It's been a great year, with some great contests - now let's make the last one the best!

We've had a blast running developer contests this year, so let's finish it with a bang. Not a 'something just broke' bang, but a 'this is amazing' bang.

To do that, we are adding a bit more time. This contest will run until the end of the year, almost twice the time of our past contests. And, as expected, there is a ridiculously cool prize pack. 

How does a littleBits Smart Home kit, Chromebook Flip, and an RC Helicopter sound? Like a big pile of fun? Yeah, that's what we thought too. So how do you win? Well, prove your project is just as awesome as that set of prizes.

littleBits takes individual components and lets you combine them in interesting ways. So build a project that combines multiple APIs. You can use our lower level SMS and Voice APIs, our newer higher level Verify and Number Insight APIs, and even complement your use of Nexmo's platform with other APIs.

A Chromebook with a fold-able touch screen. Is it a tablet? A netbook? Is it the future? Just a fad? Whatever is it, is not the status quo. Build a project that's a fresh take. Use our APIs in a way they're not usually used. Accomplish something that's perhaps too ambitious, but is certainly not all too common.

And an RC Helicopter? Well that's just fun. And the best hackathon projects make people smile and want to try it out. Capture that, and you'll be on your way to piloting a helicopter of your own.

Want some extra credit for hacking? Post your Nexmo API key (not secret) in this thread to have some added.

Judging Criteria

  • Combine Components
    Does this use more than just one API? How well does it combine multiple 'components' to make something new?
  • Unique Use
    Is the use something easily found in other applications or systems? Or is it unique, thoughtful, and perhaps a bit surprising.
  • Engaging
    Does it draw people to use it? Is naturally engaging?
