Blackjack Rule Variations

Blackjack rules can be varied. Here are several online casino rule variations:

Decks — Online play uses 1 to 8 decks. Fewer decks minimise the house edge.

In some casinos, the dealer must stand on all soft 17. Other casinos require the dealer to hit a “soft” 17 with an ace instead of a “hard” 17. A soft 17 raises the house edge.

Blackjack Peek — When an ace or 10-point card is shown, the dealer peeks for blackjack. Because the dealer does not peek for blackjack in “European blackjack,” doubling or splitting may result in a 2x loss. Blackjack peeking advantages the player.

Double up… Most online blackjack games let you double on any two-card set. Some games only allow you to double on hard sums of 9 to 11, not soft sums with an ace.

In most online blackjack games, you can double after dividing your cards. Some games forbid doubling following a split.

Resplits — You can split your cards again if you draw a matched card. But not all blackjack games enable it.

Resplit Aces — Various blackjack games have different rules for resplitting aces.

Aces can be split with a single card in most blackjack games. Some games let you split aces with multiple cards.

Surrender — In some blackjack games, you can surrender and lose half your wager right away. Surrendering after the dealer has checked for blackjack is called a “late surrender.” Early surrender is available before the dealer checks for blackjack.

7-Card Charlie — A 7-card Charlie is a 7-card hand. Some Grand Virtual games reward a 7-card Charlie. This game uses a 6-card Charlie rule. It’s a Playtech thing.

Casinos have numerous game varieties with varying rules. The following blackjack variants are available: Pontoon, Super Fun 21, Spanish Blackjack, Double Attack Blackjack, Double Exposure.
