Normal sudoku rules apply. Digits along an arrow sum to the digit in the circle. Cells separated by an X sum to 10, V sum to 5 and a red circle means they have the same polarity (odd/even). Not all possible X, V and red circle clues are given.
In addition: three or more consecutive cells in a row or a column cannot have the same polarity (odd/even).
