My list of free online games with prizes

I'd going to post a little review on free online games with prizes. Haven't done the job yet so I'm just posting a couple of sites - maybe you could participate?

I mean, is anywhere a site where i can play online FREE games and win lots of prizes?
If you know such a site, drop me a line - pleeeeese!

1) This one is pretty cool - Receive $5 just for joining InboxDollars - they pay members to play games, etc. Membership is free. It was mentioned on Good Morning America - have you heard that ad?

2) Another favorite of mine is Gamevance Online Game Tournaments.
I tried all of their 25 games online and I believe that my scores are pretty high -
last month they rewarded their top 200 players with iPods, $200 Visa Giftcard ( I SURE could use it ! Gimme some MORE!!!)
Playstations and Motorola Rokr (cool...could have find use of this, too %#@).

3) Backgammon - they run Live Tournaments for Fun OR Money - the last is of most interest to me you know.

I have a couple more sites to share but I've been testing these now, will add some feedback in a week (I think).
