The original version of the game. Dealer hits on soft 17, split up to 3 hands, double down on any total. The foundation for learning basic strategy.

RTP up to 99.87%The casino covers your splits and double downs on certain hands at no extra cost. More action, more possibilities — though the natural blackjack pays less than in classic.
RTP up to 98.45%RTP measures the average return to player. The higher it is, the better it is for you.
RTPs calculated using perfect basic strategy. Individual results may vary.
Blackjack is the casino game with the best RTP for the player when combined with basic strategy. While slots typically range between 94% and 97% RTP, and European roulette sits at 97.3%, blackjack can reach 99.5% under the right conditions. That means, over the long run, you lose fewer cents per BRL wagered than in any other casino game. And at bb78, the conditions to maximize that RTP are ideal — player-friendly rules, trained dealers, and multiple variants to suit different playing styles.
There is one important thing to keep in mind: blackjack's maximum RTP only applies when you play with basic strategy. Playing by gut feeling — without knowing when to hit, stand, double down, or split pairs — is the fastest way to turn a 0.5% house edge into something much larger. That's why bb78 provides the basic strategy chart for classic blackjack right here — your most essential guide before sitting down at any table.

The secret to blackjack lies in the combination of two factors: you make active decisions throughout the hand, while the dealer is bound by fixed rules. You can stand on 14 against a dealer showing 5 — a strategic choice backed by calculated odds — but the dealer has no such freedom: they must hit on any total below 17, regardless of what you hold. This creates an asymmetry that, when exploited correctly, results in the lowest expected house edge of any casino game.
At bb78, all live blackjack games use trained dealers who follow the publicly stated rules for each table. This matters because certain rule variations significantly affect RTP. For example, a dealer who stands on soft 17 (Ace + 6) is better for the player than one who hits — and bb78 clearly shows each table's rule before you sit down.
Bb78's live blackjack is streamed from studios with high-definition cameras, and you interact with the dealer via real-time chat. Unlike an RNG (random number generator), in live blackjack you can physically see the cards being shuffled and dealt — removing any doubt about the integrity of the game. For many Brazilian players who have never had access to a land-based casino, it's the first time they experience that level of immersion.
Bb78's live tables run 24/7. You can play from your phone or computer, deposit via Pix or credit card, and be at the table in under 2 minutes. Withdrawals work just as smoothly: once you win, request a Pix withdrawal and the funds land in your Nubank, Itaú, Bradesco, Banco do Brasil, or any other bank account in as little as 5 minutes.
The first tip is straightforward: study the basic strategy chart until you no longer need to look it up. There's plenty of free information available on blackjack strategy, and memorizing the correct decision for every card combination is the single most important step toward reducing the house edge as much as possible.
The second tip is about bankroll management. In blackjack, short-term variance can be significant even when you're playing correct strategy. If you have R$ 200.00 to play with, don't sit at a table with a R$ 100.00 minimum bet — that gives you just two hands before you're out. Ideally, you should have at least 20 to 30 times the minimum bet as your bankroll for that session. At bb78, with tables starting from R$ 5.00, you can play comfortably even with a smaller bankroll.
The third tip is about side bets. Many blackjack tables offer side bets like Perfect Pairs or 21+3 with seemingly attractive payouts. The catch is that the RTP on these bets is usually far lower than the main game — often below 95%. If your goal is to maximize playing time and minimize expected losses, skip the side bets and stick to the main game with basic strategy.
Place your chips in the betting area before the dealer deals the cards. Stay within the minimum and maximum limits of your chosen table.
You and the dealer each receive two cards. One of the dealer's cards is face down (the hole card). The goal is to reach 21 without going over.
Hit, Stand, Double Down, Split, or Surrender. Apply basic strategy to every decision.
The dealer reveals their hole card and follows the table rules. If your total is higher without exceeding 21, you win. Blackjack pays 3:2 at most bb78 tables.
