WordFish

Install WordFish -- it will appear as a "PurpleFish" icon in the top right corner of your Chrome Browser. On any page that you visit to click the purple WordFish to FISH for words and definitions from that page (right click any of those terms to bing for a definition). Then when 4 words+Definitions are found click PLAY, and then click a [word] then it's [definition] to match up words with their definition. Hopefully you can Score:4/4!! When the game is over you can right-click a [definition] to open the wikipedia page where it was found, or click elsewhere on the screen and continue browsing.
