找不同（又称找茬、找别扭）是一种智力游戏，玩家需要在指定的时间内找出两幅相似图片中的不同之处。最初的找不同游戏出现在纸质图片上（如报纸或儿童书），后来也衍生出了很多电子游戏版本。

Spot the difference is a type of puzzle where players must find a set number of differences between two otherwise similar images, whether they are illustrations or photographs that have been altered with photo manipulation. Spot the difference games are also known as photo hunt games, and are commonly found in activity books for children or in newspapers.
