If its 50% chance to win..

its 0.5 ^ n

with n = number of rolls:  with 3 rolls => 0.5^3 = 1/8

So chances are you win 3 times 50/50 in a row are 12.5%.

ok thanks,   can anyone tell me what their personal streak is for rolling the same result on a 50/50 flip?  i think im at around 8 or 9 and happened a few times

The biggest losing streak i had was 12 rolls, all were low and on exact 50% odds. I was playing basic martingale and it was enough to bust my whole
balance. The funny thing is that i rolled 13th roll, but with bet amount 0 since i was busted, and it was a winning one..
8-9 in a row is nothing unusual, i get that streak quite often.

its always the same possibility you bet on, it does not matter if you roll it after 10 losses or 20 losses the chance to lose will still be the same 50 per cent, thats why you shouldnt use any strategies

Made over 10 million rolls there though. Wink

After 8 months of watching player bets I've seen 22 loss and 23 win streaks but Dooglus explained it best.

I don't know if you've seen this thread before, but the longest losing streak at 49.5% on Just-Dice back when we accepted Bitcoin was 32:

  https://bitcointalk.org/index.php?topic=610339.msg7060900#msg7060900

Interestingly, the 2nd longest was 5 bets shorter, at 27.

I would be interested to know if anyone has ever seen a longer losing streak at 49.5% than 32 in a row.

Roughly speaking, the odds against 10 in a row is one in a thousand, 20 in a row is one in a million, and 30 in a row is one in a billion.

So that 32 in a row is a one in four billion shot. The losing streak ended with bet number 594,791,171 and that counter includes all bets, not just those at 49.5%.

Edit: here's a screenshot of the 27-streak:
