The table where the dealer's cards are already showing
You sit down at a blackjack table, buy in, and the first thing you notice is that the dealer's two cards are both face up. Nothing is hidden. If you have played blackjack before, this looks wrong, because the standard game you remember gives the dealer one card up and one card down. What you are looking at is not a mistake and not a new invention. It is a deliberate rule variant, and the reason it exists is that the casino has already taken something away from you in exchange for showing you that second card.
The face-up format is usually called double exposure blackjack, and its defining feature is exactly what the name says: both dealer cards are exposed before you act. The catch, and it is a real one, is that the rest of the rules are rewritten to compensate. The most common change is that the dealer wins all ties, or all ties except a tied blackjack. That single adjustment is enough to rebalance the game, and it explains why a table can afford to show you everything.
There is a second, quieter reason some games show all cards. In many jurisdictions and on many newer tables, the dealer no longer physically holds a hole card at all. The cards are dealt face up from a shoe, and the dealer simply does not take a second card until every player has finished acting. This is a procedural choice, not a strategic gift. It changes when the dealer's second card appears, not whether the house has an edge.
Two different reasons, two different games
The phrase "turn up all cards" covers two situations that look similar from the rail but are mechanically different. One is a promotional or variant game where both dealer cards are visible from the start and the rules have been changed to pay for that visibility. The other is a standard game using a no-hole-card procedure, where the dealer's second card simply has not been dealt yet. Mixing these up is the most common source of confusion about face-up blackjack.
| Feature | Double exposure variant | No-hole-card standard game |
|---|---|---|
| Dealer's second card | Dealt face up at the start | Not dealt until players finish acting |
| What the player sees before acting | Both dealer cards | One dealer card only |
| Tie rule | Usually dealer wins ties | Tie is a push |
| Purpose of the format | Variant game with rebalanced rules | Table procedure to speed play and reduce card handling |
| Strategic charts | Separate charts required | Standard basic strategy applies |
Both formats are legitimate table games. Neither one is a cheat, a glitch, or a sign that the casino is being generous. The difference is what the player is being shown and when, and what the player gives up in return.
Why a casino would ever show you both cards
The answer is arithmetic. In standard blackjack, the dealer's hidden card is valuable information that the player does not have. In a double exposure game, the player gains that information, and information has a price. The house collects the price by rewriting the tie rule. When the dealer wins a tied hand, a result that used to be a push becomes a loss. That happens often enough to more than offset the advantage of seeing the second card.
The game also typically pays a blackjack at even money instead of the usual higher payout, and it may restrict doubling or splitting. Each of those changes is a rule, printed on the table or available in the game's help panel, and each one shifts the expected rate of loss. None of them is hidden. The whole design is transparent, which is part of why the variant exists: it gives players a game that feels more open while keeping the mathematics firmly with the house.
For the no-hole-card version, the motivation is procedural. A dealer who never touches a face-down card has fewer opportunities for a card to be marked, bent, or misread. The shoe deals every card face up, the cameras see every card, and the pit can resolve disputes without anyone having to reconstruct what a hidden card was. It is a surveillance and speed decision, not a strategic one.
What changes for you at the table
Your first decision point is the same in every blackjack format: you buy in, the dealer converts your cash to chips, and you place a wager in the betting circle before any cards are dealt. What changes after that depends on which face-up game you are in.
In a double exposure game, you see both dealer cards before you decide anything. That changes the logic of every hand. You no longer have to guess whether the dealer has a ten underneath. You can see it. But the changed tie rule means a hand of 18 against a dealer 18 is not a standoff; it is a loss unless the specific table says otherwise. Strategy charts for standard blackjack do not transfer. You need the chart built for the exact rule set on that table, the same way basic strategy in standard blackjack depends on deck count, dealer stand rules, and doubling and splitting permissions.
In a no-hole-card game, nothing about your strategy changes. You see one dealer card, you act on your hand, and only then does the dealer draw the second card. The reason the game can look like all cards are turned up is that every card, including the dealer's eventual second card, is dealt face up. There is simply no hidden card at any point. The standard basic strategy for that table's other rules still applies.
The main bet and the side bets
The main bet in any blackjack game is the wager in your circle. The objective is mechanical and identical across formats: finish with a hand total closer to 21 than the dealer's without exceeding 21. A hand over 21 loses immediately, regardless of what the dealer later draws. In a standard game, a tied total is a push and your wager is returned. In the double exposure variant, the tie rule is usually the first thing printed on the layout, because it is the rule that most changes the game.
Side bets are separate wagers with their own payouts and their own edges. They are settled independently of the main hand. A table may offer a pair bet, a suited-trip bet, or some other proposition tied to your first cards or the dealer's upcard. The house edge on a side bet is not the same as the edge on the main game, and it is usually higher. The information panel on the table or in the game's help screen states the payout for each side bet, and that payout is what determines its edge. Seeing the dealer's cards does not make a side bet a better wager.
Where the numbers are printed
You do not need to memorise a house edge to play correctly, but you should know where the table states its own terms. The felt itself carries the critical rules: blackjack payout, dealer stand rule, tie rule, doubling and splitting permissions, and any side bet payouts. The game's help or information panel, available on the screen for electronic tables and usually on a printed card at live tables, carries the game name and any variant-specific conditions. If a table is a double exposure game, it will say so. If a table uses a no-hole-card procedure, the dealer will usually announce it or the felt will indicate that the dealer draws after all players have acted.
The return to player figure, where one is published, is a theoretical percentage of total wagered money a game returns to players over a very large number of hands. It is a long-run statistical average, not a per-session guarantee. House edge and RTP are complements: they sum to 100% for the same game. A rule change like the dealer winning ties moves that number, and the published figure, where it exists, reflects the rule set in use. Where no figure is published, the rule set on the felt is what you use to compare one table with another.
Procedural mistakes new players make
The first mistake is assuming that seeing both dealer cards means the game is easier to beat. It is not. The variant rules are designed so that the information advantage is priced back out. The second mistake is applying standard basic strategy to a double exposure table. The charts are built from a specific rule set, and a rule set where the dealer wins ties produces different decisions. Using the wrong chart is not a minor error; it is playing a different game than the one the chart describes.
The third mistake is treating a no-hole-card game as if the dealer's second card is already known. It is not. The card has not been dealt. Your decisions are made against one visible dealer card, exactly as in the standard game. The only difference is that the second card appears later, face up, instead of being hidden from the start.
FAQ
Is face-up blackjack the same as double exposure?
Not always. Double exposure is a specific variant where both dealer cards are dealt face up before the player acts, and the rules are changed to compensate, usually by making the dealer win ties. A no-hole-card game also deals every card face up, but the dealer's second card is not dealt until after all players have finished, and the standard rules otherwise apply.
Does seeing the dealer's cards change the house edge?
Seeing both dealer cards changes the player's information, but the variant rules change the mathematics in the other direction. The tie rule, blackjack payout, and any doubling or splitting restrictions are what determine the edge on a double exposure table. The visible cards alone do not make the game more favourable.
Can I use a normal blackjack strategy chart at a face-up table?
Only if the table is a standard no-hole-card game. For a double exposure variant, the changed tie rule and any other modifications mean you need a chart built for that exact rule set. Strategy charts derive from specific rules, and a chart for one game does not transfer to another with different payoff conditions.
