At an online casino the odds are pretty low. In a real casino almost impossible.

How would I calculate this as a series...what are the odds of getting zero blacks in 20 single zero roulette spins?

[DrStale]

Same as the odds of any other combination of reds/blacks over 20 spins

[Kaabee]

odds of non-black = 19/37. raise it to the 20th power. 1 in 615124.

[chipper]

slim... but on an online game controlled by a piece of software and code that knows what/where you are betting, obviously pretty good!

[Pride]

betting there is very simple. they let you win a little in the beginning and that gets you to feel pretty safe about it.

then they fuk you.

win some and get the hell out

>>win some and get the hell out<<

Best advice ever given when it comes to an online casino !

[Mikail]

and these fuks got the nerve to say its a RNG

I'm sure more than 20 in a row has been done, there is no such thing as a legitimate online casino. as soon as you change your color, it will change with you, lose-lose.

In my local casino happen 8 times in a row the same number, anything that is a possibility will happen doesnt matter the odds.
