Normal sudoku rules apply. Standard thermo, renban, little killer, and kropki (no negative constraint) rules apply. (Digits on a thermometer must strictly increase from the bulb end. Digits on a purple renban line must be consecutive, can be in any order, and must not repeat. Numbers outside the grid indicate the sum of the digits on their indicated diagonal. Digits on these diagonals may repeat when otherwise allowed. Neighboring digits marked with a white Kropki dot are consecutive. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. Not all dots are given.) I think this puzzle is 2 stars out of 5 for difficulty for many solvers. As always, comments welcome!
