SudoKoach   -   Version   2.4

SudoKoach makes solving Sudoku puzzles more fun. It
does the tedious work for you, so you can concentrate
directly on finding the solution. SudoKoach generates
puzzles with six different levels of difficulty, so
you don't have to wait for tomorrow's newspaper to
start solving. You can also enter puzzles from the
newspaper, and SudoKoach will help you solve them too,
and you can print puzzles to solve later or to give to
friends.

SudoKoach doesn't solve the puzzle for you, it simply
figures out which numbers are possible in each
unsolved cell. This task is neither difficult nor
challenging--if you've solved Sudoku puzzles before,
you know that it is boring, time-consuming, and error-
prone, but absolutely necessary. With SudoKoach, you
don't need to waste your effort on this step. Instead,
you can immediately get to the fun part of solving
Sudoku puzzles: looking for the relationships among
cells that indicate solutions.
