Rules:
Normal sudoku rules apply.
Ratio (Kropki) dots: Cells connected by a black dot must contain digits in a 1:2 ratio (for example, 3 and 6).
Consecutive dots: Cells connected by a white dot must contain consecutive digits (for example, 3, 4, and 5).
X constraint: Digits in cells linked by an X must add up to 10.
Thermometers: Digits must strictly increase from the bulb toward the end of the thermometer.
Killer cages: Digits within a cage must sum to the number shown in its upper-left corner.
Relik cages (lines): No combination of digits on a red line may total the specified value.

Happy Solving !!!

Hello, congrats on making your first puzzle a unique and fun one.
I have one question though, I just solved your puzzle and I don't recall using the Relik cages. What was the idea of adding those to the puzzle?
~~~
Thank you. I just felt that without those cages the puzzle would feel empty. And also I wanted to try something new that I didn't saw too much in others' Sudoku's.

You should specify that the red cages are the 8 cells containing the thick red line; I started on the assumption that the red line *outlined* the cage (i.e. the cage is 3x3), and doing so results in the solution breaking the rules (you can sum 8 of the 9 numbers in at least one cage to get 37).
~~~
Yeah, you're right. I just wanted to stick to the original rule name - that is exactly Relik Cage, and not line. Maybe I should change it then to not confuse other people.
