“Chinese whispers (or telephone in the United States) is a game played around the world, in which one person whispers a message to another, which is passed through a line of people until the last player announces the message to the entire group. Errors typically accumulate in the retellings, so the statement announced by the last player differs significantly, and often amusingly, from the one uttered by the first. Reasons for changes include anxiousness or impatience, erroneous corrections, and that some players may deliberately alter what is being said to guarantee a changed message by the end of the line.

The game is often played by children as a party game or in the playground. It is often invoked as a metaphor for cumulative error, especially the inaccuracies as rumours or gossip spread,[2] or, more generally, for the unreliability of human recollection or even oral traditions.” (Wiki)
