Rules:
Normal Sudoku rules apply.
Gray lines form palindromes (i.e. read the same from both directions).
Gray circles contain odd digits.
White dots connect consecutive digits. Black dots connect digit with a ratio of 2. All dots are given. (Note: a connected 1 and 2 can either have a black or a white dot between them)
Solution code: Enter the top row of the solved puzzle to verify your solution (no spaces or anything in between, just digit after digit, i.e. 764125389 )
