The Math of the 48-Card Deck
Removing the 10s changes the entire deck composition. A standard deck has 52 cards, with 16 cards worth ten points. Spanish 21 uses a 48-card deck where only Jacks, Queens, and Kings represent the ten-value cards. This means only 12 out of 48 cards are tens, reducing your chances of hitting a natural blackjack.
- Fewer Natural Blackjacks: Your odds of getting a natural blackjack drop by about 25% compared to a standard game.
- More Small Cards: The higher concentration of low cards means you will draw more cards per hand on average.
