RULES:

Normal sudoku rules apply.

Region Sum Lines: Region borders divide thin blue lines into segments. The digits on each segment of a line sum to the same value. Different lines may have different sums.

Renban: Digits along a thick purple renban line form a set of consecutive, nonrepeating digits in any order.

Partial Kropki: Digits separated by a white kropki dot are consecutive. Not all possible kropki dots are given.
