How to Solve a Killer Sudoku Puzzle
Each puzzle follows the basic rules of Sudoku: the numbers 1 through 9 must appear once (and once only) in each column, row and subgrid. But the grid is also split into a series of dashed areas, each with a small indicator number in the top-leftmost square. The correct answers in each of those dashed areas will add up to its indicator number. Each puzzle has only one unique solution, and each can be solved using pure logic. Good luck!
