Playing the Game

Navigate across the screen (UP, DOWN, LEFT and RIGHT) using the track ball, track wheel or arrow keys on your phone.

A highlight box will indicate which empty square you are on. If you would like to temporarily store multiple values in a square, select the square and then press the different number keys. The square will immediately take on multiple values. Use '0' to clear the last value you entered, or use any one of the entered numbers to select that and discard the rest.

Pen and pencil modes help you keep track of entries that you are sure of and entries you are doubtful about. All entries first appear in 'pencil' mode. Typing the number again switches to 'pen' mode. You can type the same number again to switch back once again to 'pencil' mode.

When playing the game, you can press the track ball, track wheel or fire key, and get the menu options. You can select the various Hint and Solve options to aid you in solving the puzzles.

Show Errors help you to find out the cells with wrong values. Undo regains the previous operation that was done. Fill cells helps to display all the possible values that can be entered in a grid.

Sudoku:
Fill all empty squares so that the numbers 1 to 9 appear once in each row, column and 3x3 box.

Sudoku Mini: Fill all empty squares so that the numbers 1 to 6 appear once in each row, column and 3x2 section. 

Sudoku X:
Fill all empty squares so that the numbers 1 to 9 appear once in each row, column and 3x3 section. The diagonals also must include numbers 1 to 9.

Kakuro:
Insert numbers from 1-9 in to the empty cells to tally up to the sum listed in the triangles (across or down). Each number must appear only once in a sum, and just like a crossword there's a grid of filled blocks and clues to solve.

Sudoku Fusion:
Fill in the color matched squares with numbers 1-9 so that they add up  to the number clue appearing in the first empty color square. As you complete the sums, ensure each 3x3 section includes each number from 1 to 9 as in Sudoku. When all the sums add up and the sections are complete, the puzzle is solved. 

Key Assignments & Navigation Short Cuts

  • Use the arrow keys/trackwheel on your phone to move across the puzzle (UP, DOWN, LEFT and RIGHT).
  • Use the number keys on your phone to enter a number in the square.
  • Press the "0" key to clear a number from a square.
  • If your phone has a track wheel, then you can press the "ALT" key whlie moving the track wheel to navigate LEFT-RIGHT, while without the "ALT" key, the track wheel navigation is UP-DOWN.

TIPS AND TRICKS

General:

  • Pen and pencil modes are useful to keep track of entries you are certain about and those that you are unsure about. When you first make an entry on the grid, it is in the pencil mode. Typing the same number again, enters the number in the 'pen' mode. You can type in the number once again, to switch back to the 'pencil' mode.
  • If you would like to temporarily store multiple values in a square, select the square and then press the different number keys. The square will immediately take on multiple values. Use '0' to clear the last value you entered, or use any one of the entered numbers to select that and discard the rest.
  • When playing the game, you can press the SOFT KEY marked Menu and select “Hint” from the options to get the solution for an individual square or “Solve” to solve the entire grid.

Sudoku, Sudoku Mini and Sudoku X:

  • Try not to guess - it can lead you up paths that can make the puzzle virtually unsolvable. Simple logic is all that is required. Ask yourself questions like: 'if a 5 is in this box, will it go in this column?' or 'if a 6 is already in the row, can a 9 go in this square?' Look for the lone number - if there is only one place for a number to go, then it is true for the box, the row and column it is in. If two squares in a section contain an identical pair of numbers and no other squares in the group contain those two numbers, then other numbers in those two squares can be safely excluded. Think of a puzzle as a maze. Easy and moderate puzzles offer a straight path to completion. Tough puzzles may have dead end and multiple paths.

Kakuro:

  • Look for the sets which have the lowest number of combinations. These are normally 2 and 3 square sets. Certain numbers and combinations can only be made with 1 combination of numbers. For example, a set of 4 squares with a total of 10 can only be made with a combination of 1, 2, 3 and 4.The only 2 digits that can combine to make 16 are 9 and 7 (8 and 8 is not allowed as the same number is repeated). There is never a 2 digit 18 combination because you need either 2 nines or a 10 and an 8, which isn't allowed. Start with combinations having very low or very high totals for the number of digits, especially where they intersect. A 3-digit 23 intersecting a 2-digit 16 can only be 9 as the only possibilities are 6-8-9 and 7-9.
