With Google I/O 2014, Google switched to a lottery-based system for selling tickets. This means that anyone can register for a spot in the draw, but only a select number of people will get the opportunity to shell out $900 for a ticket. This, of course, means that no one is guaranteed entry into the event. It wouldn’t be Google if they didn’t throw some fun into the process. Only this time, the fun guarantees an entry into I/O.
