Killer Sudoku Free is a strategic number puzzle game that challenges your logical thinking. Like classic sudoku, you must fill the grid with numbers; however, in killer sudoku, you also need to ensure that the sum of numbers within each cage (areas surrounded by dotted lines) equals the number in the upper left corner of the cage.

If you enjoy number games or math puzzles, this Killer Sudoku is perfect for you! Whether you've played Sumdoku, Sumoku, Addoku, or Cross sum, give this one a try. It's an amazing combination of sudoku, KenKen, and Kakuro.

Killer Sudoku offers various difficulty levels suitable for both beginners and advanced players. The game features helpful functions such as the ability to add or remove notes during gameplay. Made a mistake? No worries - undo and hint functions are available to get you back on track quickly.

How to play:

1. Place numbers 1-9 into each grid cell exactly like in a classic Sudoku puzzle.
2. Different cages - groups of grid cells indicated by dotted lines.
3. The sum of all numbers in each cage should be equal to the number in the upper left corner.
4. The sum of all numbers in each 3x3 block, row, or column always equals 45.
5. Each cage, row, column, or 3x3 block cannot have repeated numbers.
