Dealer Bust 21 (DB21) is an optional Blackjack side bet that allows players to win odds when the dealer busts. The odds based payouts are determined by the dealer’s up-card. The higher the value of the dealer’s up-card (Ace being the highest), the higher the payout for the DB21 bet. Players can win both their blackjack bet and DB21 bet when the dealer busts. Players may lose their blackjack bet by busting their hand, but still win their DB21 bet if the dealer busts. If all players’ hands bust, the dealer must still play out his hand according to house rules if any DB21 bets have been made. If the dealer does not bust, all DB21 bets lose.
Winning DB21 bets are paid odds based off the dealer’s up-card. The payouts are divided into four categories: the bust cards (2-6), the intermediate cards (7-9), the face cards (10-K) and an Ace. When a dealer busts on a bust card, the players will receive the lowest odds payout. When the dealer busts with an Ace, the players will receive the highest odds payout.
