Killer Sudoku X 2.1.1

Killer Sudoku is a challenging twist on the classic game of Sudoku. It follows the same rules where players must place numbers 1 through 9 in each column, row, and 3x3 box, without repeating any. The twist comes in the form of smaller outlined boxes on the board, each assigned a specific number that the enclosed cells must add up to without repetition.

The game now also includes Regular Sudoku mode, allowing players to switch between the two variants within the app.

• Random puzzle generation for endless gameplay
