Echoed Regions

(Published on 1. September 2020, 04:34 by Bismuth)

Normal sudoku rules apply. The clues outside the grid next to a row or column indicates the sum of the digits "sandwiched" between the 1 and the 9 in that row or column. There is exactly one digit repeated in the green/blue region. This digit is the only digit that does not appear in the blue/green region. For example, if there are multiple '1's in the green region, then there is no '1' in the blue region.
