Sum Line through the Fog by Meggen033 https://link.sudoku-sleuth.com/SumLineThroughTheFog

Rules:

Normal Sudoku rules apply.

THERE IS ONE, AND ONLY ONE, blue sumline, where box borders divide the line into segments of equal sum. Distinct segments of the line within the same box count as separate sums to the same value.

Digits in a cage do not repeat and sum to the clue in the top left.

A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are given.

Adjacent cells connected with an X must sum to 10. Adjacent cells connected with a V must sum to 5.

The grid is partially covered with fog. Correctly placed digits will clear the fog around that cell. No guessing is required.
