While not as popular as it used to be, you can still buy a Boggle game in many department stores. It is a word game based on observation and fastBrainFire thinking more than vocabulary. Attempting to quickly find words in the letters is great for training your mind to look for patterns. Once you notice an "s" for example, you can look at every noun thereafter to see if the "s" can be connected to it to create another word and more points. It is a vocabulary game in part, but decent pattern recognition skills are the best advantage you can have. http://www.healthcaresdiscussion.com/brainfire/
