Logic Masters Deutschland e.V.

I made this puzzle to honor one of my favorite podcasts! All inside jokes have been removed from the rules, but you can find a version with those references at the end of the page.

Rules:

Normal sudoku rules - Enter a digit from 1-9 in each cell without repeating in a row, column, or box.

Yin-Yang - Shade some cells such that the shaded cells and the unshaded cells each form a single orthogonally-connected region. No 2x2 area can be completely shaded or unshaded.

Killer cages - Digits in a cage cannot repeat, and the digits in unshaded cells in a cage sum to the number in the top left corner. (Digits in shaded cells are ignored.)

Thermometers - Digits in shaded cells on a gray thermometer line strictly increase from the bulb end to the tip. (Digits in unshaded cells are ignored.)
