Just playing for fun
and I've hit a 0.00549 % of bad streak, or as someone can say 1/200000 odds.

Yeah, something like that since i don't think there is a provably fair in their dice game and when you play to it.
You will likely gonna get burn most of your bankroll with a lot of losing streak than winning streak.
I think it's better to practice dice game using their faucet.
