Here is a tutorial sudoku teaching the equal sum line constraint and aimed at first-timers. It is accessible, though not the easiest puzzle. When following the steps, it is build to showcase some common logic of this line type. However, if you feel like it, or for more experienced solvers, feel free to solve it any way you like, there are no rules! (Except the following...)
Rules: Normal sudoku rules. Box borders divide each blue line into segments with the same sum. Different lines may have different sum.

Great tutorial, once I figured out how to (and how not to) pencil mark two-cell equal sum lines.
