Blackjack is undeniably the most popular and strategically deep card game found in any casino worldwide.

Today, online casinos offer dozens of unique blackjack variations, each featuring slightly altered rules or massive side bets.

Spanish 21: A Game Without Tens

Removing the tens mathematically cripples the player, as it makes hitting a natural blackjack much more difficult.

To compensate for this massive disadvantage, the casino introduces several incredibly player-friendly rules to balance the game.

• All standard '10' cards are removed, leaving 48-card decks
• A player's total of 21 always wins, regardless of the dealer's hand
• Players can "rescue" or surrender their hand after doubling down

How to Play Blackjack Switch

In this brilliant variation, the player must place two equal bets and is dealt two completely separate hands.

Additionally, natural blackjacks usually only pay even money (1:1) instead of the standard 3:2 payout.

Double Exposure: Seeing the Dealer's Cards

Double Exposure completely eliminates this mystery by dealing both of the dealer's cards face up for everyone to see.

The most devastating rule change is that the dealer automatically wins all ties (pushes), except for natural blackjacks.

However, you must remember that each unique variant requires a completely different mathematical basic strategy chart.
