Circle sums are on the up, it seems. Diamond differences… not so much.
Solve this puzzle in SudokuPad.
Sudoku: Standard rules apply (place the digits 1 to 9 in every row, column, and 3x3 box; there are even some given digits here!)
Diamond difference lines (thinner, blue lines): The two digits adjacent to a diamond on a line have an absolute difference equal to the digit in the diamond.
Circle sum lines (thicker, pink lines): The two digits adjacent to a circle on a line have a sum equal to the digit in the circle.
