In chess, there’s something known as a “[a knight’s tour](http://en.wikipedia.org/wiki/Knight%27s%5Ftour?ref=killscreen.com).” It’s a sequence of moves around the board where the knight visits every square only once and the problem has been a challenge for mathematicians to solve it since Swiss physicist [Leonhard Euler](http://en.wikipedia.org/wiki/Leonhard%5FEuler?ref=killscreen.com) tackled it the 18th century.

If you didn’t know, that’s ok. There’s some nice shorthand of the problem in the form of *BoxPop* [the new iOS titled released by FreshPlanet last week](https://itunes.apple.com/us/app/boxpop/id895127924?ref=killscreen.com). The gameplay follows the knight’s tour problem to the letter (L, of course) as you must remove all of the titles on the board by following a knight’s movement.

AT&T has researched that are [more than 13 trillion possible knight’s tours on a chessboard](http://www.chess.com/blog/kurtgodden/a-tour-of-the-knights-tour?ref=killscreen.com). Fortunately, *BoxPop* only features 40 levels for you to start with.
