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.

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
