Sandwich on a Saddle

(Eingestellt am 16. April 2024, 22:19 Uhr von Schma)

I tried to come up with a new ruleset that combines Thermometers. Have a look at my "Sandwich on a Saddle" Sudoku.

Any comments are highly appreciated. :)

Play on SudokuPad

The rules are as follows:

  • Sudoku: Normal Sudoku rules apply.
  • Saddle: Brown circles are saddle points and are always connected to 4 brown lines representing a saddle (or a hyperbolic paraboloid). Moving away from a circle, digits on a line have to either strictly increase or decrease in relation to the number in the circle. Each circle has two opposite lines with increasing property and two opposite lines with decreasing property. The orientation may be different for each circle.
  • Sandwich: Digits outside the grid show the sum of the digits between 1 and 9 in the corresponding row or column.
  • There are no negative constraints.

To further explain the saddle rule, it can be seen as combined thermometers. The saddle in Box 1 might look like one of the two examples shown below:

In terms of difficutly, I would rate the puzzle at 2/5. Although the Saddle rule is new, I tried to keep it simple.

Lösungscode: All digits from row 3 (left to right).
