or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode, a number entry mode for placing Tapa clues, and 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.)
Author/Opus: This is the 8th puzzle from guest contributor Carl Worth.
Rules: Standard Tapa rules, except that the digits have been encoded with a cipher into letters. Each letter represents a different positive integer, for the solver to determine.
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.
