Okoker Sudoku 4.2

Okoker Sudoku is a Sudoku game for Windows computers. Sudoku is a board game that has to be solved using logic, instead of math. So, don't get scared away by all those numbers. Okoker Sudoku's trial version allows you to play three different puzzles, which vary in difficulty. The paid version has support for several more puzzles and a lot of different options to create new puzzles. You can even save your puzzles and load them later.

This game does a good job of letting you input data into the puzzle. At the top of the puzzle is a list of numbers from one to nine and two other buttons: clear and hint. If you want to input data into one of the cells in the puzzle, you first have to click on the number that you want to input and then click on the empty cell. The "clear" button erases the number on the selected cell and it works the same way as inputting the number; that is to say, you have to click on "clear" and then select the cell.

All in all, this game is a good way to play Sudoku on the computer. The paid version allows for the creation of lots of puzzles, and the option to save is very interesting.
