Theme: Clue Symmetry and Logic

Author/Opus: This is the 16th puzzle from our newest contributing puzzlemaster Carl Worth.

Rules: (Hybrid of Fillomino and Snake Puzzles.) Divide the grid along the boundary lines so that every cell belongs to a snake. A snake is a one-cell-wide path at least two cells long that does not touch itself, not even diagonally. Circled cells must be at one of the ends of a snake. A snake may contain one circled cell, two circled cells, or no circled cells at all. Numbered cells must be part of a snake with a length of exactly that number of cells. A snake may contain one number, multiple identical numbers, or no numbers at all. Two snakes of the same length cannot touch each other horizontally or vertically.

Also see this example:

Answer String: For each cell in the marked rows/columns, enter the length of the snake it belongs to. Enter just the last digit for any two-digit number. This example has the key “35522,44462”.

Time Standards (highlight to view): Grandmaster = 10:15, Master = 14:30, Expert = 29:00

Theme: Game of Letters (for Daniel Cohen)

Author/Opus: This is the 142nd puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place the 18 names into the grid, one letter per cell, so they can be read from left to right or from top to bottom, without crossing or overlapping each other. Treat the first and last names as separate entries. A dot between two cells indicates that both cells must contain the same letter. All possible dots are given.

Answer String: For each row from top to bottom, enter the number of unused cells in that row.

Theme: Octets (for Randy Rogers)

Author/Opus: This is the 226th puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Standard Kakuro rules. Also, digits do not repeat within the red bold regions. (The shading is used to help distinguish the regions as well.)

Answer String: Enter the values in each cell in the 2nd row from left to right and then in the 9th column from top to bottom, separating the two entries with a comma. Ignore black cells.

Theme: Clue Symmetry and Logic (for Veep)

Author/Opus: This is the 141st puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Variation of Slitherlink rules. The loop may now intersect itself at a point (it still may not coincide anywhere). At any dot at which more than 2 segments meet, the segments must all travel straight through the dot. This example may help:

Answer String: For each marked row, enter the length in cells of each connected group inside the loop from left to right. Separate each row’s entry with a comma. Shading the loop so that each fence separates a shaded/unshaded cell can help identify what is inside. For the example, the answer would be “11,12”.

Theme: Egocentric (for Chris Green)

Author/Opus: This is the 54th puzzle from our contributing puzzlemaster Murat Can Tonta.

Rules: Standard Tapa rules. Also, if two cells are separated by a thick border, this means that exactly one of those cells is shaded and the other is unshaded.

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 Obvious Lies (for Jamie Hargrove)

Author/Opus: This is the 53rd puzzle from our contributing puzzlemaster Murat Can Tonta.

Rules: Shade some cells black so that all unshaded number and arrow clues indicate the exact count of shaded cells in the given direction. Shaded cells cannot share an edge, and all white cells must remain connected as part of a single contiguous group. It is allowed to shade over some of the numbered cells; a shaded over clue may or may not be true.

Also, see this example:

Answer String: For each row from top to bottom, enter the number of shaded cells as a single string. For the example, the answer is “20212”.

Theme: Almost Antisymmetric

Author/Opus: This is the 143rd puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Standard Fillomino rules. Also, if there is a white dot between two adjacent cells, then those cells must contain numbers that differ by one. If there is a black dot between two adjacent cells, then one of the numbers must be twice the other. Either a white or black dot can separate 1 and 2. All possible dots are given (i.e., no unmarked borders can have numbers that differ by 1 or have a quotient of 2).

Answer String: For each cell in the marked rows/columns, enter the area of the polyomino it belongs to. Enter just the last digit for any two-digit number. Start with the 2nd row, followed by a comma, followed by the 8th row.

Time Standards (highlight to view): Grandmaster = 8:45, Master = 13:30, Expert = 27:00

Solution: PDF; a solution video is available here.
