In Sudoku, players fill in every cell of a 9x9 grid in such a way that every row, every column and every 3x3 box contains one instance of the numbers 1 to 9. There are no duplications.

Every Sudoku grid begins with a certain amount of pre-placed numbers, called "givens," that help you solve the puzzle. The givens cannot be changed.

After you finish the grid, you are told if you entered the correct solution. If you made errors, you can correct them, but the game finishes once you complete your corrections. You are not warned about new mistakes.

You can annotate your Sudoku grid by entering a list of candidate numbers for any given cell. Press the Pen/Pencil key to enter Pencil mode, and write up to 6 candidate numbers in the cell.

Candidates can be written as numerals, or as dots corresponding to the number keys on your keypad. You can select the annotation style from the Options menu.

JAMDAT Sudoku offers four kinds of grid helpers to assist you in solving a grid:

• Area Shade - When you select a cell, the row, column and 3x3 box containing that cell is highlighted.
• Number Shade - Press the asterisk (*) key to highlight every cell containing the number of the currently selected cell. Further key presses from this cell or key presses from an empty cell highlight all numbers on the grid in sequence.
• Show Errors - When the Show Errors option is turned on, incorrect cell entries are immediately highlighted. Each error revealed by this feature reduces the point value of the grid.
• Cell Hint - Press the pound (#) key to highlight one of the cells in the Sudoku grid that is solvable, given your current entries. Each Cell Hint reduces the point value of the grid.

To create new grids in JAMDAT Sudoku, select "Newspaper Grid" from the Main menu and press Select.

The editor tutorial screen appears. Press Next.

The Editor screen appears. Use the D-pad to move the cursor, and press the 1-9 keys to enter the givens for the grid. Press 0 to clear a cell, and press the pound (#) to clear the entire grid.

You must enter at least 22 givens for the grid.

Once you have entered the givens, press Done. JAMDAT Sudoku validates the grid to ensure that there is only a single correct solution to the grid.

When the grid is validated, you can play the grid.

Logic points are earned by correctly solving Sudoku grids in Regular Grids mode. The base value of each grid depends on the difficulty level. Errors made while the Show Errors option is active, and cell hints reduce the final value of the grid.

As you accumulate Logic Points, you earn additional Sudoku grades and unlock new color schemes.

There are seven different Sudoku grades. Each grade unlocks a new color scheme for your grids.

• Blue Sudoka 0 pts
• Red Sudoka 100 pts
• Green Sudoka 400 pts
• Orange Sudoka 1,000 pts
• Purple Sudoka 2,500 pts
• Brown Sudoka 5,000 pts
• Black Sudoka 10,000 pts

The Black Sudoka grade also unlocks a new difficulty level - Insane.

Solve one of thousands of grids generated by the game, and earn Logic Points for each correctly completed grid.

Enter Sudoku grids from other sources, such as the daily newspaper, or even grids of your own invention. JAMDAT Sudoku validates all grids to verify that they have a single correct solution. You do not earn Logic Points for these grids.
