I have prepared a set of 10 puzzles following the common theme of "Uncertainty". I am releasing the puzzles here on a daily basis, but if you are impatient, the full set can be found at this link. Each puzzle is a combination of two variants, but it is unknown in which parts of the grid each variant applies - that is to be determined during solving.
General Rules: Place a digit from 1-9 into each cell of the grid so that every row, column and outlined 3x3 region contains each digit exactly once.
Renban: Shaded regions must contain a set of distinct, consecutive digits.
Anti-Renban: Shaded regions must contain a set of distinct digits, no two of which are consecutive.
Combination Rule: In this puzzle, each shaded region follows either Renban Sudoku rules, or Anti-Renban Sudoku rules, or both.
Lösungscode: Row 5, followed by Row 7
