Logic Masters Deutschland e.V.

Normal sudoku rules apply.

Digits on a thermometer must increase from the bulb end.

Numbers in a cage must sum up to the indicated value.
Cages may contain numbers greater than 9 or less than 1,
but otherwise still cannot repeat any number.

Digits on the Yellow layer are Skyscraper clues -
they indicate how many digits you can see from that row/column,
where smaller digits are obscured by larger digits.

Numbers on the Purple layer are Sandwich clues -
they indicate the sum of the all the Sudoku digits
'sandwiched' between the digit 1 and 9 in that row/column.
Sandwich clues ignores any potential 1s or 9s in the Skyscraper layer.

Note : You do not need to fill in the Skyscraper and Sandwich layer
for the answer checker, but feel free to do so anyway.
