WordSquared is a massively multiplayer online scrabble crossword that uses MongoDB to store location data. Players place tiles in realtime, and compete to build the longest chain of words and earn points. WordSquared leverages MongoDB's built-in geospatial indexing, storing an x and y coordinate with each tile and using bounding box queries to
display a view of the board.
This presentation covers the architecture of the game, with a specific focus on the use of MongoDB, storing and querying location data, and learning how to structure and even shard geo data through the unlikely use
case of an infinitely large board game.
