Why Angry Birds is so successful and popular: a cognitive teardown of the user experience:

"Mystery is that second layer of attributes that are present but undefined explicitly, yet somehow created with just enough context to consume mental resources in subtle and compelling ways. At its most basic level, experiencing mystery in what we interact with makes you ask the question, “Why did they do that?”. What we mean here is, “Why did they do that? – A good thing, not “What were they thinking? – A bad thing. If you think carefully about the experiences you have in the ebb and flow of life, you realize that the most compelling are those that force you to think long and hard about why a given thing is the way it is. For example, why did Frank Gehry create the Guggenheim Museum Bilboa using the shapes he did? The famous architect could have created any shape concept, but why did he choose those shapes? It’s a mystery – we do not know and probably neither does he. What we do know is that his creation is cited as one of the most important works of contemporary architecture. In the same way that a building can captivate millions of sightseers, the element of mystery (conceptual depth) can help sell a few million copies of a simple interactive game."
