Zynga and Facebook changed their developer agreement in November 2012, allowing Facebook to develop its own games.
The move also permits Zynga to no longer feature Facebook ads or offer Facebook credits as a form of payment.
The social gaming site has kept many of the same features but now allows users to create a seperate Zynga account.
"We hope you enjoy what we believe is a natural evolution of Zynga.com, said Cadir Lee, Zynga’s chief technology officer. "We’ve kept a lot of the great features like live Social Stream, Fast Load and Online Presence which lets you see who else is playing right now.
"Some of your favorite games will be on the new site at launch and we will continue to work hard to bring you more great games and new features over the coming weeks and months."
The new signup will be available next week but Zynga will still allow users to connect with Facebook.

"We also wanted to make sure that existing Zynga.com players continue to have the best experience possible so you don’t have to start from scratch," added Lee.
"All players will have the option to connect with Facebook and keep your game friends and game progress, while deciding what you share with your gaming community."
Lee said the company is also working on plans to connect gamers to other sites such as Gmail and Yahoo.
Last year, Zynga cut 11 games on Facebook as part of its planned shutdown of 13 game titles to create a more stringent budget.
Zynga was founded in 2007 and gained new users in its starting years by using Facebook’s network to increase profits and sales.
In 2011, Zynga was responsible for 12% of Facebook revenues and announced in early 2013 that it’s game, ‘Farmville’ reached $1bn in total player bookings.
