Warming Killer Lines / Erwärmung der Killerlinien
(Published on 2. February 2022, 18:07 by PDN777)
Normal sudoku rules apply. Digits on a killer line must sum to a specific number as determined by the line's color, and may not repeat on the line. The sums are as follows: green -- 24; red -- 15; yellow -- 12; violet -- 10. Digits on a thermometer must strictly increase from the bulb end. Digits must not repeat on the main diagonals. I think this puzzle is one star out of five for difficulty for many solvers. As always, comments appreciated!

Another fun puzzle to solve, thanks to PDN. Nice and steady flow of digits ...and suddenly the grid is full.
...on to the next one!

Easy puzzle. I would point out that non-repeat digit constraint along lines is not necessary for thIs puzzle as all lines are inside sudoku boxes.

Pretty straight-forward. Thanks for putting this together.
** Yes, hence the one star. This was actually the first killer/sum line puzzle I did - proof of concept really. Have a look in my catalog for several others, if you like the constraint, for harder puzzles. Beware -- sum lines can repeat digits; killer lines cannot.
