Normal Sudoku rules.
Fog of war: fog covers the grid. Correctly placing a digit removes fog from the surrounding cells. No guessing is required.
Leap frog rule: frogs cover the grid. Adjacent digits across frogs leap in value and differ by exactly 3. All possible frogs are given.
Auf Deutsch: gewöhnliche Sudoku- und Nebel-des-Kriegs-Regeln.
Durch einen Frosch getrennte benachbarte Ziffern unterscheiden sich um genau 3
Alle möglichen Frösche sind gegeben

Cute! I love puzzles with negative constraints like this, and such adorable clues :D
[Thanks for the comment. I love using negative constraints. Please try my “All the same and never 4”. One streamer called it “the mother of all negative constraints.”

I rated this 1/5 difficulty
Cool idea for a FOW puzzle! Took me a minute to understand how this was basically a modular coloring puzzle, but was really pleasant to solve upon realizing that.
I also didn't remember that there was a negative constraint for frogs when I began solving, and spent a solid 2-3 minutes completely lost as to how this was possible - but that was completely my fault for not reviewing the rules thoroughly!
Really cool puzzle idea & great setting!

Cool themed puzzle. I go for 2 star difficulty here. It helped me having solved modular line puzzles and those with negative constraints. Very tricky for an 1 star. Had great fun solving anyway thx.

Maybe i am blind.
I can't see a link or an image for the puzzle
EDIT: The link and image are missing for German users. If you change language to English ... they appear.

A very beautiful work. Platinum nailed it.
[Im very pleased to see your name in the solvers list on one of my puzzles again. I think you helped me on Bat and Berg or some other puzzle months ago,]
