Finding the differences is always about two major things: a high degree of attentiveness and the ability to spend enough time to find them in pictures (a.k.a. perseverance). In the online differences games to play for free, a gamer is usually offered to find the differences between two or amongst several pictures, marking them with finger tapping or mouse clicking. After all the differences are found, the level of a differences online game is considered passed successfully and a player is offered to pass another one. Some simple enough games of this category only have one level in the entire game; others have many, around 10 or between 10 and 100. So, depending on how hard it is to find the discrepancies in the pictures and the number of levels, every game of that kind is passable within a different time — that can be minutes or hours.

So, you will very unlikely be facing a situation, where you just can’t find all the discrepancies. But even if you do, many games have an option of giving a hint, which simplifies the gaming process and makes you immediately show progress.
