Blackjack is, without exaggeration, the casino game with the best balance of strategy and return on the market. While a slot machine pays back an average of 94–96% of all money wagered over time, blackjack played with correct basic strategy can reach an RTP of up to 99.65% — meaning the house edge is just 0.35%. That razor-thin margin makes blackjack the game of choice for players who understand probability and want real control over their decisions.
On 47bet, blackjack is available in more than 18 variants, in both live format with real dealers and software format with adjustable speed. The catalog features the world's top providers — Evolution Gaming and Pragmatic Play Live — delivering ultra-high-quality streams, authentic casino ambient sound, and the option to interact in Portuguese with dealers at all live tables.
How blackjack works — basic rules for beginners
The goal of blackjack is straightforward: build a hand with a higher value than the dealer's without going over 21. Each card has a value: number cards are worth their face value, face cards (J, Q, K) are worth 10, and an Ace can be worth 1 or 11, whichever is more favorable for your hand. At the start of each round, you and the dealer are each dealt two cards. One of the dealer's cards is face down — you only see one.
From there, you have the following options: Hit (request another card), Stand (keep your current hand), Double Down (double your bet and receive exactly one more card), Split (split a pair into two separate hands) and, at some tables, Surrender (surrender and recover half your bet). If you go over 21, you "bust" and lose automatically — even if the dealer also busts afterward. That is what creates the house edge: the player acts first.
Natural blackjack and the 3:2 payout
If your first two cards form a natural blackjack — an Ace plus a face card or 10 — you win with a special 3:2 payout (on a R$ 100.00 bet, you receive R$ 150.00 in profit). At the tables of 47bet, natural blackjack pays 3:2 on most variants, which is the best possible rule for the player. Watch out for tables paying 6:5 instead of 3:2 — that seemingly small change dramatically increases the house edge and is one of the most important things to check before sitting down at a table.
Basic strategy — where it all starts
Basic blackjack strategy is a set of mathematically optimized decisions for every possible combination of cards between your hand and the dealer's visible card. It was calculated by computer and represents the play that minimizes the house edge in each situation. Following basic strategy with discipline is what pushes the RTP to its maximum of 99.65% on the classic tables at 47bet.
Here are some concrete examples: if you have 11 and the dealer is showing any card from 2 to 10, the correct play is always to double down. If you have a pair of 8s, the right move is always to split — regardless of what the dealer is showing. If you have 16 and the dealer is showing 7 or higher, you should hit even with the risk of busting, because the odds favor that decision in the long run. Each of these rules has solid mathematical logic behind it, and memorizing them — or at least reviewing them before you sit down at the table — makes a real difference in your results.

One feature Brazilian players at 47bet value most is the availability of Portuguese-speaking dealers. While many international platforms only offer dealers in English or Spanish, 47bet has made Brazilian players' comfort a priority by providing service in our language — especially at the highest-volume tables like Classic Blackjack and Infinite Blackjack.
Side bets — how they work and when they're worth it
Beyond the main bet, several tables at 47bet offer side bets that add variety to the game. The most common ones are: Perfect Pairs (a side bet on receiving a pair in your first two cards — higher payouts for identical or same-color pairs), 21+3 (your first two cards plus the dealer's visible card form a poker combination such as a straight or flush), and Insurance (insurance when the dealer shows an Ace, paying 2:1 if they have a natural blackjack).
One important note: side bets carry a significantly lower RTP than the main bet. Perfect Pairs, for example, has an RTP of around 95%, while 21+3 sits at roughly 96%. From a purely mathematical standpoint, side bets are not recommended for players focused on maximum return. That said, they deliver moments of intense excitement — a suited flush in 21+3 pays 100:1 — and can be used occasionally by players who want to add an extra shot of adrenaline to their session.
