No, I'm still trying to work one out :)

I figured if the smallest to largest wasn't going to work, it would likely be due to combinations of numbers where the smaller numbers add up to 10, but using larger numbers add up to 9.

A little trial and error found it.


I'm kinda thinking about something along the lines of "Use all the 1s to add up to 10, use all the 2s to add up 9, use all the 3s to add up 8, etc.", but I haven't been able to determine whether that is always going to work or not.
