The remained resources use JavaScript, and for work with them it is enough to enable its support in the browser. Usually it is included by default.
2. The first of resources has very modest potential. It allows to fill only empty fields of the table and does not allow to check whether correctly they are filled. Incorrectly entered digits can be removed, having selected the data entry field and having clicked Backspace. Having found the correct solution and having checked it manually, click on the link "Following Sudoku" for obtaining the new table.
3. On the second resource after loading of a Flash-applet select complexity level in the beginning. Then start the solution of a task. The correctness of filling of fields is checked automatically. Consider that in old versions of Flash Player the table can incorrectly be displayed.
4. At a game on the third website for generation of the new table click, depending on the desirable level of its complexity, the Easy, Medium, Hard or Very hard button. When entering digits it is automatically checked whether there is the same digit in a square, a column or a line and if it is available, then the program automatically shows, where exactly. Use the Undo, Print, Restart, Restore, Save and Check buttons, respectively, for canceling of the course, printing of the table, restart of a game, recovery of the saved session, saving a session and validation of filling. For start and a stop of a stop watch use the Start and Stop buttons.
5. The fourth resource is also supplied with function of validation of filling of fields. But error messages are displayed not automatically but only at the key press of How am i doing. Lines, columns and squares with the repeating digits are selected red and what digit repeats, it is necessary to check manually. Use the Pause button for a stop watch stop. When it is stopped, other keys disappear, and there is another - Resume puzzle intended for an output from the pause mode. To print the table, click Print and to generate new - Clear. And if to click Options, it is possible to change settings of a game, including complexity level.
6. On the fifth website instead of buttons three references are had: "Check the solution", "Show the solution" and "The following sudoku". Use the first of them if you are not sure that all fields are filled correctly, the second - if decided to be given and learn the correct answer, and a third - for generation of the new table.
7. Irrespective of what services of a resource you decided to use, when entering digits to fields be guided by the following rule: neither in line, nor in a column, nor in a square where this field is located, there should not be the same digit. If it is not possible to provide it, it is necessary to change contents of other fields of a line, a column or a square.
