Play-free-online-games.com is a categorized directory of free realtime, multiplayer and graphical online games.
Games are sorted out into categories (Action, Board/Puzzle, Casino, RPG, Strategy) and alphabetical order, so it’s easier to find what you are looking for. As a user-generated content site, everybody is free to submit any game they love and want to share with other people, provided that it complies with the site’s approval criteria: that a game is free to play indefinitely (no free trials are accepted), that it allows at least two players to game at the same time over the internet, that they have a graphic interface, plus they must be realtime. At the site you will be able to find a list of more than a couple of hundred listed titles, to which a brief description and screenshot are attached, so you can check out if the game you are looking for really is the one you will be playing beforehand.
