Here is one for those of you who like backgammon. You only play the "computer" but this site tracks your score for you. You can also check other people's scores to see how you stack up! This is a JAVA script that is rather long so it takes a few for it to load (if on dial-up), so be patient.

This is a rather interesting game of Russian Roulette. the neat part is that the losers browser shuts down! (Not permanently....lol)

Here is one called The Box Game. This is a good one that is easy to learn, but hard to master.
