Code/Racer! Battle it out and learn the code by Treehouse.
Code Racer is a multi-player live coding game that teaches newbies how to code a basic website using HTML and CSS, and tests intermediate and advanced users on their coding speed and agility. Players race against each other and the clock to complete coding challenges, unlocking weapons and rewards along the way.
Treehouse looks really interesting, we like the way they’re using badges as learning tools.
