Sudoku is a logical puzzle game, originally created in puzzle books and then made available in countless newspapers worldwide. The grid is 9 cells high by 9 cells wide and within the grid are 9 boxes each featuring 9 cells. The object is to fill in the numbers 1-9 in each row, column and box, but they must only appear in each one once.

Astraware Sudoku is suitable for players of all abilities and features include 6 levels of difficulty, pencilmarks in a choice of styles, optional completion and tracking of pencilmarks, and an advanced hint system to assist you by highlighting areas where progress can be made without giving away the answer.

Astraware Sudoku includes a selection of inbuilt puzzles of varying difficulty for you to evaluate. After registration the game allows you to add a range of additional pre-built puzzle packs. These extra packs are available free from http://www.windowsmobilesudoku.com for Windows Mobile® devices. The unlocked version of Astraware Sudoku includes a puzzle solver, so you can input any Sudoku from a newspaper or book and Astraware Sudoku can show you the solution or give you hints to help you play along.
