How much actual data collection time do you estimate to reach 95% confidence that you get more than random expected 66 rolls?

I was once crazy enough to do such an experiment. The actual number is surprisingly low. I just tested for 6s on a single die, though, and had no box, but just a cup. IIRC after 300-400 rolls I had a significance >95%. The first series was of course only good to calibrate the experiment. Thus, after I got that result I did the experiment again, this time with a predefined number of rolls, say 400. After these 400 rolls, I had again too many 6s with significance >95%. I think, I even changed the dice between the experiments.
