Killer Sudoku is based on the original Sudoku grid, with the same rules and numbers-1 to 9, but with an added mathematical challenge. The only difference is the killer Sudoku: additional numbers are given - the sums of values in groups of cells. The numbers contained in the group cannot be repeated. This variant also called "Sums Sudoku", "Sums Number Place", " Samunamupure ", "Kikagaku Nampure".
