Author/Opus: This is the 92nd puzzle from our contributing puzzlemaster Serkan Yürekli.
Rules: Draw a snake (a 1-cell wide path) from one dot to the other by moving horizontally or vertically between adjacent squares. The snake cannot touch itself, not even diagonally. All highlighted regions must be visited by the snake, and may be re-entered. If two or more highlighted regions have the same shape and orientation, then how the path passes through those shapes must be identical.
Answer String: Enter the number of cells used by each snake segment from left to right for the marked rows, starting at the top. Use both digits for any two-digit number. Separate each row’s entry with a comma.
Time Standards (highlight to view): Grandmaster = 2:00, Master = 3:45, Expert = 7:30
