What's A Few Arrows Between Friends
- Arrows
- Between lines
The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9. Arrows: digits on a thin grey line must sum to the value in the attached circle Between lines: digits on a thick grey line must have values strictly between the values in the circles at the ends of the line. Lines do not pass through circles.
