Sudoku for Kindle - Local Web App [aur0raHAX] [No Jailbreak]
#1  tesseractcat 07-21-2019, 01:28 AM
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. This app only worked when connected to the internet, so I didn't consider it "installed."

Recently, I discovered aur0raHAX, or more importantly, I realized it was possible to open locally stored HTML in the Kindle browser. With this, I realized it was possible to run locally stored content, similar to the "Active-content" games, via the Kindle web browser.

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. Run it by opening aur0raHAX and clicking on sudoku.html.

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 entering "file:///mnt/us/sudoku/sudoku.html" in your Kindle web browser. You can bookmark this page, and open it without internet.

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.

Such as on the Kobo Glo HD?
(Which according to your profile info. block is the only device you own.)

Sorry, I hadn't updated that in a while. Should be fixed.

The process I describe in the post should only work for the Kindle, but if there's a way to open local HTML on a Kobo Glo HD, it might work.

This is very nice, thanks, can it check a puzzle for being solved correctly or not ?

If you click "Solve" in the bottom right corner of the app, it will show you the solution. It doesn't automatically check, however.

I really wanted Sudoku on my Kindle and was even thinking of having a go at coding it myself. Can I make the following suggestions to make it more useful?

I know that seems like a lot of complaints but they're just suggestions on how to make the page more appealing and easier to use. I definitely like the idea of Sudoku on the Kindle but just found it a little frustrating as it stands. I don't think these changes would be hard to implement but would make things much easier to use.

Hello mike_bike_kite, I have addressed a number of the improvements that you have suggested. Hopefully this new version results in a better Sudoku experience. Sadly, to my knowledge, there is no other way to install this, as none of the book formats allow for Javascript, which is essential for the functionality of local web apps.

Attached is the new version of Sudoku for Kindle. If you have any other improvements to suggest, feel free to post here.

Sudoku for the Kindle is pretty cool! Especially working as an offline web app.

I myself am working on a launcher similar to aur0rahax (but fancier! (also I didn’t know about aur0rahax when I started it…)) and I was wondering if I could port your Sudoku project files to work with my launcher?

I’ll give credit and link to this topic as well

Go for it. I'm surprised Amazon still lets the browser open local html.
