Dutch Flat Mates: Double Arrows
(Published on 4. December 2024, 11:30 by damo_89)
I am once again honoured to bring this week's Dutch Flat Mate puzzle on behalf of Flinty. This week we are going Double Dutch with Double Arrows. Good luck!
- Normal Sudoku rules apply: Place the digits 1 to 9 once each in every row, column and 3x3 box.
- Dutch Flatmates: Every 5 in the grid must have a 1 directly above it or a 9 directly below it. It may have both, but it doesn't need both.
- Double Arrows: Digits along a grey line sum to the same value as the sum of the digits in the attached circles.
Hint
There are a lot of flat mate deductions in this. If stuck, think about where 5s have to go in a row or a column
