Verbinden: F-puzzles link to XV Schlange VX Sudoku
Varianten: XV, Geändert VX, Schlange
1) Schlange
2) Normales Sudoku
Grüne Zellen stellen den Pfad dar. Blaue Quadrate sind Start und Stopp. Graue Zellen stellen Gesteine dar. Beachten Sie, dass die 4 X 6 rot ist, da sie nicht mit dem Rest der Schlange verbunden ist.
Examples (0 for Penpa+, 9 for f-puzzles):
ROW 2--Six multiplied by five equals thirty (6 X 5 3 0/9).
ROW 3--Five summed with zero equals five (5 V 0/9).
ROW 4--Three summed with two equals five, also two multiplied by four equals eight (3 V 2 X 4 8).
COLUMN 1--Sechs ist größer als fünf, auch fünf ist größer als drei (6 V 5 V 3).
COLUMN 2--Five ist größer als Null, aber auch fünf summiert mit Null gleich Null (5 V 0/9).
COLUMN 3--Zwei multipliziert mit drei Gleichsechs, auch sechs summiert mit vier gleich zehn (2 X 3 6 X 4).
COLUMN 4--Sieben ist größer Null, auch zwei summiert mit acht gleich zehn (7 V 0 2 X 8)
Lösungscode: Bitte geben Sie die 18 Ziffern der Spalte 8 gefolgt von Zeile 9 ohne Leerzeichen ein. Wenn Sie das Rätsel mit f-puzzle gelöst haben, ersetzen Sie bitte alle 9er durch 0's.

That was some puzzle! At the start I thought "no way", didn't have a clue how to make sense of all the rules, but slowly it started to unfold. Probably wouldn't be that hard if you were comfortable with the rules. As it was, I was extremely paranoid the whole way through... Towards the end, got stuck I seemed to be unable to make the path (X's) work and close to giving up, was sure I had made some mistake earlier on. Glad I stayed on :)

A tough one for sure. Thank you for sticking with it! The XV ? VX puzzles were fun to make even though they do not have many solves. Tell your friends if you liked it!

@BMEP I am glad you enjoyed it. I tried to make something logical that did not require forcing chains or endless trial and error. You have no idea how many grids I went through that we really pleasing except for 1 flaw that broke everything.

very nice puzzle! It's kinda hard to wrap the head around the rule set, but once you do, it's very enjoyable! thanks!

@henrypijames Originally I did not have a restriction on V sums but constructing a grid without it was exceedingly difficult. I also had a variant where the multiplication was in the direction of the path, but I thought that would be too hard for the solve. Another variant with simpler rules involving the inequalities but the path was entirely predictable. If you want to move the discussion to CtC discord, perhaps you could help me make a XV Snake VX that is enjoyable. I am sorry I let you down.

Thanks to henrypijames for addition to the (already complicated) rules.

@henrypijames I have a XV ? VX series and I struggled to find a way to make a snake type puzzle. Just finding a grid that worked took me two weeks. I will amend the rules as per your suggestions. You might like my arrow or killer puzzle better.

BTW, despite of how complicated they already are, the rules are actually incomplete. For example, it doesn't specify if a vertical sum relationship counts as sum or inequality (or solver's choice), which affects the snake's ability to slither over it. It also doesn't explicitly forbid leading zero as in 3x6=018. These omissions didn't matter here, but they could have (or maybe I oversaw some possibilities for leading zeros). And there might be more corner cases that I haven't thought of - when there are so many moving parts involved, the interaction becomes increasingly chaotic (as in chaos theory).

The idea is very interesting (and I'm a sucker for any snake sudoku), but the rule set is excessively complex (and partially arbitrary, in particular regarding which negative constraints apply and which don't) to the point of being distracting. When it requires more mental effort to keep the rules in my head than to actually solve the puzzle (and that's not at all an exaggeration), it takes out quite a chunk of the fun. Not to mention that I broke the puzzle a couple of times before realizing it was because I didn't understand the rules correctly (specifically, that a cell can be part of more than one X relationship) - which, unlike many other instances, is really excusable here given how crazy complicated the rules are.
I'd love to see this concept developed further by significantly streamlining the ruleset.

1) Yes, non grey cells cannot have snakesweeper properties. Example, a non grey 0 (zero) must touch the path. Determining the value of the rocks is a great place to start.
2) Your logic is sound.
3) The X cells and their product must be deduced. Example, R1C1 contains the start, therefore it must be part of an X somehow (either a sum or a multiplication).
If you get stuck send me a hidden comment and I'll get you along your way!

Does "All grey cells have been given" mean non-grey cells cannot have a minesweeper (or shall I say snakesweeper) digit?
Also, since all V's are upright, does it mean a horizontal paar of cells connected by a V cannot have an inequality relationship?
Finally, "This means the path is entirely constructed of all of the X's in the puzzle", but there are no X's in the puzzle?
