Sudoku Solver and Grader
This App contains the full 9x9 Sudoku Solver as seen on this website.
This includes the Grading feature and Solution Counter.
364 Practice Puzzles
Expanded Samples List: now organized into groups that focus on a specific strategy.
Smartphone to Tablet
Four different layouts have been designed to match the many different Android screen sizes and pixel densities
from Smartphones (minimum 480x800) to tablets (1280x800).
Included are all the strategy documentation found on this site and
each example can be loaded into the solver at a click.
The Daily and Weekly puzzles on this site are now automatically downloaded
into the App!
The solver board can be set to several color schemes including high contrast colors.
Keep track of the puzzles you solve with an almost
limitless list entry - each nameable.
New to our solver - Instead of just "Take Step" use "Hint" to give you the strategy to look for without revealing the whole answer.
Better than the website with real 'state' saving - quit, resume any time and a start to end 'back' and 'forward' buttons.

Access to the main features from the home page
Note: Screen shots have been taken from a 480x800 device and shrunk by half. Other devices may have higher screen resolutions and marginally different layouts.
Feedback and Wish-List
You feedback will be most welcome. If you have an idea for a new feature or improvement, don't be shy. Often these can be implemented very quickly. Bugs and other issues most gratefully received.
I am not 100% certain the different layouts groups I've designed will perfectly match all screen densities and resolutions. If you think the solver page or main page looks a little odd - either clipping or too much padding - please let me know. I can add more layouts. Please include the screen information found at the end of the Preferences screen.
Practice Puzzles - puzzles that contain specific strategies
A future upgrade will contain the Sudoku X and Jigsaw Sudoku puzzles - complete step-by-step solvers including grading and solution count. There will be an editor for entering Jigsaw patterns not found on this site or in my puzzles.
I will explore Camera Capture. This is the only major feature present in the iPhone version that's not in this app. Something I'd like to do but it will require a lot of research.
The 'hint' system could use some more work. I prefer the three levels of hints in the iPhone version and I'll be working towards this in later versions. Currently the hint system reveals the strategy used and colors some cells and candidates, but not the eliminations. This can be too much for some strategies and too little for others.Two levels of hints are now in the App
The app has the ability to call and email program with a link to the website solver and the current puzzle. I'd like to do more and add some kind of Facebook connectivity.
