twelve reds in a row is very very common,there is nothing distantly odd here
if you play on a regular basis,you would be getting 15-17 reds in a row on a 50% chance at least 2-3 times a day
I had 22 and more and not on a single occasion
Absolutely it is very common thing on dice game with 2x payout, I can even say that 12 reds in a row is still low because there are many people got more than 15 or even 20 reds in a row. As long as the bets are verifiable then we should not think something bad of the losing streak.
