Theme: Mirror

Author/Opus: This is the 67th puzzle from our contributing puzzlemaster John Bulten.

Rules: Variation of Nanro. Label some cells with numbers to form a single connected group of labeled cells. No 2×2 group of cells may be fully labeled. Each label number (including black given numbers) must be equal to the total count of labeled cells in that bold region, and all bold regions contain at least one labeled cell. The given numbers in gray indicate how many cells are labeled in that region (but not necessarily which cells are labeled). When two label numbers are orthogonally adjacent across a region boundary, the numbers must be different.

Difficulty: 2 stars

Time Standards (highlight to view): Grandmaster = 1:45, Master = 3:00, Expert = 6:00

Solution: PDF
