Theme: Snakes in a Bee Hive

Author/Opus: This is the 6th puzzle from guest contributor Joseph Howard.

Rules: Variation on Snake Pit (new rules in italics). 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. Each snake houses a word (given below the grid) with one letter in each cell. Some letters are given. Snakes of the same length cannot touch each other horizontally or vertically.

Also see this example:

Answer String: Enter the letter placed in each cell in the marked rows from left to right, separating the two rows by a comma. Use CAPITAL LETTERS!

Theme: 2×

Author/Opus: This is the 296th puzzle from Thomas Snyder, aka Dr. Sudoku.

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 the example, the answer is “022102,002000”.

Theme: Boxy

Author/Opus: This is the 30th puzzle from our contributing puzzlemaster John Bulten.

Rules: Place a mine into some of the empty cells so that each number represents the total count of mines in neighboring cells, including diagonally adjacent cells.

Answer String: For each cell in the marked rows, enter a 1 if it contains a mine and a 0 if the cell is empty (or a clue cell). Separate each row’s entry from the next with a comma. The format will resemble “0010101000,1110010101,1000011011”.

Theme: Mix and Match (Each set of row clues is also a set of column clues)

Author/Opus: This is the 8th puzzle from guest contributor Chris Green.

Rules: (Style created by Chris Green as a combination of Cross the Streams and Tapa rules.)

Shade some empty cells black to create a single group of black cells that are all connected to each other through their edges. No 2×2 cell area within the grid contains all black cells.

Numbers and symbols to the left/top of the grid represent all unshaded cells in the grid in that row/column in order, either from left to right or from top to bottom. The numbers and symbols represent the value of Tapa-style clues inside the grid, specifically the length of consecutive shaded blocks in the neighboring cells. If there is more than one number in a cell, then there must be at least one white (unshaded) cell between shaded groups.

The three symbols indicate different kinds of missing information.
– A question mark (?) represents a single missing positive integer as part of a clue (either alone or in combination with other numbers/question marks).
– An octothorpe (#) represents a single white clue cell which may have any combination of values including a single number or multiple numbers.
– An asterisk (*) represents an unknown number of white clue cells, including one, multiple, or no clue cells at all. Any clue cells indicated by an asterisk can have any combination of values including a single number or multiple numbers.

Also see this example by Thomas Snyder:

Answer String: Enter the length in cells of each of the black segments from top to bottom for the marked columns, going in order from A to B to C to D and separating each entry with a comma.
