Normal sudoku rules apply; i.e. the digits 1 to 9 need to be placed, once each, in every row, column, and 3x3 box.

The gray lines are palindrome lines, i.e. they contain the same digits backwards and forward.

Digits separated by a white dot are consecutive. Digits separated by a black dot have a 2:1 ratio, i.e. one is double the other.

Digits along an arrow sum to the digit in that arrow’s circle.
