I thought of this whilst seeing my dusty PlayStation controller lying about. In video games with fighting like Mortal Kombat, there's typically a section of the game that has training mode. Here, the gamer can practice moves and all sorts of actions that help improve playing skills. I can't recall the last time I played video games, but for Optimizely, it'd be really cool to have a section where testers and people who want to advance their skills can take on challenges. Perhaps with each account, there would be a native project called "Practice." Here, there would be pre-built experiments that each contain missing pieces. An example might be a half-done modal. The goal could be listed in the experiment description, and users would have the opportunity to solve the issue. Each completed would obviously come with a reward such a free trip to the Maldives .
