Theme: Clue Symmetry and Logic (for Jamie Hargrove)

Author/Opus: This is the 161st puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Variation of Tapa Rules. Every given clue is lying in two ways: first, the number of given clues in that cell is false; second, the value of any given clues is not true for any part of the Tapa around that cell. For example, a 3 clue could actually indicate 24, but it could not indicate 2 (same number of clues) or 23 (the digit 3 appears). 0 is not a valid clue for this Tapa.

Total False Tapa Example

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.

Theme: No 2×2 White Blocks

Author/Opus: This is the 5th puzzle from guest contributor Jamie Hargrove.

Answer String: For each row from top to bottom, enter the number of shaded cells as a single string.
