Angry Birds is a surprisingly popular game with over 1 bn downloads to date.
- The popularity of the game seems to derive from deceptively sophisticated mechanics and measred timing.
- The flight arcs are unrealistically slow, but giving the user enough time to track the motion and predict the correct launching parameters for the next turn if they failed
- No time limit so the user is allowed to take their time to calculate their next go.
- Controls are very straightforward so the user doesn’t have to remember them
- The birds are flapping around and chatting quite a bit, with the data from that overwriting the memory of the target structure so as to make it more difficult to correctly hit the target
- The structure of the target building is sufficiently difficult to demolish that the user gets satisfaction from achieving it
