If the first of these was challenging, this second of the four "pentoku" puzzles I created should engender some good will. It's one of the easiest puzzles I've created.
The official rules:
- The digits 1, 2, 3, 4, and 5 appear in the above puzzle.
- Each shaded region contains exactly one of each of the digits 1 through 5.
- No row or column can contain more than two appearances of any of the digits 1, 2, 3, 4, 5.
- Squares with multiple colors contain a number that’s used in both of the associated adjacent regions.
