Difference Sudoku
(Eingestellt am 15. Juni 2020, 18:42 Uhr von mandourin)
Usual Sudoku rules apply : each row, column and 3x3 box contains all digits from 1 to 9.
Each circled digit between two cells is the difference between the corresponding digits.
I guarantee that this puzzle has a logical solution but it can be tricky to spot.
Lösungscode: Row 6, column 4.
