Sudokumaster is a Sudoku mobile game developed with Silverlight for Windows Phone devices. The game is a logic-based, combinatorial number-placement puzzle with nine 3x3 grids each containing all the digits from 1 to 9. In the beginning only some of the numbers are placed in the grids and the player needs to figure out the correct positions for the missing numbers.

The application is a rewrite of the Qt Sudokumaster application for Symbian and Maemo devices.

Preparations

Make sure you have the following installed:

• Microsoft Visual Studio 2010 Express for Windows Phone
• The Windows Phone Software Development Kit (SDK) 7.1 http://go.microsoft.com/?linkid=9772716

Build on Microsoft Visual Studio

An empty Sudoku game board is displayed after the application is started. The menu at the bottom of the screen contains two buttons, New Game and Highscores. Press the New Game button to start the game. Tap on an empty cell on the grid, and a dialog pops up where you can select a number or clear the value of the cell. Only the empty cells and the cells the player has set earlier (cells with white numbers) can be manipulated. The objective of the game is to fill the board with numbers between 1 and 9 according to the following guidelines:

• A number can appear only once in each row
• A number can appear only once in each column
• A number can appear only once in each region

A region is 3x3 squares, and the board is divided into 3x3 regions identified by lighter and darker cells.

Below the board are three icons and numbers besides them; number of moves the player has made, remaining empty cells, and game time.

The game ends when all the cells are filled. If a new high score was achieved, the player's name is queried.
