In standard Blackjack, one dealer card stays hidden — not here. In Double Exposure at 66ex, both dealer cards are face up from the start. More information means more room for strategy.
The difference becomes clear when compared to the sample hands below
You make decisions without knowing the dealer's hidden card. Hitting from 17 carries a real risk of busting.
The dealer hits on Soft 17 — that's the rule. If you stand on 17, the odds favor you. Make the right call with the right information!

|---|---|---|
| Dealer's Cards | 1 face-up, 1 face-down | Both face up |
| Blackjack Payout | 3:2 | 1:1 |
| Tie Winner | Player gets back | Dealer wins (Push loses) |
| Blackjack Tie | Push (Returned) | Player wins |

| Dealer on Soft 17 | Stand or Hit (variant) | Always Hit |
| Number of Decks | 1–8 Decks | 6 Decks |
| RTP | 99.5% | 99.3% |
In exchange for seeing both dealer cards, Blackjack pays 1:1 instead of 3:2, and the dealer wins all ties except a Blackjack tie. It's a fair trade-off — the overall RTP stays at 99.3%.
Decide with both cards in view — master the right strategy chart and you can play at 99.3% RTP

If the dealer is on 20–21, hit aggressively — give yourself a chance before it's too late.
Remember, ties go to the dealer — aim to finish with just one point more than the dealer's total.

The concept of Double Exposure Blackjack was first introduced in Las Vegas, USA in 1979, where it was also known as "Zweikartenspiel." The idea was straightforward — show the player both of the dealer's cards for extra information, while adjusting certain rules to preserve the casino's edge.
This game at 66ex is powered by Microgaming technology — one of the most trusted casino game developers in the world. Every card deal is controlled by an RNG (Random Number Generator), so manipulation is simply not possible.
A common question: why does the dealer win all ties — is that unfair? It's actually a balancing mechanism. Since both dealer cards are visible, players gain a significant edge — with the right strategy, you can avoid acting on a weak dealer hand. Without the tie rule, the house edge would go negative, meaning the casino would lose money. The rule exists to keep the game balanced.
By the numbers — standard Blackjack has a house edge of around 0.5%. In Double Exposure, seeing both dealer cards gives the player roughly an 8% advantage. The 1:1 Blackjack payout, the tie rule, and Double Down restrictions bring that edge back down. The end result is an RTP of 99.33% — which is extremely player-friendly.
A Soft Hand is one that contains an Ace counted as either 1 or 11 — for example, Ace + 6 = Soft 17. In Double Exposure, Soft Hand strategy works a little differently. Since the dealer's hand is fully visible, Standing on Soft 17 can often be the profitable move.
General rule: with Soft 13–17, Double Down against a weak dealer hand; Hit against a strong one. With Soft 18, Stand if the dealer has 18 or less; Hit if higher. With Soft 19–21, always Stand.
Card counting is a legitimate strategy commonly used in standard Blackjack. In Double Exposure, seeing both dealer cards means more information per round, making counting comparatively easier. However, 66ex uses a shuffled 6-deck shoe with RNG active every round — so the practical advantage of counting on a digital platform is limited.
The best results at Double Exposure Blackjack on 66ex come from following correct basic strategy. If you haven't memorized the strategy chart, you can enable the Strategy Hint feature in the 66ex game interface — it recommends the optimal move for every hand.
