This upgrade app has no application icon, it just functions as a key to disable the ads and unlock custom dictionaries in the free app.
You start the game through the icon of the free app, which you need to keep installed after buying this upgrade.
This application functions as a key to remove the ad banner from the free version of Wordplay.
Furthermore, it unlocks to ability to load your own custom dictionaries.
Note that the 3.0 version number of this app is meaningless. Getting this upgrade will work in combination with the ad-supported version, so you are always up to date with the latest features.
Again, note that this requires Wordplay to be installed as well (the actual game functionality is in that application, this application just unlocks the features).
Please note that Wordplay requires Android 2.1 or higher!!
Refer to the Wordplay description for more info about the game itself!
