Has anyone received a reward box yet?

It says you can obtain a reward box by playing or idle. I have played more than 2 hours yesterday and didn't receive the reward box. Can anyone tell me when they get the box, how much time did you spent?

I have yet to recieve one of those reward boxes, I've tried playing and staying idle for a while....still nothing yet.

Its chance-based I believe, nonetheless, I got one last week for idling for a couple of hours.
