The brief
Normal Sudoku rules apply. Numbers on arrows sum to the number on the pill attached to that arrow. Numbers may repeat on arrows. Numbers with an X between them sum to 10, a V between them sum to 5, a white dot between them are consecutive, a black dot between them are in a ratio of 2:1. Not all possible X, V and dots are given. Numbers with a gray circle are odd. Yellow highlights are the cells not on arrows.
