These diamonds are nifty, I can’t believe I waited so long to revisit them! What I find fascinating about them is that as much asthe first digit in a row or column affects the cells separated by diamonds, cells separated by diamonds affect the first digit in the row or column. At least sometimes.
Rules:
Normal Sudoku rules apply.
XY-Difference Pairs: Two digits in a row separated by a diamond differ by the digit in the first column of that row. Two digits in a column separated by a diamond differ by the digit in the first row of that column. Not all possible diamonds are given.
Digits in cells marked with an orange circle are odd.
Digits in cells marked with a green square are even.
Estimated difficulty: 1.5 out of 5
