Does anyone else ever feel like they're luckier at some sites compared to others, even if the edge and everything is the same?
If you toss 10 coins every day, sometimes you will get 3 heads, sometimes you will get 5 heads, and sometimes you will get 8 heads.
Similarly, if you play on a few different sites, you will win more on a site, and win less on a site.
But that doesn't matter, as the bets are independent and a "lucky" history doesn't give you a benefit in future bets.
