Rules:

• Normal Sudoku rules apply.
• XV: An X connects digits that sum to 10, and a V connects digits that sum to 5. Not all X's and/or V's are necessarily given.
• German Whisper: Digits along a green line must have a difference of at least 5.
• Numbered Rooms: A clue outside the grid indicates the digit that must be placed in the Nth cell in the corresponding direction, where N is the digit placed in the first cell in that direction. This includes the numbers that would be written near X's on the edge of the grid. i.e., an X on the edge of the grid connects the digit in the cell it touches with an invisible numbered rooms clue. The sum of both numbers must equal 10, and the digit outside the grid must be a valid numbered rooms clue.
