Logic Masters Deutschland e.V.

This time lmdemasi kindly asked for more approachable Doppelgänger puzzles. Hope this one is up to the task.

• Doppelgänger Sudoku:
  • Fill each cell of the main 9x9 grid such that every row, column and 3x3 box contains a 0 and eight different digits from 1-9.
  • No two rows, no two columns and no two boxes may be missing the same digit.
  • For each 0 in the grid, the digits missing in its row, column and region must be three different digits.
• Adjacent digits along a green line must have a difference of at least 5.

Online in Sudokupad (and with extra note space).
