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.

Circled cells may be either shaded or unshaded, and each line (outside of the circled cell) must contain at least one shaded cell and at least one unshaded cell.

Circled cells combined with shaded cells along the attached line act as a valid thermometer clue with the circle as the bulb: digits must strictly increase along the line from the bulb to the tip. Any unshaded cells (other than potentially the circle) are ignored for the purposes of the thermometer.

Circled cells combined with unshaded cells along the attached line act as a valid arrow clue with the circle as the bulb: all unshaded digits along the line must sum to the digit in the circle. Any shaded cells (other than potentially the circle) are ignored for the purposes of the arrow.

6x6 Example:

The image below shows a sample 6x6 puzzle and solution with the same rule set.
Note: For 6x6 Sudoku, adjacent digits on a German Whispers line must have a difference of at least 3 (instead of the usual 5)
