How to use the Sudoku Android Application
Sudoku Player
The Sudoku Player is for doing puzzles.
Tap on a cell where you want to enter a number, when the cell has turned light blue tap the number button below.
To change a number you have filled in, tap to choose the cell, then tap on a number button. If you tap the same number or the Del button the number disappears.
When you tap the pencil button,
the button changes to the memo button,
and the mode changes to "Memo mode". In memo mode, you can enter/delete up to 9 memo numbers.
When you tap the memo button, the button changes to the pencil button, and the mode changes back to the "Input mode".
If you enter a large number (Input mode) in a cell with small memo numbers, only large numbers appear. When your Sudoku program thinks about whether your solution is correct or not, memo numbers on the screen are ignored.
If you wish to quit a problem, push the back key on your device, and a dialogue box will ask if you wish to "Save" the puzzle, to go back and solve it later; or "Quit," to abandon the puzzle.
Tap on number buttons to enter numbers in cells.
When all 9 of the same number (except memos) are in the 9x9 board, the button for this number turns gray.
Tap on the "Del" button to delete numbers in cells you selected.
Switch the mode by tapping on the "Pencil" or "Memo" buttons.
After finishing a problem, tap the "Check" button and the screen will say "Congratulations" - if your solution is correct. If your solution is not correct the puzzle will show one point where it is not correct, then tap the "Check" button to continue to solve the puzzle.
