Rules:
Place the digits 1-9 in each row, column and box.
Compound Thermometers: Box borders split grey thermometer lines into segments. Starting from the bulb, the sum of each segment must increase. Additionally, within each segment, starting from the original bulb, digits must also increase.
Entropy Zones: Within red cages every 2x2 square* of cells must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).
*incomplete squares (such as in the bend) are exempt.
Kropki Dots: Digits connected by a white dot are consecutive. Digits connected by a black dot are in a 1:2 ratio.
Love, Brigitte
Solution code: Row 6 from left to right (9 digits in total)
