or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode, the composite Yajilin mode where left click marks cells, right click marks dots in cells or X’s on edges, left click+drag draws lines, and a number entry mode for the answer check.)
Theme: Nine Clues
Author/Opus: This is the 157th puzzle from our contributing puzzlemaster Prasanna Seshadri.
Rules: Variation of Tapa. There are two grids to solve simultaneously; each number clue must have a different arrangement of shaded cells in its eight neighboring cells from its counterpart clue in the other grid.
Answer String: Enter the length in cells of each of the shaded segments from left to right for the marked rows, starting at the top. Separate each row’s entry from the next with a comma. For entry purposes, the “A/B/C” grid is the grid with the longer entry for its first row. (The “D/E/F” grid has the shorter entry for its first row.)
Time Standards (highlight to view): Grandmaster = 6:00, Master = 7:30, Expert = 15:00
