Theme: Three’s Frame

Author/Opus: This is the 104th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Answer String: Enter the length in cells of each of the segments labeled with numbers 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 = 3:30, Master = 6:45, Expert = 13:30

Theme: Clueless

Author/Opus: This is the 174th puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Standard Nanro rules. Also, when any two numbers are orthogonally adjacent across a region boundary, the numbers must be at least two or more apart (i.e., they cannot be the same number or consecutive numbers).

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

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 All “4” clues have been replaced by tetromino letters, and must be connected to form a valid LITS solution (that is, identical shapes cannot touch along common borders).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: Clue Symmetry and Logic

Author/Opus: This is the 67th puzzle from our contributing puzzlemaster Prasanna Seshadri.

Rules: Variation of Nanro. Instead of the normal 2×2 rule, on this hex grid no three cells in the connected group can share a common vertex. All other rules still apply.

Answer String: Enter the length in cells of each of the segments labeled with numbers 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 = 3:30, Master = 5:00, Expert = 10:00
