Sudoku Solver for iPhone

Released 30th April 2012
Update released!
Now in the AppStore

Apple have approved and released the new SudokuWiki Solver App for the iPhone/iPod touch.
Now available for purchase. We have changed to the Tier 2 price band.
There will be major updates to the solver as we include more puzzle variants and solving strategies and these will be free revisions to any purchase. We also intend to make a 'universal' App when the iPad version is complete - one purchase for both platforms. We're extremely pleased with the final build and I hope you'll be impressed as well.

Do give us your Feedback Form - especially new ideas - on this page or on the Apple Store.
Our App Support Page is here. We'll post updates to this page.

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.
Strategy Guides
Included are all the strategy documentation found on this site and each example can be loaded into the solver at a click.
Puzzle Feed
The Daily and Weekly puzzles on this site are now automatically downloaded into the App!
Camera Input
We're very pleased to include a camera input directly from the App. Click, check and load into the solver.
Favourites
Keep track of the puzzles you solve with an almost limitless list entry - each nameable.
Hints
New to our solver - Instead of just "Take Step" use "Hint" to give you the strategy to look for without revealing the answers.
Resume / Back
Better than the website with real 'state' saving - quit and resume any time. Also a start to end 'back' button.
Email and Facebook
Send to your friends via Email or Facebook. Links back to the solver enable easy loading of shared puzzles.

The SudokuWiki Solver App has all the cell and candidate highlighting used on the website version. Here and XY-Chain is found.
Note: Screen shots have been shrunk by half

Next build - released!

  • We have added an automatic download of the four Daily Sudoku puzzles (one of each grade) plus the Sunday Extreme Sudoku AND the weekly Unsolvable. These will be stored in the list of available puzzles for easy loading. This website allows you to play one of the four Daily Sudoku - the other three are available through syndication and on the 5 Daily Puzzles app.

Next build and Version 2



  • Our immediate plan after release of version 1 will be to create an iPad version of this solver. With the iPhone version done it is 90% ready. We just need to take advantage of the great space afforded by the iPad
  • Concurrent with the iPad version will be the first build of the Android version.
  • Version 2 will start to include Solvers for other variants, to be added in this order: Sudoku X (because it's the easiest), Killer Sudoku, Jigsaw Sudoku, Colour Sudoku.
  • On our wish list for version 2 - add a Sudoku 'Player' with a feed from this website so you can solve the Daily Sudoku puzzles - and if you get stuck, carry them over to the solver.
  • From recent feedback we know that your wish list includes a 'hint' system. This will enable you to use the solver as a player and the "take step" would suggest a strategy at any stage. This is a very interesting feature and I will prototype it on the website solver first. - this is now in the released version!
  • Various Sizes will also be considered: 6x6 and 8x8

If you want to add something to this list or make a point about how the solver should work, please let me know, either write to me at andrew@str8ts.com, or use the Feedback or leave a comment or Facebook comment here on this page.

All ideas welcome

best regards

Andrew Stuart and Oliver Foggin

No update since a very long time for iOS. What a pity.

Is the Sudoku wiki in the app store compatible with the ipad or are you releasing a different app for the ipad. The documentation is a bit confusing.
Many Thanks
Mal

Hi,

I've just seen android pictures version and it seems that it got a better interface than iOS version. Have you planed to make an update for iOS?
Android version got options that iOS version don't have. Please update iOS version. Thank you.
And what about iPad version ?

Andrew -

Any update on when the iPad version will be ready?

I love the app on the iPhone but am looking forward to the iPad version taking advantage of the larger screen size.

Merry Christmas and Happy New Year to you and yours.

Hi Andrew,
Thank you for your answer and for this great Sudoku Wiki.
It's amazing to have your solver on my iPhone and solve sudoku anywhere.
I've made a revue on the apple store and I have a request for your next update.

It would be great to have an option to auto create a grid according to the number of clues and grade.

Thank you again and go on that way ;-)
By the way the price is very fine. Less expensive than other sudoku and more efficient than others.

Best Regards, Frederic

Thanks Frederic
On your suggestion we've posted an updated version which has the better grabbing of a sudoku string in any amount of clipboard text. No sure what the approval time will be, could be one day or a week.
Cheers

Hi,
What a very good news and thank you for screenshots.

Is the iPad version will be universal?
If we pay for iPhone, will we be able to update for iPad version ?

Regards, Frederic

The OCR feature sounds cool. You might want to contact the guy who wrote 'AR sudoku solver', he already tackled the problem.

