Logic Masters Deutschland e.V.

Rules:

Normal Sudoku rules apply.

Digits in a cage must add up to the total shown in the top left corner. Digits may not repeat within a cage.

Additionally, a 27 cell long slow thermometer must appear in the grid. The thermometer may only travel between cells that touch on a side or a corner. Digits may repeat along the thermometer, the thermometer may not branch, and the thermometer may cross itself as long as it does not use the same cell more than once.
