Completing a Killer Sudoku puzzle on my iPad to teach and demonstrate techniques for solving challenging games

Here's a breakdown of the rules: • Standard Sudoku Rules: The basic Sudoku rules apply: Each row, column, and 3x3 box must contain the numbers 1-9, without any repeats. • Killer Cages: Cages are groups of cells enclosed by dotted lines. Each cage has a small number in its top-left corner that represents the sum of all the digits within that cage. • No Repeats within Cages: Similar to Sudoku, numbers cannot repeat within a cage, row, column, or 3x3 box. • Initial Numbers: Unlike regular Sudoku, Killer Sudoku typically starts with no initial numbers given. Instead, the cage sums act as clues. • Focus on Sums: The core strategy involves figuring out which combinations of digits can add up to the cage sum.
