Tapa (Borders) by Palmer Mebane

PDF

or solve online (using our beta test of Penpa-Edit tools; use tab to shift between shading mode 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: 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
