A rather simple but easy to use sudoku player in PocketC, this applet does not generate sudoku puzzles and it does not solve them for you. However, if you find a sudoku puzzle in a newspaper or on the web you can easily copy it to this player and then solve it by hand. How does it work? The sudoku player has four modes Edit, Pencil mark, Marked and Locked. When in edit-mode you can select a digit from the number selector and tap the grid to enter that digit. You can not changed locked digits. Use the pencil mark-mode to add up to four digits to a cell. This is useful for more complex puzzles. When in marked-mode you add digits as in edit-mode but the cell gets marked with a dotted-rectangle. I use this when solving really complicated puzzles that requires guessing as a last resort. The locked-mode is used to edit the pemanent digits an only used when entering a puzzle for the first time. You can also load and save puzzles. When saving the puzzle it is packed down to a string and copied to the clipboard. Then to actually save that string you have to open a memo and paste the clipboard into that memo. To load it again, you have to first copy the string from the memo to the clipboard, open the sudoku player and tap the load button.
