Support for iOS Versions
The first place to look for help is in the manual. Press the "Learn" button on the main menu to find all kinds of useful information, both about Sudoku and using the app.
:) Sudoku + crashes under iOS 10? - You need to update to the most recent version. There is a known incompatibility between older versions of :) Sudoku + and iOS 10. This is fixed in the most recent version.
All of the digits disappear occasionally in Wild & Weird style? - You need to update to the most recent version. There is a known incompatibility between older versions of our apps and iOS 10. This is fixed in the most recent version.
Having problems? - The first thing to try is to be sure you are running the most recent version. Check for application updates in the App Store or in iTunes to see if a more recent version is available.
Scan from camera just shows a black screen? - Under iOS 8 and newer, you need to give permission to the app for it to be able to access the camera. In Apple's Settings app pick Privacy and then Camera, find the app and make sure it is turned on.
:) Sudoku should offer more puzzles each day - Purchase our paid version, :) Sudoku +, or try our free ad supported version, Sudoku Joy, to be able to play unlimited games.
Why don't you do ________? - We constantly get feature requests for features we already have. You should look at the settings page. There probably already is a setting to do what you want. If we overlooked some feature, feel free to send us feedback asking for it.
I found a puzzle with no solution or two solutions? - Every puzzle in Enjoy Sudoku is a valid Sudoku puzzle with a single solution that can be determined with logic alone. People often tell us that they found a puzzle with no solution or two solutions. However, when they send us a screenshot of the puzzle, it invariably turns out that they have made a mistake somewhere and the puzzle has exactly one solution.
If you get to a point where you think the puzzle has no solution, double check your existing entries carefully. It's fairly common to accidentally enter an incorrect digit early on in the solving process, and not notice a problem until much later. If you can't see the problem you can use Check Entries or ask for a hint, either of which will normally tell you where you've made a mistake.
If there aren't any mistakes, you can use "Show Solution", on the hint menu, to see the solution to the puzzle. Alternatively, you can step through the solving steps using hints to see the full logical sequence.
Another very common mistake is an incorrect identification of a deadly rectangle which appears to indicate that the puzzle has two solutions. Remember, a deadly rectangle must have cells in only two blocks and none of the cells can be clues. If you cannot figure out what's going on, get a screenshot of the puzzle and send it to us.
My device was replaced or reset and I can't find your app? - As long as you are using an iOS device and have the same iTunes store account, you can download a fresh copy for free. Launch the app store, pick the Purchased tab (or the Updates tab and then select Purchased), search for :) Sudoku +, and press the cloud-with-down-arrow icon.
When all else fails, you can contact tech support via email.
