Above 20 Sudoku
Inspiration for this type comes from Luo Si Yuan.
Solve online in Penpa+ (thx Henrypijames!) or F-Puzzles (thx MrBeachHut!)
Apply classic sudoku rules.
Each 3x3 block contains a row and a column of which the sum of the three digits is 20 or more.
Solution code: Row 7, followed by column 3.

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?
