Snake Egg by Serkan Yürekli
or solve online (using our beta test of Penpa-Edit tools using a composite mode where left click inside cell shades square, left click + drag draws line segment, right click inside cell adds dot, and right click on cell edge adds an x.)
Theme: First Born Eggs
Author/Opus: This is the 93rd puzzle from our contributing puzzlemaster Serkan Yürekli.
Rules: Draw a snake (a 1 cell-wide path) in the grid whose head and tail are given by circled cells. The snake can touch itself diagonally, but cannot touch itself orthogonally or revisit any square. Besides the snake, the remaining cells must form exactly nine white areas, one of each size from 1 to 9. Numbers in the grid must be part of white areas of the indicated size.

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.
Time Standards (highlight to view): Grandmaster = 4:15, Master = 6:00, Expert = 12:00

A brilliant puzzle, hands down the best I’ve solved in months. Thank you.
Tricky start, then it goes rather smoothly. Nice.
I’m always amazed at these Snake Eggs, it’s incredible enough that one with so few clues could have a unique solution, let alone one with such a nice solving path..
That was… challenging (for a beginner, anyway).
I thought the answer verification instructions were a bit unclear. For anyone else doubting themselves after being told their solution was incorrect, if you have three segments in Row A of length 1,2,3 respectively, two segments in B of 3 and 5, and 1 in C of 4, you would enter “123,35,4” rather than “1,2,3,3,5,4” or “6,8,4”, as I tried repeatedly.
I hope this helps someone (and I’m not the only idiot to struggle with the box!)
I’m struggling to the ought most degree
Yep – the answer verification instructions are terribly unclear. I solved the puzzle correctly, but had to cheat to enter the stupid code!!!
