Since the “Catch a Game” promos started, you may have noticed every now and then a plug for GSN Radio.  If you went to the Radio page any time before this week, you either got a “page did not exist” or a “coming soon” message.  Well, we finally have a premiere: August 18 (this Monday).  Starting at 1:00 EST, GSN will have four straight hours of games streaming online.  Bob Goen and Marianne Curan will host contests and games such as “The Birthday Game” and “Secret Sound?”.  You can sign up now online or you can call 1-877-7-GSN-RADIO Monday morning.  You must have “caught” 21 to play (as in, you must be 21 or older).
