On iOS, Android and Kindle devices you are able to complete Crosswords and Sudokus directly within the app.
To start solving these please follow the steps below:
1) Open the magazine and page where the puzzle is displayed
2) Press on the square you wish to fill in (you may need to press and hold down for 1 or 2 seconds for the fill option to appear)
3) A keyboard should then appear and you will be able to complete the puzzle :)
Note: If you cannot complete the puzzles properly it might be because your device does not have the standard keyboard software - in this case, you might want to revert it back to normal so you can complete the puzzles.
