A little puzzle inspired by the rules of this puzzle by Jonesy. That puzzle is also a good way to get more familiar with the rule before trying this one.

Puzzle rules:

• Normal sudoku rules apply.
• Digits in the same position in each box belong to the same modular group (147/258/369). For example, if the first digit in box 1 is a 5, the first digit in every box is 2, 5 or 8.
• Full Black Kropki: Digits separated by a black dot have a 1:2 ratio. All possible black dots are given.
• Thermometers: Digits on a thermometer must increase from the bulb.
