The Secret Sound is the biggest competition on radio and the easiest way to win large cash prizes. The previous sound has been cracked and we have upped the stakes to a cool R20 000!

All you need to do to claim the money on offer is to correctly identify the Smile Secret Sound on-air with Bobby and Lindy.

Tune in to Smile Breakfast every weekday morning at 07:20 and 08:20 and call the studio on 0861 99 00 44 when Bobby and Lindy open the telephone lines.

The Smile Secret Sound Referee is the ONLY person who knows what the Smile Secret Sound is and will be the adjudicator every morning, telling listeners whether they are correct, or whether they are off-target and need to go back to the drawing board.

The Referee will also give Bobby and Lindy some clues from time to time, to help their listeners to crack the Smile Secret Sound.
