Spanish 21 is similar to traditional Blackjack but with more options and payouts. One difference is that all numbered 10  cards are removed from the deck leaving 48 cards in each deck. Jacks, Queens and Kings count as 10. Aces count as 1 or 11 (whatever is to the Player's advantage).

Spanish 21 is played with 6 or 8 decks of 48 cards throughout this casino. Each individual deck has had the four 10's cards removed. The cards are dealt face up, one to each player and then one to the Dealer followed by a second card to each player.
