(Published on 26. November 2021, 16:01 by Aspartagcus)
Another doppelgänger. :)
This puzzle can be solved either as a creek puzzle, or an irregular quadruples sudoku.
Irregular quadruples sudoku rules:
- Standard irregular 5x5 sudoku rules apply, using the digits 0-4.
- The digit in a circle has to appear at least once in the cells it touches.
Creek rules:
Shade some cells such that the number in a circle equals the amount of shaded cells it touches, and all the unshaded cells form a single orthogonally connected region. (The borders for the sudoku regions can be ignored.)
