Blackjack pays 3:2
$10 minimum bet
$400 or more maximum bet
Doubling–down after splitting
Doubling–down on nines
Doubling–down after the second split
Other than Indian reservations or random casinos here and there, if you’re familiar with any specific casinos in Atlantic City that offer these types of rules please shout ’em out.
EDIT: Obviously when I say doubling–down on nines I’m including doubling–down on tens & aces too. Some casinos I’ve been to do not allow doubling on anything other than a ten or an ace so I thought I’d make a point of asking about nines or below.
