About Little Killer Sudoku
Little Killer Sudoku places clues outside the grid along with a diagonal arrow. The arrow points to a diagonal stripe of cells, and the clue gives the sum of all digits along that diagonal. Unlike standard Killer Sudoku cages, digits CAN repeat on Little Killer diagonals as long as they don't violate the row/column/box rules. This makes the arithmetic different from standard cage solving.
