Normal sudoku rules, renban rules, and 159 rules apply.

159 : The cells in column 1 tell you what column 1 is in in each row. So if r6c1 is a 7, that tells you that r6c7 is a 1. The same is true of column 5 and the digit 5, and column 9 and the digit 9.

Renban: Purple lines must contain distinct digits that form a single run of consecutive digits, however those digits can appear in any order. For example, 4657 is a vaild fill for a length 4 renban line.
