Theme: All Clues are Different Clues (for Randy Rogers)

Author/Opus: This is the 162nd puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place the digits 1-7 (1-9 for the example) in some of the cells, so that no digit is repeated in any row or column. Numbers on the outside of the grid indicate the sums of adjacent digit groups in that row or column, in order. Each sum is separated by at least one unused cell. A ? can represent any sum 1 or larger.

Tapa (Total False) by Serkan Yürekli

Tapa by Murat Can Tonta

PDF

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.

Time Standards (highlight to view): Grandmaster = 2:30, Master = 5:00, Expert = 10:00

Theme: Clue Symmetry & Logic (for TheSubro)

Author/Opus: This is the 239th puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Draw a single non-intersecting loop in the grid that enters and exits each bold region exactly once. If a number clue is given in a region, that number indicates the exact number of cells used by the loop in the region. Unused cells cannot be orthogonally adjacent across different regions.

Answer String: Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. If the loop only has vertical segments in the marked row, enter 0. Separate each row’s entry with a comma.

Time Standards (highlight to view): Grandmaster = 1:45, Master = 2:45, Expert = 5:30
