Double Attack Blackjack is a popular online casino game that is a variation of traditional blackjack. In this game, players have the opportunity to double their initial bet after seeing the dealer's up-card. The dealer's up-card is dealt face-up and the player can double their bet before the dealer receives their second card. Additionally, the game features Spanish-style decks of 48 cards, which remove the four tens. This variation creates more opportunities for players to hit a natural blackjack. Overall, Double Attack Blackjack is an exciting twist on the classic game, offering players unique betting options and increased chances of winning.
