Well, there's goes all of your mom's free time. In an open letter on their blog, Zynga announced sequels to three of the most successful games in recent memory heading to mobile platforms.

The letter titled "Thanks for playing," Zynga goes into how each game will be improved based on user feedback.

Below are some excerpts of the letter going over what's new in each game.

FarmVille, the franchise that turned 400 million of you into virtual farmers, is coming to mobile screens with the coming launch of FarmVille 2: Country Escape. The all new game builds on the rich story of FarmVille 2 by offering a Connected Rewards system between the current web game and the new mobile experience. FarmVille 2: Country Escape uniquely delivers both online and offline game play and redefines the FarmVille social experience with new Social Control options that give you more choice on how you connect with friends and family.

Poker, the game that started it all for Zynga and quickly grew to become the world’s largest Poker game, is also being completely reimagined. More than 350 million of you have played our Poker game since its launch and we have been hard at work listening to your feedback and turning it into the New Zynga Poker, a mobile-first game with more personalized gameplay, lightning fast performance and sophisticated design.

Words With Friends is the world’s favorite word game and after five years of play, you helped it become Apple App Store’s #1 free game of all time. In that time, more than 100 million of you have downloaded the game, making us a meaningful part of your lives and sharing your priceless feedback along the way. We’re proud to deliver an entirely new Words With Friends that builds on the favorite game you love but with the top features you’ve been asking for.

Zynga hasn't had a great 2013 with massive layoffs and various lawsuits. Revisiting and improving the three games that made their modest studio into a juggernaut seems like a good idea to me.
