One of the best sites to play Flash games. If you are a developer and post a game they give you up to 50% of the ad revenue on your game's page. The minimum for this is 30%, so you'll still get some money. Also has great AS2 tutorials for making a game. And, I never got any viruses from it and I've been using this site for years.
Awesome game site! completley safe I have used this site for over 2 years never a single pop up. No bad ads, they protect your privacy. This is the best flash game site I have ever came across. It does save cookies and temporary internet files for save games of course, but everythings 100 percent safe from my experiences :)
