Equal Snake Pit
(Published on 4. October 2020, 11:45 by Phistomefel)
- Draw seven snakes in the grid, each of them seven cells long and none of them intersecting.
- A snake is a path, which is one cell wide, does not branch and does not touch itself orthogonally.
- The circles drawn in the grid are endpoints of snakes.
- Not all endpoints of snakes are given. A snake can contain no circle, one circle or two circles.
The puzzle is also available online via Penpa Plus. Have fun solving!
For the entry into the puzzle an argument is needed, where I can not estimate how hard it is to discover. If you have difficulties to find a way into the puzzle, just mark the lines below, which contain a hint:
A checkerboard pattern can help to give a new perspective to this puzzle. Here is a link to the puzzle on Penpa Plus with an underlaid checkerboard pattern:

Solution code: For each row from top to bottom the length of the largest horizontal snake segment and then for each column from left to right the length of the largest vertical snake segment.
In the example the code would be: 3223331234

Schönes Rätsel. Der Charme liegt ja eigentlich darin, das Einstiegsargument zu finden. Ich würde den Hinweis (den ich allerdings (wie vermutlich alle) nicht gelesen habe (Rätslerehre)) weglassen. Der Hinweis auf die Suche nach einem Einstiegsargument ist völlig ausreichend. Danach war es auch ein bisschen (kurzes) Trial and Error, Das Schöne ist also die Schlangen mit dem gefundenen Hinweis zu erlegen... Vielen Dank!

Managed to solve this, but I didn't use much logic. Just trial and error until I stumbled on the solution.

Lovely puzzle!
I didn't need the hint, because the same idea is useful in one of my puzzles: https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000478
