A secret decoder ring (or secret decoder) is a device which allows one to decode a simple substitution cipher - or to encrypt a message by working in the opposite direction.
As inexpensive toys, they have been often used as promotional items by retailers, radio and television programs from the 1930s through to the current day. Decoders, whether badges or rings, are a fun way for children to tap into a common fascination with encryption, ciphers, and secret codes, and are used to send hidden messages back and forth to one another.

Famous quotes containing the words ring and/or secret:
“Time has no divisions to mark its passage, there is never a thunderstorm or blare of trumpets to announce the beginning of a new month or year. Even when a new century begins it is only we mortals who ring bells and fire off pistols.”
—Thomas Mann (18751955)
“Melancholy is at the bottom of everything, just as at the end of all rivers is the sea. Can it be otherwise in a world where nothing lasts, where all that we have loved or shall love must die? Is death, then, the secret of life? The gloom of an eternal mourning enwraps, more or less closely, every serious and thoughtful soul, as night enwraps the universe.”
—Henri-Frédéric Amiel (18211881)
