Rules: Normal Sudoku / Normal Variant rules apply.

Normal: Place the digits 1 to 9 once each in every row, column, and 3x3 box.

Kropki Dots – Digits on black dots are a 2:1 ratio.

Region Sum Lines – Box borders divide blue lines into sections with equal sums. Blue lines and their section sums may be the same as or different from other blue lines and their section sums.

Renban Lines – Digits on purple lines are a set of non-repeating consecutive digits in any order.

ALL LINES are both Renban AND Region Sum lines.

Commentary Corner: Just having a little more fun exploring the effects of combining two variant rules into one. Enjoy!

Very tricky and fun solve! Really enjoyable! I will be interested to see how this ends up being rated. My guess is it will end up being 2*, but I would say on the higher side, maybe 2.5 or so. Either way, thanks so much for sharing with us!!
