My debut puzzle.
Choosing a circular/spiral theme, I tried to make an entertaining puzzle, and I think it came out quite nicely.
- Sudoku: Normal sudoku rules apply.
- Kropki: Cells joined by a black Kropki dot have a ratio of 1:2
- Thermometer: Along this line, digits strictly increase starting from the bulb.
- Killer cages: Digits in a cage must sum up to the digit in the top left (if given) and cannot repeat.
- Renban Line: The purple Renban line contains a set of consecutive digits in any order.
- German Whispers: Any two cells joined by a green line must have a difference of at least 5.
- Region Sum: For each line, digits have an equal sum for each box they pass through.
Play it on Sudokupad here.

Very nice! THanks for sharing with us. If I may, most solvers prefer a one line (one row or one column) solution. But, it is of course your decision. Glad you decided to share. Very fun solve.
