Our Review:

HoDoKu is an open source program and runs with Java on Windows, Linux or Mac. It allows you to generate sudoku puzzles in five different and configurable difficulty levels. It also includes a solver and an analyzer to help you solve the puzzles.

While playing the game, you can select to view a summary of solving techniques and the solution paths. When you click on a solution path, it highlights the steps on the corresponding grid to help you analyze the game. You can also opt for a practising mode, tick one or more techniques to be included in a new puzzle. All these features make HoDoKu not only a game to play but also a nice tool for learning and honing your skills in the game as well.

Other useful features include redo/undo steps, show candidates and invalid values, next vague or concrete hints and more. Puzzles can only be saved in a proprietary hsol format or a png image format for printing out, whereas import and export of games from/to other formats are not available.
