Logic Masters Deutschland e.V.

Rules:

Sudoku - Fill the grid with the digits 1-9, such that every row, column, and 3x3 box contains every digit.

Whisper's Thermometers - Along a green thermometer, each digit is either greater than the previous digit OR at least 5 less than the previous digit (starting from the bulb end). ex: 139468 would be a valid way to fill a 6-cells sequence on a Whisper's Thermometer.

Stacked XV - Digits in cells connected by a V sum to 5. Digits in cells connected by an X sum to 10. There are two V's that are actually "stacked" X+V clues instead (to be determined by the solver); digits in cells connected by a "stacked" X+V instead sum to 15.

Anti-knight - Cells separated by a "knight's move" (2 cells in one direction and 1 cell in a perpendicular direction) do not contain the same digit.
