RULE SET:

Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.

All the lines in the puzzle, colored GREY, consist of either Renban, German whisper or Region sum lines. There are at minimum TWO lines of each type. It is up to the solver to determine which lines are which type!

Digits along a RENBAN line must be a set of consecutive non-repeating digits, and may appear in any order.

Adjacent digits along a GERMAN WHISPER line must differ by at least 5.

For each REGION SUM line, digits on the line have an equal sum N within each box it passes through. Region sum lines must cross box borders, they are not confined within a single box.

KILLER CAGES: The sum of the cells in a cage must equal the total given for that cage. Digits in a cage do not repeat.

Kropki dots: Black dots are a 1:2 ratio. Not all dots are given.

XV pairs. Cells separated by a "X" must equal to 10, and cells separated by a "V" must equal to 5. Not all XV pairs are given.
