With sales of HTML5-compatible phones expected to exceed one billion this year, Nickelodeon has launched a new HTML5 mobile gaming hub that will house 15 free games for iOS and Android devices.

The games, now accessible at m.nick.com/games, feature evergreen brands like SpongeBob SquarePants and Teenage Mutant Ninja Turtles. The site will be updated regularly and will be optimized for tablets later this year. Users will need an internet connection to access the mobile-friendly site.

Nickledeon is now among the few kids networks to develop games in HTML5, which reduces the need for external plugins such as Flash and is accessible in web browsers of devices such as the iPhone 4S.

The kidnet has made a significant mobile push this year, having launched its on-demand Nick App for the iPad in February.
