Watch my Sandwich
(Published on 7. March 2022, 18:22 by Angelo)
My very first puzzle combines sandwiches with a new constraint I like to call Watchtowers.
Ruleset:
- Normal sudoku rules apply.
- Clues outside the grid give the sum of the values between 1 and 9 in the row/column.
- Each circle represents a watchtower of height X, where X is the digit placed in that circle. Each watchtower must see exactly X cells (including itself) in its row and column combined. Watchtowers cannot see digits larger than their own height, nor past them. (e.g. A watchtower of height 5 would see a 3 behind a 4, but not behind a 6).
- Not all watchtowers are given, but cells with squares must not be watchtowers and they must therefore see more or less than X cells.

The puzzle is also available online via F-Puzzles and CTC-App. Have fun solving!
See the example puzzle below:
Solution code: Row 1 + Row 2, read from left to right, without spaces (18 digits)

I liked the puzzle a lot. But it took quite some time to get used to the rules. Nice variant, though!

Hi Bigger, it counts itself only once. I will add an example picture

can you please use an example picture? there's a lot ambiguity in the rules. for instance, the watchtower must see x cells including itself, so how many times should it count itself? should it be always 4 times as in 4 direction or only 1 time or 2 to 4 times?
