Why have the generate options (easy to hard) on screen all time - better to have a settings button where the user picks the level they like to play at then just have 2 buttons for New and Settings.The method of adding multiple optional numbers to a square is quite confusing - maybe better to have a "mode" choice under the digits where you can either chose to place a final number (that clears the options) or add an optional number.You can currently have optional numbers showing in a square as well as a final chosen number - this is wrong.You should just have an empty square alongside the choice of numbers. There should be a way to clear a number! when I worked out how to add a number to the screen I just added one at random and then found I couldn't remove it.
I found it confusing having the title flicking in and out with the number options - it would be better if the number options remained permanently on screen once you start a puzzle.That should be easy to fix via table formatting or CSS. I assume the same thing happens for rows.
If a column doesn't start with any numbers then the column is currently compressed - there should be a fixed size for squares. Can I make the following suggestions to make it more useful? I really wanted Sudoku on my Kindle and was even thinking of having a go at coding it myself. This was tested to work on my Kindle Voyage, running firmware version 5.9.6.1, I cannot ensure that it will work on any future firmware versions, or any other devices. You can bookmark this page, and open it without internet. Run it by entering "file:///mnt/us/sudoku/sudoku.html" in your Kindle web browser. To install Sudoku for Kindle without aur0raHAX, extract the attached sudoku.zip, and copy the sudoku folder to the root of your Kindle drive. Run it by opening aur0raHAX and clicking on sudoku.html. To install Sudoku for Kindle with aur0raHAX, extract the attached sudoku.zip, and copy the sudoku.html and sudoku.js files into the "Apps" folder inside your aur0raHAX installation. With this, I realized it was possible to run locally stored content, similar to the "Active-content" games, via the Kindle web browser. Recently, I discovered aur0raHAX, or more importantly, I realized it was possible to open locally stored HTML in the Kindle browser. This app only worked when connected to the internet, so I didn't consider it "installed." After someone inquired in a thread about whether or not it was possible to install a Sudoku app on a non jailbroken Kindle, I was inspired to create an online, Kindle themed Sudoku app.
