Normal sudoku rules apply. Every three-cell-segment of a teal modular line contains one digit from the groups {147}, {258} and {369}. The sum of the digits on a thin gray line equals the sum of the digits in the attached circles. Adjacent digits on a green line differ by at least 5. Purple lines contain a set of distinct consecutive digits in any order. Digits in cages do not repeat. Gray circles indicate odd and gray squares even digits. The digits on the MARKed diagonal sum to 60.
