It's no secret that Astraware create great PDA games, so the news that they have brought their own version of Sudoku into the arena should be great news for any fans of the brain-teasing game that currently seems to have exploded into popularity violently enough to bring Carol Vorderman out of the woodwork with a fresh face clawed from a supermodel and glued to her own aging skin.

Astraware have also created a dedicated website at http://www.palmsudoku.com. The site gives lots of information about how to get started playing Sudoku, a range of techniques for solving the puzzles (even the really hard ones), and it will include additional pre-built puzzle packs which registered users can download and use.

In case you're wondering why Astraware decided to make a Sudoku game when there are already a few out there, you may like to read this post by Howard Tomlinson, their CEO, on the Astraware forums.
