"Hexic" and "Chess" are available to play on social networking sites Facebook and MySpace.
Microsoft's MSN Games has announced the launch of the two games for casual gamers to play online and share with friends.
"Hexic" is a "classic" puzzle game, whereas "Chess" promises a "fresh take" on the board game.
"We're excited to bring two of our most popular games to the Facebook and MySpace communities", said Megan Hodel, marketing manager for MSN Games at Microsoft.
"These networks reach more than 200 million people around the world, and the MSN Games applications will make it easier and more fun for Facebook and MySpace users to play some of their favourite casual games".
As far as Facebook goes, both games feature full Facebook integration, including notifications when badges have been awarded and games completed.
