Normal sudoku rules apply.
Entropy Columns: Every 3 consecutive cells along each column must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).
Region Sum Lines: Box borders divide each blue line into segments with the same sum. Different lines may have different sums.

This might be a one star if you are very comfortable with the global constraint. I hope you enjoy!

A bit confusing at very beginning. But when you have found the right place to start coloring, the rest is quite easy and enjoyable.

Loved it - I think 2* is fair. Underrated puzzle for sure :)
