- Restrictions on doubling down
- Reduced blackjack payouts (6:5 vs 3:2)

Single Deck Blackjack
Single deck blackjack deals cards out of just one deck. It offers several advantages for skilled players:
- Highest probability of getting a natural blackjack
- Easier card counting as only 52 cards in the deck
- Player-friendly rule variations more common
Make sure to only play single deck blackjack games that pay 3:2 on blackjack. Tables that pay 6:5 tilt the odds back towards the casino.

| Late surrender allowed | +0.07% |
| Double any two cards | Improves player edge |
Put in the work to accurately count cards in single deck games and you can gain a significant mathematical advantage against the house long term.
European Blackjack
European blackjack games only deal cards out of two decks shuffled together. This double deck game offers a compromise between single deck and standard multi-deck blackjack.
Key advantages of European blackjack include:
- Fewer decks make card counting viable
- Player-friendly rules like late surrender and re-split aces common
- Lower house edge than standard blackjack
European tables incorporate the following rule variations:

While not as advantageous as true single deck, double deck European blackjack allows skilled players to gain an edge while bringing less scrutiny than very small shoe games.
Free Bet Blackjack
Free bet blackjack offers an exciting twist on traditional blackjack. Whenever you make certain hands, the dealer will give you a “free” side bet equal to your original wager.
This blackjack innovation adds extra volatility but also improves your long-term expected value. Common free bet hands include:
- 20+ card hard totals
- Hard 16 vs dealer face card
- Five card hands less than 21
- Busted hands over 21 when dealer also busts
Free bet blackjack uses 8-decks, offers favorable rules for players and can be readily counted:

| Dealer hits soft 17 | -0.2% |
| Late surrender allowed | +0.07% |
| Double after splits allowed | Improves player edge |
The excitement of free side bets gives blackjack an added dimension while rewarding skilled play. Just be wary of gimmicky proprietary side bets on such tables.
Double Exposure Blackjack
Double exposure blackjack reveals the dealer’s first two cards. This gives players more information to make better decisions.
Knowing the dealer’s upcard and hole card reduces the house edge. However, casinos counter this by making other key rule changes:
- Dealer wins all ties
- Blackjack only pays 1:1 instead of 3:2
- Player automatically loses if getting more than 21 cards
Aside from the modified payouts, double exposure blackjack incorporates positive rules:

| Double on any two cards | Improves player edge |
If you play perfect basic strategy, the house only holds around a 0.2% edge in double exposure blackjack. Just be mindful of the difference in blackjack payout.
Blackjack Switch
Blackjack Switch enables an exciting option to switch your first two cards with the second hand. If dealt a poor 12, you can swap it for a more favorable 16 or vice versa.
Switching your cards adds a new strategic dimension. Blackjack Switch also incorporates positive rules:

| Rule | Odds Impact |
| Option to switch first two cards | Adds skill factor for players |
| Dealer pushes all 22 ties | Saves player 0.06% |
| Late surrender allowed | +0.07% |
| Re-split aces allowed | +0.03% |
Combined with classic blackjack rules, the option to Switch cards lowers the house edge down below 0.5% according to simulation. However, ensure your Switch strategy is optimal.
Mastering any of these 5 blackjack variants will enable you to gain an advantage against the house as a skilled player. Just be sure to use accurate basic strategy charts that are specific to each blackjack option. Avoid dubious side bets and watch for penetration to capitalize on your skill edge in 2025.
