In a comment on an earlier post aboout Sudoku and Kakuro, Batman mentioned a combination of the two games known alternately as Killer Sudoku, Samunamupure or Sum Number Place. As in traditional Sudoku, Killer Sudoku is played on a 9×9 grid in which the digits 1-9 are placed so that each digit appears once in each row, each column, and each 3×3 grid (*nonet*). As in Kakuro, groups of cells (*cages*) add to given sums, and within each cage the digits must be distinct. Click to read more and see an enlargement of the game pictured here at the left.
