my first try with 11 (!) moves spare! There is in fact a huge difference in level difficulty here, and evidence that the level design team ran out of ideas at this point. (I had a timed colour bomb from daily treat machine)

I did some more detective work on this level and checked it out on YouTube. In fact these two levels have been like this since the videos posted three years ago. It may be that someone spotted they were completely identical three years ago, because looking at Johnny Crush's video level 9060 really WAS the same as level 9177 with no marmalade, but the Skillgaming video, also from 3 years ago, shows the present version with the marmalade. @Johnny_Crush is very knowledgeable on such double levels that are identical but I'm not sure he is still around.

Nice detective work @TPS23 ! I'll keep my eyes open for other levels like this.
