Normal sudoku rules apply. Digits along a pink “renban” form a set of non-repeating, consecutive digits in any order. Digits do not repeat along gold “nabner” lines. Additionally, no two digits appearing anywhere on a nabner line can be consecutive. Eg If a line contains a 2, there cannot be a 1 or 3 anywhere along the line. Adjacent digits along a green line must differ in value by at least 5. Box borders divide the blue line into segments with the same sum.
