Where 1 overlaps 2, 2 overlaps 3 etc...
this works surprisingly well! Thanks!

I tried to take a screenshot at the end of the shufle process, sometimes a bit hard to tell which one is top/bottom, but especially 1/2/3 are relativly easy to guess.

For anyone wondering, there is a typo in your matrix, it should be

6 3 1
8 5 2
9 7 4

...but if you got the idea, its obvious, but maybe someone was confused...

Thanks for the tip :-)
