Rules:

Normal Sudoku rules apply.

THERE IS ONE, AND ONLY ONE, grey palindrome line which reads the same forwards or backwards.

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.

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