Sudoku Killer 杀手数独

Sudoku Killer is a collection of Killer Sudoku puzzles, a wicked twist on the standard number-placement game. Regular Sudoku asks you to fill a 9 by 9 grid so each row, column and 3 by 3 box contains the digits 1 to 9. Killer Sudoku keeps all of those rules and adds dashed-line cages that must sum to given values without repeating a digit, a variant also known as Sumdoku, Mathdoku or Addoku.

The game packs 100 Killer Sudoku puzzles, with level progress saved automatically and cross-platform Steam Cloud saves, making it a solid addition to any puzzle collection and many hours of brain exercise.

It is presented in a beautiful minimalist design with multiple color themes and 10 relaxing ambient soundtracks, alongside Steam achievements and support for Windows, Mac and Linux.
