or solve online (using our beta test of Penpa-Edit tools. Use left click to place 1 or 2 mines, right click (in cell) to mark unused, right click (on edge/corner) to mark a note; hitting tab will also enable a shading mode. If you want more solving options, turn off Penpa-Lite option.)

Theme: Field Goal

Author/Opus: This is the 2nd puzzle from guest contributor Fidel Zapico.

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:

Double Minesweeper by Serkan Yürekli

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

or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode, a number entry mode for placing Tapa clues, and the composite Yajilin mode where left click marks cells, right click marks dots in cells or X’s on edges, left click+drag draws lines.)

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.

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.

Snake Pit X by Ken Endo

Snake Pit by Ken Endo

or solve online (using our beta test of Penpa-Edit tools; use tab to alternate between a composite mode for line/edge drawing and a number entry mode.)

Theme: Clue Symmetry and Logic

Author/Opus: This is the 1st puzzle from guest contributor Ken Endo.

Rules: 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. Cells with an X cannot be an end of a snake.

Also see this example:

Snake Pit

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 “33553,44664”.

Theme: GMP (see Bridge Shapes)

Author/Opus: This is the 1st puzzle from guest contributor Gomatamago.

Rules: Shade some cells to make sunglasses. The sunglasses consist of a bridge (a given line, in red) and two lenses made out of orthogonally connected black cells that are symmetric with respect to the perpendicular bisector of the bridge. Two lenses may not share an edge, but can intersect at a point. Cells with the bridges are not shaded, except at the bridge ends. The numbers on the right and bottom edges of the grid indicate the number of shaded lens cells in that row or column.

Also see this example:

Sunglasses

Answer String: Enter the length in cells of each of the black lens segments from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma. This example has the key “22,121,12”.
