Logic Masters Deutschland e.V.

Rules and constraints:

- Normal sudoku rules apply

- Thermo sudoku rules apply (i.e. along thermometers, digits must only increase from the bulb end)

- On the two cell thermometer, digits must sum to *at least* 9

- The bulbs of all *other* thermometers are volatile. The cells orthogonally adjacent to a volatile bulb must sum to *exactly* 4 times the value of the bulb (for example, a bulb with a value of 5 must have orthogonally adjacent digits that sum to 20). This does not apply to the two cell thermometer

- Bulbs in orthogonally adjacent boxes must contain consecutive digits (for example if the bulb in box 1 is a 3, the bulbs in boxes 2 and 4 must be a 2 or 4, and if the bulb in box 4 is a 4, the bulbs in boxes 1, 4 and 7 must be a 3 or 5). Applies to all thermometers
