Okay, I finally got some REALLY good info. The older scoring system is back in effect and the points for words have been changed.
Easy, Medium, and Hard words are 1, 2, and 3 points each.
Finishing all your words (thus ending the round) gives you 1 point.
All other players will still dump their tiles for unfinished words.
Extra points are awarded at the end of the game once again:
2 for most Easy words finished, 3 for most Medium, and 4 for most Difficult. (Needs testing)
