The what, why, and how of Angry Birds

For our final game, we are looking at Angry Birds; for some, this will have been a staple game in your library since its launch in 2009. But just in case you have lived under a rock for the last few years, let's have a quick rundown on the game.

Angry Birds was first released on iPhones back in 2009, created by a company called Rovio. With around 2 billion downloads, it is one of the most popular games ever created.

From a gameplay perspective, the aim of the game is for the player to slingshot a bird, a very angry bird, into the enemy pigs' fortress. The idea is to eliminate all the pigs before the player runs out of birds to fling across the screen. The game mixes this action with a puzzle element as each fortress is differently designed with differing materials that require different attack tactics, and also there are different types of birds with different abilities that can be selected. Let's take a look at the following image:
