3 Linked Sudokus

(Published on 12. May 2019, 17:24 by JonaS2010)

Continuing the tradition of the previous two years, here is a puzzle inspired by the German Sudoku Championship:

Rules: Solve all three Sudoku puzzles (rules see below). The central 3x3 region has to be the same in all three puzzles. (Other digits may differ. Each sudoku has multiple solutions, but there is only one valid solution with the same center box). An additional empty 3x3 box is provided for solving convenience.

Top left: Diagonal Sudoku. The two marked diagonals also contain the digits from 1-9 exactly once each. Top right: Frame Sudoku. The clues indicate the sum of the first three digits from the edge in the direction of the clue. Bottom left: Thermo-Sudoku. Numbers in the thermometer shapes must be strictly increasing from the bulb to the flat end(s).

Solution code: Diagonal: Column 7. Frame: Row 2. Thermo: Column 2

Respekt, Herr Autor! Minimalistische Vorgaben bei diesem Schwierigkeitsgrad und die dann auch noch symmetrisch... Großer Rätselspaß für mich.
