 **What is Boggle® and why are we writing it?**
 
- Duke CS used Boggle® for a Compsci 308 assignment at Duke in 1996. Boggle is in the [Nifty Assignments Archive] (http://nifty.stanford.edu/) and the current instantiation of the assignment is a combination of efforts from Compsci educators at Duke, Stanford, and UCSD. This version emphasizes empirical analyses of tradeoffs in different implementations.
-The [Wikipedia Boggle] (http://en.wikipedia.org/wiki/Boggle) entry explains the game in detail including popular culture references to Boggle. Reviewing the rules on the Wikipedia site will help in understanding the play-of-the-game, but you'll be looking at implementation trade-offs that are independent of game-playing. You can play games based on words that are similar to Boggle online, e.g., Facebook's Scramble and Yahoo! Word Racer both of which are definitely related to Boggle.

 Analyzing alternative implementations and algorithms will help inform a better understanding of both work and play, what a great way to build a foundation in understanding how to turn data into information.
