super puzzle, i've tried at least 3 time, 1 time I made an error I don't now where, and 2 time, I did not finish it because I was stuck, maybe I've made false assumption about the rule, but anyway very nice ( and I will finish it soon!)

Original 3x3 Block，eg. from R1C1 to R1C3 and from R1C1 to R3C1.

When you say 3x3 block do you mean 9 original blocks that are in sudoku or every 3x3 block there is e.g. from R2C2 to R4C4?
