The brief
Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. Consecutive pairs: Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given. RUSSIAN DOLL SUMS: In each row or column with an outside clue, there exist two digits A and B which sum to the clue and the digits between A and B also sum to the outside clue. Multiple clues in the same row or column are separated by spaces.
