SudoKoach

  SudoKoach makes solving Sudoku puzzles more fun. It does the tedious work of figuring which numbers are possible in each unsolved cell and provides tools to help you find the solution, including three levels of hints. It generates puzzles with six levels of difficulty, or you can enter puzzles from newspapers. You can print puzzles for solving later or to give to friends. Why not try it out? It is more fun to use SudoKoach than to read about it!
