Previously, there was a 'lite version' and now, it is the whole enchilada... and FREE, with advertisements, however, there will be a paid option to remove these soon.
The demand for the game was so strong that within a short time, the game hit 100,000 downloads right after the announcement, but you can easily grab the game now, directly from the android market.
I am NOT a video game player, despite my years, bringing Newgrounds.com to the masses but LOVE this game... and WordFeud.
