At Kongregate we're building the leading site to play games - or to make them. We have thousands and thousands of the best free games, and our community features mean that playing them here is more satisfying than anywhere else. If you do well in our games you'll earn badges, level up, and gain the respect of your friends. Profiles, chat, comments, private messages, and forums make it easy to exchange game tips or just relax in the company of enthusiastic gamers from around the world.
We know that making great games isn't easy and our mission is to help indie developers make better games and earn more money doing it. We share advertising and microtransaction revenue with game developers - and they retain full rights to their games. With features like multiplayer support, persistent data storage, high scores, and statistics, we take care of a lot of the headaches involved in game development.
