Normal sudoku rules apply. Any two cells separated by a knight's move (in chess) cannot contain the same digit. Kropki: digits separated by a black dot are in an 1:2 ratio (i.e. one digit is double the other); digits separated by a white dot are consecutive. XV: digits separated by an X must sum to 10; digits separated by a V must sum to 5. Region sum lines: region borders divide blue lines into segments. The values on each segment have the same sum, though this sum can be different for different lines. Maximum: cells with a square that has arrows pointing outwards have a digit greater than the 4 adjacent cells. Minimum: cells with a square that has arrows pointing inwards have a digit smaller than the 4 adjacent cells.
