Ruzzle is a popular word game which arrived on Windows Phone recently. The app has just received an update to version 1.2.1 and while there is no changelog, it appears to address two very annoying issues.
In the earlier version notifications did not open the app, and players were unable to challenge their friends for a match.
WindowsPhonino reports both these issues have now been addressed.
The game costs $2.99, seemingly without a free trial, and can be found in the Windows Phone Store here.
