This puzzle combines arrows with a constraint called Watchtowers.
Ruleset:
- Normal sudoku rules apply.
- Numbers along an arrow must sum to the number shown in the attached circle.
- Each small 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 small squares must not be watchtowers and they must therefore see more or less than X cells.

Having solved the other three Watchtowers, this was probably the easiest one, so my suggestion is to start with this one if you are not yet familiar with the rules. Although placing the last digits took a while... :-)
Thx!
