Wordscraper
Wordscraper is a Scrabble-style word game available as a Facebook application. It was created by the Agarwalla brothers Rajat and Jayant, creators of Scrabulous, and differs from Scrabble by having no fixed board design or tile distribution, instead prompting the user to choose their own.
Wordscraper was reportedly released in response to a DMCA action against Scrabulous by Hasbro. It has been online since January 2008.
