Skate 3 is the third installment in a series of skateboarding simulators from Electronic Arts. While it has multiplayer functionality over the Internet, there is no online version of the game.
Electronic Arts still has Skate 3 available for digital download through their Origin website. Any site offering Skate 3 for free online is likely pirated, a knock-off or a delivery system for malware. A number of free online skating games can be found at skatinggames.org, agame.com and www.freeonlinegames.com. There are numerous websites that host a variety of free flash and browser-based games, but EA's Skate series has never been one of them.
