Theme: No Zeroes
Author/Opus: This is the 132nd puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Variation of Sudoku. Instead of the digits 1 through 9, this puzzle uses the digits 1 through 7 as well as two black squares in each row, column, and bold region. Clues outside the grid indicate the sum of all digits between the black squares in that row/column.
Answer String: Enter the 2nd row from left to right, followed by a comma, followed by the 8th row from left to right. Use a capital X for all black squares.
Time Standards (highlight to view): Grandmaster = 8:30, Master = 10:30, Expert = 21:00
