12 Reasons Angry Birds Is So Successful & Popular

Games that are easier to learn are more likely to become popular. Angry birds can be learned in seconds with almost no instructions no matter what the age of the player is. This led to wide adoption of the game across different age ranges (See why simplicity leads to popularity).

Most games use frustration to keep people hooked. For example Tetris keeps people playing by always introducing shapes that make their structure uneven. Angry birds frustrates users in seconds by displaying the annoying pigs (See why Frustration is important in gaming).

Angry birds is one of the games that allows the release of anger and tension in a subtle way. So many people unconsciously feel like playing the game when they experience a little bit of anger that needs to be released. By smashing structures and killing pigs, people can get a quick relief.

The characters of angry birds look very interesting to the extent that the franchise extended to include cartoons and toys. People get emotional, no matter how rational they seem to be and interesting looking characters always intensify the emotional connection to a game.

The pigs were designed to frustrate players and make them eager to kill them. The fact that it's not always easy to kill the pigs makes the game even more frustrating. This frustration keep people playing and easily addicts them.

Games that have novel elements are more likely to catch attention since the human mind filters noise and repetition. The characters of the game are very novel, yes they are birds but they don't have a body. They have big eyes and interesting looking faces (See why Novel things appeal to us).

The game is very simple to learn but very hard to master. A combination that has made so many games, such as Flappy bird, instantly addictive. People learn fast, but keep playing for long periods of time because they can't completely master the game.

With each level, the complexity is increased and this keeps people hooked. Had the game started with a higher level of complexity it might have not have been that successful.

A few seconds pass after the bird flies in the air and before the next game starts. While a short response time is usually better, the response time in angry birds helps people rethink their strategies and adjust it in the next attempt.

Because Players are only allowed to see the structure holding the pigs for seconds before the screen moves, the short term memory of the player is usually wiped fast and the player finds it harder to aim at the right place. The sounds the birds make helps distract the player even more.

When a player misses the pigs, their annoying images are displayed while they make very annoying sounds. These sounds frustrate the players even more and motivates them to restart the level and kill the pigs (See the importance of rewards in Game design).

The game has bright and interesting colors. Kids find those colors appealing while adults find them soothing as they allow them to escape from the real stressful world.
