Words with Friends summary

A post on Zynga's blog says that resignation times are now 11 days without a move for an invite game and 5 days without a move for a random game. (Previous times were 22 days and 7 days, respectively.)

Update: Based on Iszi's comments below, I've done a little more digging and found the following information about the Android version (no idea whether this applies to the iOS version as well):

Q: Some of my games are resigning early. Why?

A: This usually means the data on your app is out of sync with our server. Again, try deleting and reinstalling the app and seeing if the resigned-early games come back.

I can now confirm from personal experience that games do not always take as long as Zynga says to resign. I started an invite game at 8:59 PM Sunday local time and made no moves; when I checked Tuesday at about 10:18 AM local time, I had lost. I have my account set to update every 5 minutes, so it seems as though in this case, my game was resigned in a little over 36 hours. (I also tried deleting and reinstalling the app, and the game did not come back.)

Was ZAP the first word played in the game? If not it had to connect to another word, and you get points for that connecting word.

ZAP should be worth 14 points. 10 for Z, 1 for A, 3 for P. With Z on a triple letter tile, you are looking at 34 points.

The other 6 points almost certainly come from the words ZAP connected to. For instance, if OUR was on the board (3 points) and ZAP was played such that the Z was on a triple letter, and the P landed in front of OUR, you would get 34 points for ZAP, and 6 points for POUR, for a total of 40 points.

Like So:
Z
A
P O U R

The full rules for scoring in Words with friends can be found here but basically, you get points for any words you create, but special tiles only get used the first time they are covered up. If your friend puts PED after ZAP, she gets 20 points, not 40.
