Theme: 2024

Author/Opus: This is the 125th puzzle from our contributing puzzlemaster JinHoo Ahn.

Rules: (Hybrid of Fillomino and Snake Puzzles.) Divide the grid along the boundary lines so that every cell belongs to a snake. A snake is a one-cell-wide path at least two cells long that does not touch itself, not even diagonally. Circled cells must be at one of the ends of a snake. A snake may contain one circled cell, two circled cells, or no circled cells at all. Numbered cells must be part of a snake with a length of exactly that number of cells. A snake may contain one number, multiple identical numbers, or no numbers at all. Two snakes of the same length cannot touch each other horizontally or vertically.

      The smallest allowed region size in Snake Pit is 2. Your solution has a one cell region. Usually 1<2 but please tell us if this has changed. Otherwise we suggest using a logical process to solve our puzzles. Enjoy!
