Theme: Clue Symmetry and Logic
Author/Opus: This is the 95th puzzle from our contributing puzzlemaster Serkan Yürekli.
Rules: Fill in every circle inside and outside the grid with a prime number. (All prime numbers inside and outside the grid are marked.) Then locate a numbered snake (a 1-cell wide path) that starts with 1 and goes to 45 (1 to 11 in example). The snake cannot touch itself, not even diagonally. Digits outside the grid indicate how many cells in that row or column are occupied by the snake.
Answer String: Enter the length in cells of each of the snake segments from left to right for the marked rows, starting at the top. Separate each row’s entry with a comma. The answer to the example is “3,11”.
Time Standards (highlight to view): Grandmaster = 3:45, Master = 5:30, Expert = 11:00
