WordHaste for Windows Phone 7
Wordhaste is a new, addictive word game that is played live against other players on the Internet. Players use letter tiles to form words horizontally and vertically across the board (much like in Scrabble). Whoever scores the most points in a given round (which lasts 2.5 minutes) win the game.
Each round, the letters generated will be different. However, each player works off the exact same set of tiles as the other players during a given round. After the round is completed, you can review the words you found and see the leaderboard to find out how your score compared to others.
Wordhaste is free and can be downloaded here.
