"Solve any sudoku, however difficult it seems."
Surely more than once you've found a sudoku you couldn't solve, no matter what combination you tried. Now, with Killer Sudoku you have a tool to solve any sudoku, whatever the difficulty. With Killer Sudoku you will never leave a sudoku half finished!
Killer Sudoku has two ways of solving: normal in which the user indicates the space with the fixed number, and killer, in which the user gives the totals of certain segments. In other words you can indicate to the program that four spaces total 17, for example. There are also three speeds for solving: fast, ultra fast and interactive.
With Killer Sudoku there will be no sudoku that can resist you.
