Logic Masters Deutschland e.V.

This puzzle started by drawing random thermometers into the grid until there was only one sudoku solution. That resulted in a puzzle that is difficult to solve without looking ahead a bit. You could spend your time guessing, or you could find they key cells and slowly find the only possible solution. If you need a hint, send me a hidden message.

Normal sudoku rules apply.

Digits on a thermometer increase from the bulb to the tip.
