Theme: Antisymmetric Borders (for Veep)

Author/Opus: This is the 38th puzzle from our contributing puzzlemaster Palmer Mebane.

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. (Cells missing a border that appear as larger shapes are entirely shaded or entirely unshaded. The count of shaded cells is always based on 1×1 squares, meaning if a “large” cell with missing borders occupies multiple 1×1 squares around a clue it would contribute 2 or more cells if shaded for that clue.)

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.

Time Standards (highlight to view): Grandmaster = 3:00, Master = 5:45, Expert = 11:30

Theme: X’s and O’s (for Jamie Hargrove)

Author/Opus: This is the 291st puzzle from Thomas Snyder, aka Dr. Sudoku.

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.
