Not for gambling but for their mobile phone games and experience! GLUU needs cash and ZNGA needs their experience. Huge win for both!
GLUU is going nowhere
If by experience, you mean the ability to make expensive heavily promoted games that hover around the 200-800 rank, I believe Zynga has already mastered that.
GLUU has several top games and they have a contract with MGM to make Bond games. For about $400 million, twice the market cap of GLUU, they could own them and combine their knowledge and experience.
Couldn't they just make GLUU with by killing off the Farmville Horses?
