- one German Whispers line: the digits have a difference of at least 5 to their neighbor(s)
- one Thermometer: digits increase, starting from the bulb. Oops, no bulb, you'll have to figure out at which end of the line the bulb is
- one Renban line: all digits along that line form a consecutive sequence in any order
Kropki: white dots link cells which have a difference of 1. Black dots link cells which have a ratio of 1:2. Not all possible dots are given.

I’m sure there’s a logical way to solve it with an intended solve path, but I ended up making some informed guesses and seeing how it shook out, backtracking as needed. Still loads of fun. Thanks for setting!

Just had the right feeling about the lines, so it all fell into place, and was very easy, but still a nice snack. Thanks for sharing.

For those who don't have the right feeling: there's a logic way to solve it ;-)
