Initial Setter Difficulty: 2.5-3 / 5*
*Additional difficulty information hidden below.

Normal Sudoku rules apply
Place the digits 1-9 so that they do not repeat in any row, column, or 3x3 box.

Disjoint Set
Cells in the same relative position in different boxes cannot contain the same digits.

German Whisper
Adjacent digits along green lines must have a difference of at least 5.

Thermometers
Digits on a grey thermometer strictly increase from the bulb end.

Difficulty

This is the type of puzzle that's impossible to accurately rate for difficulty. Experienced solvers will find it 1-2/5, but newer solvers may struggle and see it as at least 4/5.

Hint to start

4s, 5s and 6s are particularly tight around the top right boi (cell) in each box. It's useful to remember that 1s and 9s are only allowed in the top right boi once each, by disjoint.
