The unshaded regions create a 10x10 grid scattered throughout the big grid. In this 10x10 grid, place the digits 0-9 exactly once in each row, column, and region.
Normal Japanese Sums rules apply. Colors used in this puzzle are orange (r), green (g), black (b), light blue (L), dark blue (k), yellow (y), and purple (p). For best results, remove all unshaded marking you have done once completed.
Japanese Sums rules: the squares outside the grid indicate the order of the runs of contiguous cells that must be shaded the color of the clue. The number in the square indicates the sum of the cells in the run. There must be at least one unshaded cell between runs of the same color, but that is not required for runs of different colors. All shaded runs are given.
Thank you to Maff for creating this very interesting grid!

Really, really fun. It's actually not that difficult, but you have to be really careful. Otherwise you can start all over again. I thoroughly enjoyed it. The puzzle, that is, not starting from scratch. :)

Beautiful! An absolute nightmare to scan especially as a colorblind person, but I'm very glad I stuck with it.

Such a unique concept. It takes some time to wrap your head around the rules, but it works wonderfully :)
