Many Electronic Arts games appear to be on sale today. It’s looking like an Easter sale, up to 80% off, so it may be throughout the weekend; no promises though… 
Scrabble $2.99
I only own a few: Scrabble is awesome (and lets you play over the Internet via Facebook) I did a review here, Boggle, Lemonade Tycoon and Sim City are all pretty good. Do you play any of the EA games?
* These are affiliate links, so I get a (very) small kickback if you buy one of these. But it is a really good deal on some of these games.
I play “Words With Friends” on the iPhone. It’s just like Scrabble and is a fantastic app.
