The “Greater Than” Killer sudoku take killer sudoku to a new extreme. Some of the cages have no sum value attached. You must determine what the individual cells in the cage sum to by looking at surrounding regions. If there are relations between the cages (e.g., >, <, or =), the cages will obey those relations. Beware, these puzzles can be very hard!
