News Talk 960 WSBT encourages listeners to play the contests we often air weekdays between 5:30AM and 7PM. These are the guidelines: Contests are open to legal U.S. residents 18 and over.  One winner per household every 30 days.  Employees of WSBT, Inc. and other radio stations not eligible.  The announcer will designate a certain number caller. If that caller to 282-2696 does not have the correct answer, the next caller with the correct answer will win. If no winner is declared, no prize will be awarded.  Ties settled with a random drawing.  WSBT cannot be responsible for disconnects or telephone difficulties.  Selected contests may have specific rules.  A complete listing of rules is available at 300 West Jefferson in South Bend during regular business hours.
