European no-hole-card rule. A rule used in blackjack where the dealer does not take a hole card. The dealer hand gets a second card only after all player hands are finished. If the dealer gets a blackjack, a player who has doubled down or has split loses not only his original bet but all additional bets. The name of this rule is derived from the fact that many games in Europe and abroad are played with this rule in effect. It is not the norm in most American and Canadian casinos.
