The brief
Normal Sudoku rules apply. ARROWS- Numbers on arrows sum to the number in the arrow's circle. KROPKI PAIRS- Numbers with a white dot between them are consecutive. Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given. MAXIMUM- The gray cell containing greater-than symbols is greater than all four orthogonally adjacent cells.
