Rules:

Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box.

Ratio pairs: Cells separated by a black dot are in a 1:2 ratio. Not all dots are necessarily given.

Sandwich sum: Clues outside the grid indicate the sum of the digits between 1 and 9 in that row or column.
