5ud0ku - A Sudoku Game Midlet 
The
5ud0ku Midlet is a
J2ME game providing Sudoku puzzles (Number Place puzzle) for your java enabled mobile phone or PDA (check
J2ME Device List. The game requires at least MIDP 1.0 and CLDC 1.0).
From Wikipedia's SuDoku:
The aim of the canonical puzzle is to enter a numerical digit from 1 through 9 in each cell of a 9×9 grid made up of 3×3 subgrids (called "regions"), starting with various digits given in some cells (the "givens"). Each row, column, and region must contain only one instance of each numeral. Completing the puzzle requires patience and logical ability.

Motivation
For Sudoku quite a lot generators, solvers and helpers exist. There are also some good J2ME Midlets. The 5ud0ku Midlet is designed to match to
ivonne's and
case's player natures and it is free of charge. Most preferred of the features are the pencil mark support and the colored display of the numbers.
Some of the current features have been suggested or even implemented (especially by VladS) by people around the world and I am happy, that there is so valuable feedback from the community!

- Midlet Icon may not display on some devices (e.g. Motorola does not show 14x14, but requires 15x15). Won't be fixed
- possible bluetooth transfer of games to other devices (MIDP2+JSR82 Version) not yet targeted
- While in navigation mode (+), the digit '5' can be used to toggle to number input mode 'just once', once you enter that number, it should go back to navigation. (proposed by Syed Umais Akhtar) not yet targeted

To download the game to your mobile via WAP, point your mobile's browser to
http://wintermute.de/wap/sudoku/ .
Additionally you may download 5ud0ku (en,de,sk,hu,pl) at
GetJar
getting the jar/jad to your mobile without WAP Download
- For Nokia devices you will need a program such as the Nokia PC Suite. At least S40 3rd Edition also allows transfer of jar file using standard infrared/bt uploads (tested on Nokia 6233).
- For Motorola devices with a Memory Card (SD Card) you may put the jad and jar into the kjava directory of the card (it is a hidden directory!). Then select 'install new' in 'Games and More'. Now the game should show up (it worked on a Motorola V980)
- On other devices it may be suitable to just transfer the file via any means (bluetooth, IR, cable) to your mobile
Java Sources
Download the sources at
5ud0ku.src.zip. The archive contains all sources and some build information.
language translation
If you like to translate 5ud0ku to another language, you can do so by creating a new language file:
- Create your own 'dict_language-id' (e.g. dict_fr) file using an existing e.g dict_en as a template
- add the language-name and language-id to the lang file within 5ud0ku.jar
- pack the new dict and the updated lang into 5ud0ku.jar file
- update jad for new jar file size (if needed)
You also can send the file to me (
) and I will create the packed game.
Rules for the language files are: Use UTF-8 encoding (no BOM Signature) and check for the characters '=' and '|' in your file, since both are used as separators.
The source-zip is not updated for new language additions.
Confirmed devices
As mentioned above, in general the midlet should run on any J2ME enabled device with MIDP 1.0 and CLDC 1.0 at least. Devices, such as K610im, which implement CLDC and DoJa cannot run the game (There are some doja games available at
http://gnu-mode.sourceforge.net/).
Nevertheless, this list contains the
confirmed devices. (On some of the SonyEricsson devices the BACK key can be used to toggle pen/pencil)
