The official Google Code blog has sent out a call for all those that don’t yet have tickets to Google I/O, are developers, and still WANT tickets. Instead of just giving the remaining tickets away, however, Google has decided to launch this “Last Call for Google I/O,” a contest that will run ten days, starting on the 16th of March, one developer challenge for each of the 10 days, this contest providing 100 chances to win tickets to the completely sold-out Google I/O 2011 conference. You’ve got to go, you need to go, you love challenges, you’d better get into it, and give your fellow developers NO MERCY!

Each of these challenges will be announced on the contest site, which you can access [here], on each of the select dates at one of two times, 9am or 4pm PDT. Each of these contests will last 24 hours, each of the 10 days having 10 winners, creating again, 100 winners in total. The days and their themes are thus:

March 16 – Android, 9:00 am
March 17 – Chrome, 9:00 am
March 18 – App Engine, 9:00 am
March 21 – YouTube APIs, 9:00 am
March 22 – Game Developers, 9:00 am
March 23 – Google Maps / Geo, 4:00 pm
March 24 – Commerce, 9:00 am
March 25 – Developer Tools / GWT, 9:00 am
March 28 – Accessibility, 4:00 pm
March 29 – Google Apps / Enterprise, 4:00 pm

One of Google’s developer products will be focused on each day, each day containing then two rounds. You’ll need to be in front of your computer during the first half-hour the challenge starts, Round I, in order to be set to answer a series of questions that will then qualify you for the main coding challenge in Round II.

To qualify, you must be a citizen of the United States, one of the 50 United States that is, or of the District of Columbia. The winners will be announced on April 4, 2011. If do not win, Google asks you to remember that they’ll still be livestreaming all of the keynotes and taping sessions during Google I/O so noone has to miss the events. Full contest rules can be found on the [contest site].
