Facebook Scrabble
Two official versions of Scrabble are available on Facebook, one for residents of the U.S. and Canada and the other for residents of other countries. A third Scrabble-like game, Lexulous, is also available. (Lexulous was known as Scrabulous until lawsuits were filed against the creators by both Hasbro and Mattel.) Free registration is required to join Facebook. To play without ads, you must pay a fee. An ad loads after every turn if you don’t pay for the ad-free version. You are able to compete against your friends, track your Scrabble ELO rating, customize your board and tiles, and pick up gameplay where you left off on your smartphone or tablet. You can also play against a random opponent or turn on speed play.
Facebook Words with Friends
You can also play Words with Friends on Facebook, powered by Zynga. You can start a game and notify a Facebook friend, or let the game match you up with someone.

In addition to being available at Facebook, Lexulous can be played at Lexulous.com. You can join a room to play with other players or elect to play a robot. There is also an option where you can watch other players play and learn their strategies. Free registration is required to join Lexulous.com. You can join using your Facebook profile if you prefer.
