This puzzle is part of the Monthly Topic Challenge #13: Variety Slitherlinks.
I find something strangely satisfying about a well designed slitherlink puzzle, even one which is oddly coloured and plays with the rules a bit.
So I thought it was about time I tried creating one myself. The first version was a bit hard, so I added plenty of extra digits to make it a bit fairer.
Should be solvable by hand with no guessing/backtracking.
