this is the real deal

This looks great. Built by CodeFights, which is a great place to work on your programming in a number of languages, with daily challenges, head-to-head battles and company bot battles that can land you jobs at big tech companies like GoDaddy, Uber and DropBox.

If the question really gets difficult this is a very good evolution over existing OJs.

Something like Codin Game. I'm up for it!

This could be a fun way to find new hiring candidates!

This is the best game you will play today!

Great idea!
