Normal sudoku rules apply. Digits in cells connected by a V sum to 5. Digits connected by a black dot are in the ratio 2:1. Digits connected by a white dot are consecutive. Digits in cages sum to the number in the corner. Digits on an arrow sum to the digit in the circle. When the grid is rotated 180 degrees, the digits in the corresponding cells are in the ratio 2:1 or both are digits that can never be on a black dot (eg. if r3c1 is 1 then r7c9 is 2).
Solution code: Row 4 and Column 6 (no spaces)
