CLAY.IO

Clay.io is a platform for HTML5 games. The first service provided is a [marketplace](http://clay.io/play) for cross-platform games. Clay.io takes the fragmented market of HTML5 games and brings it all together in one place. Part of this includes tying all achievements earned, high scores achieved, and screenshots taken, regardless of the device, all to a single user account. In addition to the marketplace and user accounts, Clay.io provides developers with [high-level tools](http://clay.io/development-tools) like payment processing, leaderboards, achievements, user accounts, analytics, and much more.
