The brief
Normal Sudoku rules apply. Numbers on arrows sum to the number in the pill at the center of the grid. Numbers may repeat on arrows. Numbers with an X between them sum to 10. Numbers with a V between them sum to 5. Numbers with a black dot between them are in a ratio of 2:1. Not all possible X, V and dots are given.
