This seems really cool, however I find the interface confusing. Here's what I expected: 1. A sandbox where the opponent is a default set of code. You start with the default code as well and there are two buttons. 'Start One Game' and 'Collect Statistics'. The first runs your code in real time against the computer opponent, the other runs many many games to collect win/loss scores on your code. A critical component here is optimization. X games MUST run within 10 seconds. If they don't your code is too slow and must be refactored. After you have a winning win/loss record against the default code you are then presented with a 'Challenge' button. 2. Challenge mode In challenge mode you are facing off against every piece of code ever submitted. Your code gets run automatically against each bot until it looses, and you're given a rank. Here you're also given a 'Collect statistics' button where you try to climb the ladder many times to see, on average, how well your code does. 3. Scoring / Alerts When you reach a new spot on the leader board you are awarded points. Individuals wins mean almost nothing, it's only when you defeat a higher ranked opponent that you get points. If someone else manages to beat you, you are sent an alert so that you can go review that persons code. Overall I think this is a very cool idea and I hope to see it evolve into something a bit more like what I described above!
