Crosslink by John Bulten

Theme: Boxy

Author/Opus: This is the 32nd puzzle from our contributing puzzlemaster John Bulten.

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:

Crosslink by Grant Fikes

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”.

Time Standards (highlight to view): Grandmaster = 7:45, Master = 10:15, Expert = 20:30

Theme: Clue Symmetry and Logic

Author/Opus: This is the 31st puzzle from our contributing puzzlemaster John Bulten.

Rules: Combination of Double Minesweeper and Slitherlink.

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

After solving the Minesweeper, convert these cells’ contents to numbers (use corresponding cells in additional grid), then draw a single, non-intersecting loop in the additional grid that only consists of horizontal and vertical segments between the dots, where the number inside each of these cells indicates how many of the four edges of that cell are part of the loop.

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

Time Standards (highlight to view): Grandmaster = 4:15, Master = 7:30, Expert = 15:00

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”.

Time Standards (highlight to view): Grandmaster = 5:00, Master = 7:30, Expert = 15:00
