This question may have been asked before, but I wanted to reiterate.

It occurred to me because when I signed up at a new casino, the odds of winning were quite high. I didn't know if it was just coincidence or if it was designed to win. After using the same account for a while, the win rate decreased. I excluded sports betting.

So what do you think?

Are the odds of winning the same on a new and old account?

Perhaps this is also the reason many casinos prohibit the use of multiple accounts.

Or is it just a matter of certain casinos?
