Does anyone know of any muliplayer games that are web based? I was hoping to challenge my colleagues in the office during lunch break on something but can't find anything suitable that is 1 PC vs 1PC

Obviously I'm hoping to find something that doesn't need installing on the works machine.

Any ideas would be welcome.

It would also be interesting what you guys play during dinner. Lightning Pool or Asteroids are my top games

There's Yahoo Games

Scrabble, Pool, Backgammon, & stacks more.

HTH
