CAGiversary!
Not sure if it belongs in the free section on here but either way it's a game that is free. It's a pretty much a browser version of the game Boogle. You can sign in with your Xbox Live account and earn achievements as well. If you played any other versions such as the Windows Phone Version or the iOS version some achievements will unlock immediately from the go for those we like to earn achievements. Anyhow enjoy it's a fun little game to pass the time.
