Online skill games company King.com released its first series of titles designed exclusively for social networks -- Kalorie King and Mars Lives -- to Facebook. The studio also announced Amazon Survival for iPhone.

The titles join over 150 other skill and social games that King.com offers to more than 17.6 million unique users per month. Launched in 2004, the company is the exclusive provider of skill games for portals and sites such as Yahoo!, MSN, AOL, NBC, and more.

In Kalorie King, players try to burn to burn as many calories as they can and increase their score by catching falling vegetables, fruits, and vitamins. They can challenge friends to weight loss tournaments, find out who can burn the most calories the fastest, and share their scores on their Facbook newsfeed.

Mars Lives is a massively multiplayer and episodic game about the first human settlers on the red planet and the challenges they face with colonizing the new world.
