Theme: White Whorl

Author/Opus: This is the 8th puzzle from our contributing puzzlemaster John Bulten.

Rules: Standard Tapa rules. Also, the Tapa wall in this puzzle is made using one of each pentomino given below the grid with no overlaps. Rotations and reflections are allowed. (Note: There is no P pentomino here because it would violate Tapa rules).

Answer String: Enter letters for all pentomino segments from left to right in the marked rows, with one letter for each cell it appears in. Separate each row’s entry with a comma, and use CAPITAL LETTERS.

Theme: Pocket Puzzle

Author/Opus: This is the 5th puzzle from our contributing puzzlemaster John Bulten.

Rules: Variation of standard Nanro rules. Besides the cells numbered 4, identical numbers in differing regions cannot touch along common borders. All “4” clues have been replaced by tetromino letters, and must be connected to form a valid LITS solution (that is, identical shapes cannot touch along common borders). In other words: the final solution, including all numbered cells and tetrominoes, is a valid Nanro solution, and just the regions with tetrominoes form a valid LITS solution.

Answer String: Enter the length in cells of each of the segments labeled with characters from left to right for the marked rows, starting at the top. (Characters include both numbers and letters.) Separate each row’s entry from the next with a comma.

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

Theme: V is for Valvino (this puzzle was written for our patron Chris Green)

Author/Opus: This is the 74th puzzle from our contributing puzzlemaster Prasanna Seshadri.

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.
