ClueCon's Coder Games is a day filled with games and fun for every attendee. Whether you like to code your way to the prize or are a builder at heart, there is something for everyone. You can work as a team or go solo as you utilize the provided materials, including a 3D printer, to build your creation!


FreeSWITCH Free For All


Most Innovative use of FreeSWITCH to solve any problem - Win a Bartop Arcade Machine

Solution can include C modules, Scripts such as LUA or JS, ESL or any combination. Try to use the communication features from FreeSWITCH such as SIP or WebRTC. Since FreeSWITCH is open-source The solution should use FreeSWITCH as a key component and be reproducible by others. We may consider making it part of FreeSWITCH!

Raspberry Pi Makers

3D Printer printing an old phone Raspberry Pi Makers is a maker challenge using a Raspberry Pi and arduino sensors to build a machine that can solve a simple challenge. We provide the Raspberry Pi, and you provide the solution! Last year, the Raspberry Pi Maker winners crafted an LED enabled coffee ordering device using Flowroute’s SMS! What will you create? The possibilities are endless!

Flowroute Challenge

An Arduino board

Most innovative IoT use of Flowroute - Win a $500 Flowroute credit, an Amazon Echo, coffee maker and grinder, and fantastic coffee beans from the coffee capital of the USA.

The challenge is to integrate communications into a personal assistant or smart device such as Alexa, Google Home to enable users to interact in a more intuitive, personal way using calling and messaging. A few use case examples are the ability to request food delivery, set up two-factor authentication, or request general information such as directions, the weather, or traffic alerts. Stop by the Flowroute booth to get hands-on guidance to get up and running quickly. You can access Flowroute’s APIs and documentation at


An Arduino board CodeFights is about improving your coding skills by solving programming challenges. Some modes are single-player and some are multi-player. Each one is a little different, so be sure to try them all! Take the time to dig into more complicated problems, many submitted by the CodeFights community. Rise up the leaderboard by delivering the shortest solution in your language of choice, or passing as many tests as possible. Submit your own challenge for the community to solve for a chance to be chosen as the featured Challenge of the Week!

Ytel's message360 Challenge

Ytel Challenge

Best "hacked" app - Win a PS4 and a $100 message360 credit

Using the Ytel message360 API makes it easy to integrate communications functionality such as voice, text, email and direct mail into any application, with text/SMS as a core feature. We challenge you to “hack” the API to create your own unique, user-friendly app. Access API documentation and start building now!

FreeCYCLED Hacks

3D Printer printing an old phone Do you like to apply your hacking skills to real life too? Have you ever used a paperclip and a rubber band to fix something? Then this is the competition for you! Show off your skills and win a prize! Build a contraption out of everyday materials that can move a ping pong ball one one foot forward.

Dangerous Demos

Dangerous Demos The Dangerous Demos are coming to ClueCon 2017! Prepare to watch in awe as attendees that you know and love attempt to beat the clock! Prizes will be awarded based on a variety of factors from the most spectacular failure to the most impressive demo! You don't want to miss this exciting event! Do you think you have a demo dangerous enough to impress the judges? Register HERE!

Telnyx Challenge

Telnyx Challenge

Most innovative game built using Telnyx voice and messaging APIs - Parrot AR 2.0 Elite Edition Quadcopter

Rock, paper, scissors via SMS? Or maybe it’s a choose your own adventure game. How about a fun trivia challenge? Get creative! We challenge you to create an automated game using our voice and messaging APIs found here. Get free access today with our Mission Control Portal and start building – we’re excited to see what you come up with!

Bandwidth's "One Giant Leap for AI"


Best example of an AI built using Bandwidth APIs - Win a Nintendo (NES) mini

To communicate is human. Or is it? Automated, AI-driven systems like IVRs and chat bots have become critical customer touchpoints. For Bandwidth's challenge, create a human experience with Bandwidth’s voice, messaging, and numbers APIs. The obvious solution would be adding sentiment analysis to a text message response or call tree. The winning demos will combine communication, the efficiency of automation, the power of data, and a human touch.

LiveSwitch HackRTC


Most innovative RTC application built with LiveSwitch - Win an Oculus Rift

LiveSwitch enables real-time communications (RTC) over forwarded (SFU/multi-stream), mixed (MCU/single-stream), and peer connections, all at the same time, and all in the same session. A server-side SIP connector enables phone call-in to a live session using FreeSWITCH or a SIP trunk like Flowroute. The challenge is to build an innovative real-time web, desktop, or mobile application that uses LiveSwitch. You can download and install LiveSwitch at (required for SIP integration) or use our hosted server at The API documentation and Getting Started guide is found at
