Theme: Symmetry and Logic (Note: this puzzle originally appeared in this year’s Japan dakejanai Zukei dakejanai Puzzle Championship.)

Author/Opus: This is the 42nd puzzle from our contributing puzzlemaster Serkan Yürekli.

Rules: Place either 0, 1, or 2 mines into each empty cell so that each number represents the total count of mines in all neighboring cells, including diagonally adjacent cells. See also this example:

Answer String: For each cell in the marked rows, enter the number of mines (0, 1, 2) for each cell. Enter 0 if the cell is a number cell. Separate each row’s entry from the next with a comma. In this example, the answer is “022102,002000”.

Time Standards (highlight to view): Grandmaster = 1:15, Master = 1:45, Expert = 3:30

Theme: Hourglass

Author/Opus: This is the 103rd puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Standard TomTom rules, using the integers 1-6.

Answer String: Enter the 1st row from left to right, followed by a comma, followed by the 6th row from left to right.

Time Standards (highlight to view): Grandmaster = 1:30, Master = 2:15, Expert = 4:30

Theme: Symmetrical Clues (allowing for rotations and reflections)

Author/Opus: This is the 102nd puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Standard Slitherlink rules. Also, there are some sheep (marked by a reflected 2 in blue) that must be inside the loop and some wolves (marked by a rotated 3 in red) that must be outside the loop.

(Note: the reflected/rotated digits in blue and red do not actually serve as loop clues meaning 2 and 3, just as sheep and wolves. We chose this presentation because the theme works better with the wackiness of some 2’s and 3’s even if it needs this extra note.)

Answer String: Enter the length in cells of each of the internal loop segments following the arrows for the marked rows, starting at the top. Separate each row’s entry with a comma.

Time Standards (highlight to view): Grandmaster = 1:30, Master = 2:30, Expert = 5:00

Theme: Equal Distribution and Symmetry of Clue Numbers

Author/Opus: This is the 6th puzzle from guest contributor Roland Voigt.

Rules: Standard Skyscrapers rules. Also, some cells have been split into triangles, each of which must be filled with a number. In this puzzle, the numbers 1-6 must be placed in each row and column.

(The split cells are viewed in the order they are seen from a given direction, so the upper triangles are seen first from the left/top sides and the bottom triangles are seen first from the right/bottom sides.)

Answer String: Enter the 4th row from left to right, followed by a comma, followed by the 5th row from left to right. Enter the split cells in the order they are seen from the left (the upper triangle before the lower triangle).
