You could even use another sudoku generator and send the generated sudoku to the game through a parameter of its URL. If we want to configure it even more, we can set or edit some parameters included in the generated URL (you can read more about it in the game's website). We just need to get the URL (which will be used in the SRC parameter of the IFRAME tag) generated by the "Share" option (inside the configuration menu). The game is specially designed to allow to be used inside any other web site (by using an IFRAME, for example). Through the new configuration menu, you can choose language (in the case you are not happy with the auto-detected one), disable autosave, change the way the game helps you, set the number of seconds the on-the-fly calculated solution is displayed and disable some visual effects (in order to improve performance).
It can be controlled by mouse (or finger on mobile devices) and/or keyboard (gamepads on some devices as Wii or some remote control on some TV devices should also work). The new improved version (0.75a) comes with some bug fixes, using some CSS3 effects and HTML5, a better mobile devices support, autosave (using Web Storage and falling back to cookies if not supported), it is printer-friendly, it adapts automatically to any screen resolution (200 x 180 is the minimum), improves browser integration (can be included easily in any web site with an IFRAME, for example), is available for and ported to many platforms and can be ported to many more (it is compatible with Apache Cordova, PhoneGap Build, PhoneGap, Intel XDK, BlackBerry WebWorks, virtually any browser extension guidelines and so on), and is now multilingual with language auto-detection (main version includes Chinese, English, Catalan and Spanish languages and it is very easy to add new ones).
This game has been tested under BeOS, Linux, NetBSD, OpenBSD, FreeBSD, Windows, Mac OS X, BlackBerry Tablet OS, Android, iOS and others. Other modified and adapted versions of this game can be found on the Internet, including one Opera widget and several translations. You can find a lot of translations in other languages over the Internet, including German, French, Portuguese, Czech, Hungarian and Chinese. Official languages are Spanish and English. The game has been quite successful and famous, included for instance in a famous Spanish online newspaper called " Libertad Digital".
This game doesn't use any image at all, just pure HTML and CSS. You can also change the game behaviour easily by editing many of the configuration variables which are at the beginning of the script. It is not only a normal sudoku game but also a sudoku solver, allowing users to introduce their own sudoku in order to solve it. The game will generate sudokus and the player will have to solve them. It is my fifth DHTML game and was made in mid 2006. Open source Sudoku (game, generator and solver) totally written in DHTML (HTML, CSS and JavaScript).
