Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.

Purple lines: A purple line of length up to, and including, 5 is a renban. The digits along the line must be a non-repeating set of consecutive digits in any order. A longer purple line is a run-on renban; every group of 5 sequential cells along the line is a 5 cell renban. That is, it forms a set of overlapping renbans.

Cage: digits in a cage must sum to the value in the corner of the cage.
