Killer Sudoku - sudoku game 1.7.9

Killer Sudoku, also known as sumdoku, addoku, cross-sum, or samunamupure, is a logical puzzle that merges elements of Sudoku and Kakuro. Its gameplay closely resembles traditional Sudoku, where the objective is to fill a grid with numbers while adhering to specific rules. Additionally, the puzzle requires that the sum of numbers within designated cages—areas separated by dotted lines—equals the number displayed in the upper left corner of each cage.

If you enjoy number puzzles or mathematical challenges, Killer Sudoku provides an engaging experience. It is somewhat more complex than standard Sudoku due to its additional constraints. To accommodate players of all skill levels, the game offers nine adjustable difficulty settings, from beginner to advanced. Even those unfamiliar with Killer Sudoku can quickly develop proficiency and mastery.

How is the game played? The aim is to populate the grid with numbers from 1 to 9 so that:

1. Each row, column, and subgrid contains each number exactly once.
2. The sum of all numbers within each cage matches the indicated sum in its corner.
3. No number repeats within a single cage.
