There are a lot of fun Spanish word games that you can play online.
Like I mentioned before, these types of Spanish games online can really help you improve your vocabulary, whether you want to be a translator or not.
Spanish vocabulary games can take the form of flash cards, crossword puzzles, or other types but no matter what method you choose, the game has to be fun so that a person enjoys playing and thus will enjoy learning.
One word game that I found online that I've recently become addicted to is a game called Wordz.
It's a Flash-based game so you'll need Macromedia's Flash player to play it, but you can easily download that from Macromedia's site.
Wordz is a cross between a wordsearch and an unscramble the letters game and it is pretty addicting so don't try it out unless you've got some time on your hands!
