Whirlpool Sudoku

(Published on 17. July 2020, 10:11 by donut and chicken)

Rules:

Normal irregular sudoku rules apply. (Place every number from 1 to 9 in all rows, columns and 9-cell regions.)

In addition, normal killer sudoku rules apply. [The number in the corner of a cage is the sum of all the digits inside its cage, and digits cannot repeat within a cage.]

Finally, the "rings" in the grid [similar to killer cages but more rounded and does not have a number for a sum, and it always contain two digits] contain the only instances in the entire grid where two adjacent cells have consecutive digit values.

Enjoy!

The puzzle:

Alternative Name: The Roundabout Sudoku

Solution code: Column 8 (top to bottom), then Row 6 (left to right), no characters in between; Example: 12356789123654789

It was challening, but makeable in a sensable time.

I knew some strats when it comes to irregular sudokus that's why it has a 3/5 difficulty imho. (without them it could be noticeable harder)

Ty 4 creating&sharing. It was a lot of fun.
