When is a game not a game? When you never win.

For years, virtualization software maker Parallels offered the chance to win a free product key if you “stump the KeyGenie,” a virtual robot which users can play against. Normally, users must buy a product key to run the software beyond its two-week free trial. But if you can make it through five questions without the robot guessing what you’re thinking, the robot says a key “may be yours.”
