• Place the digits 1-9 in every row and column.
• The grid is covered in fog. Placing correct digits reveals more of the grid.

• Standard XV and Kropki pairs rules: Digits separated by a V sum to 5. Digits separated by a X sum to 10. Digits separated by a white dot are consecutive. Digits separated by a black dot are in a 1:2 ratio. Not all dots, Xs, and Vs are necessarily given.
