I was reading the November 2008 issue of Discover Magazine. I really enjoy this magazine and find it quite interesting, even though many of the concepts they discuss are far beyond my level of education.

Discover has a section titled “Mind Games” where thy list various puzzles etc. This month they focused on the relatively new number puzzle “Hidato”. The idea is to connect all the given numbers with consecutive numbers. Numbers must be adjacent to each other connecting either vertically, diagonally, or horizontally.

One of their puzzles provided this example, and asked how many possible locations are there for the missing #16.
