Double Exposure Blackjack at 399b — See Both Dealer Cards and Play Smarter
The only blackjack variant where both dealer cards are dealt face-up. Master the strategy, understand the rule trade-offs, and enjoy one of the highest-RTP table games available at 399b — right from Dhaka, Chittagong, Sylhet, or anywhere across Bangladesh.
What Is Double Exposure Blackjack?
Double Exposure Blackjack is a fascinating variant of the classic casino card game where, unlike standard blackjack, both of the dealer's cards are dealt face-up from the very start of the hand. This single rule change transforms the entire decision-making framework — you always know exactly what the dealer is holding, which gives you a powerful informational advantage over a standard game.
At 399b, the Double Exposure Blackjack title is powered by NetEnt and comes with an impressive RTP of 99.33% under optimal strategy — making it one of the highest return-to-player games available on the entire platform. For players in Bangladesh who enjoy card games and want to feel genuinely engaged in each decision, this variant is a compelling choice between cricket betting sessions or alongside a live casino session.
The catch? To compensate the casino for giving away the dealer's hole card, the rules include several adjustments: blackjack pays even money (1:1) instead of the usual 3:2, ties generally go to the dealer, and some doubling-down restrictions apply. Understanding these compensating rules is exactly what this page is designed to help you with.

Basic Strategy Guide
Because you can see both dealer cards, Double Exposure Blackjack strategy differs significantly from standard blackjack. The fundamental principle is straightforward: you know the dealer's total, so base every decision on the precise matchup between your hand and the dealer's known total.
Always Stand on Hard 17+
Regardless of what the dealer shows, never hit a hard 17 or higher. The risk of busting far outweighs any potential gain. This applies even if the dealer holds a strong total like 18 or 19 — you cannot afford to bust chasing an unlikely improvement.
Hit Aggressively Against Strong Dealer Totals
When the dealer holds 17, 18, 19, or 20, you must beat that total outright since ties lose. This means hitting hands you would normally stand on in classic blackjack — including hard 14, 15, and even 16 when needed to match or beat the dealer's known total.
Stand Against Weak Dealer Totals
When the dealer shows a weak total (12–16), they are at high risk of busting. Avoid unnecessary hitting and let the dealer bust naturally. Standing on 12 or 13 against a dealer 14 or 15 is often correct play — the opposite of aggressive strategy used against strong dealer hands.
Double Down Selectively
Doubling is restricted to hard 9, 10, or 11. Double your hard 10 or 11 when the dealer's known total is 12–19 — you have strong chances of landing 19, 20, or 21. Hard 9 doubles are more selective; only double when the dealer shows 13–16 where a bust is more likely.
Splitting Pairs — Be Precise
Always split Aces and eights. Never split fours, fives, or tens. Split nines against dealer totals of 12–18 (you need to beat, not tie). For other pairs like sixes and sevens, split only when the resulting split hand can beat the dealer's exact known total. Since ties lose, be more conservative with split decisions than in standard blackjack.
Never Take Insurance
Insurance is not available in the 399b version of Double Exposure Blackjack. But even if it were, you already know both dealer cards — so the insurance side bet would be completely redundant. This is one less distraction and keeps the strategy clean and focused on your hand versus the dealer's known total.
Quick Action Reference by Dealer Total
Your hard 13–16 vs Dealer 12–16 — let them bust
Your hard 12–16 vs Dealer 17–20 — you must beat their total
Hard 10 or 11 vs Dealer 12–19 — maximum value opportunity
Always split Aces and 8s — never split 5s, 10s, or 4s
Hard 17+ vs any dealer total — no exceptions
Soft hands below 18 vs Dealer 17–20 — keep improving

Frequently Asked Questions
Why does blackjack pay only 1:1 in Double Exposure Blackjack?
Because you can see both dealer cards before making any decision, you hold a significant informational advantage over standard blackjack. To compensate for this, the game reduces the blackjack payout from the standard 3:2 down to 1:1 (even money). This is one of the primary ways the house maintains its edge in Double Exposure Blackjack. Despite this adjustment, the overall RTP remains a competitive 99.33% under optimal strategy — making it one of the better-value table games available at 399b.
What happens when my hand ties with the dealer's total?
In Double Exposure Blackjack, all ties (pushes) go to the dealer — meaning you lose your bet if your total equals the dealer's total. This is a key rule that differs from standard blackjack, where a tie results in your stake being returned. The only exception is when both you and the dealer have a natural blackjack (Ace + 10-value card): in that specific case, your blackjack beats the dealer's blackjack and you win at 1:1. In all other tie situations, the dealer wins.
Can I play Double Exposure Blackjack for free at 399b?
399b offers a demo or practice mode for most NetEnt RNG table games, including Double Exposure Blackjack.

Players in Dhaka, Chittagong, Rajshahi, Khulna, Sylhet, and across Bangladesh can access the game on any modern smartphone or tablet with a stable internet connection.
How does Double Exposure Blackjack strategy differ from standard blackjack strategy?
The most significant strategic difference is that you must play more aggressively in situations where the dealer holds a strong total (17–20), because ties lose. In standard blackjack you might stand on 16 against a dealer 10, but in Double Exposure you often need to hit to match or beat the exact known dealer total. Conversely, when the dealer shows a weak hand (12–16), you can stand on lower totals than usual since the dealer is likely to bust. The strategy is more precise and mechanical because you have perfect information about the dealer's position at all times.
How do I withdraw my blackjack winnings from 399b in Bangladesh?
