Yin Yang Multi-thermos
(Published on 8. March 2024, 20:20 by yttrio)
Rules:
Normal Sudoku rules apply.
Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.
Multi-thermos: Within the same color (shaded vs. unshaded), digits must strictly increase from the thermo bulb to the tip. Every time a thermo enters a new color, the values get reset (i.e., the value need not increase if the two cells along the thermo have a different color). A thermo may cross color boundaries any number of times (including never crossing a color boundary).
Additionally, the digit in each given thermo bulb gives the number of cells (including itself) that bulb sees of its own color in all orthogonal directions combined. Cells of the other color block the view.
6x6 Example:
The image below shows a sample 6x6 puzzle and solution with the same rule set.
Play the example 6x6 in SudokuPad.
Solution code: Column 8

This puzzle is approachable if you are familiar with the yin yang ruleset, but I personally found it easy to misinterpret the rules about multi-thermos :)