I have been a huge fan of this solver for a few years. The way the steps are constructed for checking are excellent and educational for process. I am also excited to see an iPad version as it is tedious to enter numbers. As a "non-expert" I'd love to get more of a beginners explanation of some of the more advanced solving techniques. Specifically, how to spot when to use these techniques and maybe a "here's one for you to try" example once one has a good idea of how to use each one.

Re: Anthony Shortland's suggestion for the "dot" method - Wow! Someone else who uses dots - I thought I was the only one! Invaluable in those printed puzzles in the newspaper that don't have enough space to write the candidate numbers - so I imagine similarly useful on small phone screens.

Andrew - maybe each cell could actually be programmed with 9 sub-cells. Select the cell then hit a number to put a number in that cell. Select a cell, then a sub-cell to put a candidate in. May need a pen type manual pointing device for user accuracy, or sharp fingernails! ;-)

Hi Andrew.
I discovered your solver for a long time now and the idea to see this solver on iPhone, well, what a very good thing. I played a lot of sudoku for mobile phone but none of them had the same functionnalities.
I saw that you were looking for beta tester and I would be very proud to be one of them.
Best regard.

This is the first time I have viewed your site and I am highly impressed with your solvers. I wouldn't hesitate to pay a premium (15-20 bucks) for a mobile app (preferably Android) that has a similar functionality to what is on the site. I love how the "yes" and "no" show up on the "strategies." Amazing...!

I'd like to suggest you include the "dot" method of marking candidates in each square as a cleaner way to present a partially solved puzzle.

i.e. simply place a dot in each of nine spots in each square to indicate the candidates.

I'll certainly put this idea on our wish list.

Glad to hear you're working on an iOS app. Would really like to be A beta tester!

Hi,
What a good news to create a solver on iPhone. There are few sudoku solvers really interesting on iPhone.
But !!!
What do Robert and Eric expect from you to tell you that they could pay $20 or more for this solver.
In my opinion, I think that's very ridiculous and scandalous. You never talk about money so why do they talk about money for you ???
Once again, ridiculous;
Have a nice day...

Hi. It won't be that much, don't worry! It will be in the first or second price band. :)

Great plan. I've been hoping for a solver for my PC, but for my iphone would be even better. I also like the ideas of being able to highlight cells with a specific number or highlight cells with only pairs. Additionally using another highlight to mark links is good. The Sudoku program for the PC that does a good job is by sadman software. Nothing is has your suggested list of features for the iphone. I'd also pay $10 to 20 for the top tier feature set.

Hi Andrew.
Really happy to read this post. I don't know if you remember me but I've already wrote to you if you could make a java version for window of your solver and you answered me that you couldn't cause the only program you were using was your in-line program or so. And now I can see that you are working on iPhone version and I'm so happy. Thanks a lot and I really look forward to see your APP on the app store.
By the way, I think that the price below $5 will be a good idea. I don't know if Eric G. was serious but $20 was really too expensive.

Sorry for my poor English but I'm French so be indulgent ;-)

Hi Andrew,

Although, Enjoy Sudoku is giving you a run for its money, i certainly think there will be a market for the program you have suggested. Maybe i missed it but, if you can generate sudoku puzzles as well it would be great. I would suggest that the routing stuff you have on the internet showing strong and weak links be available and more importantly that we the user be able to draw our own links in a user friendly fashion. Furthermore, as at very high level us sudoku fans are pretty hardcore, don't be shy to charge a premium... I would have no problem paying $20 or even more for the program. You could perhaps have tiered amounts depending on the level of functionality. I am excited you will finally join the bandwagon and Iam highly confident you will regain your title of leader in the mobile world as well. i would be delighted to beta test if I can be of any help

Glad you like the idea and thanks for the ideas. It will probably be in the 2nd or third price band. Above 99c but below $5. Haven’t thought about that yet. I’ll add you to the list for beta testing, appreciated.

Drawing links – that would be a nice idea.

Generator slightly more difficult. Random and throw away, one at a time sort of thing?

I was sitting here using your web page to help me with a sticky Sudoku puzzle and I said to myself 'gee, i wish this was an app for my smart phone'. I then noticed at the top of the page your note about creating the app. YAAAY!

I really look forward to using this app once you have created it for the Android. I think the features you have incorporated on your website will make this the premier app for playing (and learning to play) Sudoku.

Every other Sudoku app I have tried has made me think 'gee, i wish this app had features like the Sudokuwiki.org site.' Now I wont have to think that anymore.

Thanks for making this app! I look forward to it.
