Now, while Spain may or may not be Blackjack's country of origin, the reason why Spanish 21 has its name is because of its use of a 48-card Spanish deck. You can play the game using the standard French suited 52-deck if you remove the four ten-spot cards.

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).
