Free Online Games (F.O.G.) so just type in fog in Google and it will be the first result and has tons of games and is basically the same thing as addicting games but with different games.
Onemorelevel.com has a lot. Plus it has some retro games like pacman, Mario, etc. that sometimes other website don't have.
Kongregate, I think it's the best one ^_^ it's free too!
Oyunlar1.com/index.asp and funbrain
Miniclip, gamesloth :)
