Logic Masters Deutschland e.V.

Rules: Normal sudoku rules CANNOT apply: no digit can appear exactly once in any row, box, or column. There are exactly nine of each digit. Digits cannot appear exactly once within a cage and cannot sum to the value indicated. Digits along the thermometer strictly do not increase from the bulb end: they may decrease or stay the same, but never increase. Numbers with a black dot between them cannot have a ratio of 2.

The puzzle can also be solved with f-puzzles and the CTC app. Have fun!
