Theme: Pocket Puzzle
Author/Opus: This is the 52nd 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 All “4” clues have been replaced by tetromino letters, and must be connected to form a valid LITS solution (that is, identical shapes cannot touch along common borders).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 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 = 5:15, Master = 8:00, Expert = 16:00
