The objective of the game is to spot all the differences between the two pictures. The differences can be anything from a change in color, a missing object, a new detail, or a slight alteration in the shape or position of an element.

The number of differences can vary from a few to several, depending on the complexity of the pictures and the difficulty level of the game. Some games may have a time limit or a limited number of hints to make the challenge more engaging.

To play the game, the player needs to scrutinize the pictures carefully and pay attention to every detail. They may need to zoom in or zoom out to spot the differences more easily. Once they find a difference, they can click on it or circle it with their finger or a pen, depending on whether they are playing on a computer or a paper-based version.

Finding all the differences can be very satisfying and rewarding, as it requires concentration, observation, and problem-solving skills. The game is a fun and interactive way to improve visual perception and cognitive abilities while having a good time.
