Guess-the-Google
One entertaining game that can easily waste an hour of your day is Guess the Google. Head over to the site and click "Launch Project" to play.
In Guess the Google, you play 20 rounds. In each round, 20 pictures appear. What they have in common is that they are the results for a Google Image search on a particular word. You have 20 seconds to guess that word. You get a bonus point for each unused second left after you guess the word.
This is a fun little game. I've come back to it a few times and still enjoy it. Perhaps in a couple weeks I will post about a similar set of Google-based games that require two-player competitive/collaborative efforts.
