Sega has launched, a new online portal for casual games which will target "all types of gaming and social networking fans".

The site will offer a number of titles for free, including arcade classics, word, puzzle, quiz and sports games, as well as a couple of Sonic titles.

You'll be able to compare your high scores against other players, and the more you play, the more you'll be rewarded with PlaySega Rings. These act as a form of currency that allow you to create your own "Escape Area" customised space.

As well as the free games, there will be more premium games available for a charge from PlaySega VIP.

"What started off as a small project within the Sega Network Group has now caught the imagination of the entire company", said Nick Pili, Network business director at Sega Europe.

"I have suggestions for new games filling up my in-box, from the CEO, to staff I've never even met over in our Japanese, European and US offices".

He added: "Sega fans and new gamers alike can now come together in one place and enjoy some of our most exciting vintage and new titles".
