Copy or Not Copy puts a twist on the familiar "spot the differences" challenge as now you're trying to find the original image from which all other images differ.

In the game, all players are presented with a card that shows four or five images on it. One of those images is the original source, while all of the other images differ from that source in one way (and thus in two ways for each other). The first player to spot the original image claims the card, and whoever collects the most cards wins!
