Lucky 7
- Kropki dots
- Arrows
The brief
Normal 9x9 sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Digits on an arrowed line sum to the digit in the connected circle. If a circle has 2 arrows, both arrows sum to the circle individually. Cells separated a black dot has a 1:2 ratio (one digit is double the other). Cells separated by a white dot are consecutive. Not all dots are necessarily given.
