Dutch Flat Mates (Entropic Snake) (Flinty & Palpot)

(Eingestellt am 19. Juni 2024, 11:30 Uhr von Flinty)

This is a collaboration, jointly set by myself and palpot.

Normal Sudoku rules apply.
Place the digits 1-9 so that they do not repeat in any row, column, or 3x3 box.

5s live in Dutch Flats
All 5s in the grid must have a '1' directly above it or a '9' directly below it. It may have both, but it doesn't need both.

Entropic Snake
- Draw a one-cell-wide snake of orthogonally connected cells.
- The snake can't touch itself, not even diagonally.
- Circles are on the snake.
- Squares are not on the snake.
- A digit in a circle/square counts how many cells of the same type (snake/non-snake) it sees in the row and column, including itself. The other type blocks vision.
- Every three cell sequence on the snake contains a low digit {1,2,3}, a middle digit {4,5,6} and a high digit {7,8,9}.

Special Thanks
This puzzle was set for Scojo's weekly prompt, which was a twitch channel points redeem from black_doom with the only requirement being collaboration!
Thanks again to Palpot for co-setting this puzzle.
The circles/squares idea was borrowed from many gdc loop puzzles.
But please note that today's puzzle is a snake, not a loop!
We made that mistake a few times in the early setting, as we weren't sure which to use - lol.

The digit in R1C1 is forced whichever way it chooses to connect. This gives enough entropy information get a good grip on the top of your snake.

Combination of some of my favorite rulesets in a great way. Only problem I had is that I have one set of coloring rules for DFM (tracking eligible 5 positions and the status of the 1 and 9 in the columns), coloring rules for entropy, and then coloring rules for snake/not snake so things looked crazy until the snake had resolved itself.

Very cute puzzle! Once i got my first toe hold, the rest flowed very naturally until i forgot about the "flat mates" constraint at the end. But once i remembered that, the rest came quite naturally. Nicely done!

Very nice! I was almost finished and got stuck, read the rules again and remembered there's a flat mates constraint... The rest was just filling in.
