History of the puzzle[edit]

Unidentified. The words "spot the difference" being used as a name for a puzzle type can be seen in a magazine from 1969 (Advertisers Weekly: Organ of British Advertising, Volume 240), according to Google Books.

The first puzzle from the first round of the first WPC (WPC 1992) was a Spot the Difference puzzle. It asked which of the images were the correct mirrored image of the sample.
