The brief
Normal Sudoku rules apply. Numbers on red lines are at least 4 apart from their neighbors on the line. The number 5 does not appear on any red lines except in box 1. Numbers on gray lines are each a set of non-repeating consecutive numbers, in any order. Numbers with an X between them sum to 10. Numbers with a V between them sum to 5. Numbers with a white dot between them are consecutive. Not all possible X, V and dots are given. Numbers in cages sum to the number in the top left corner of the cage.
