Blackjack is the casino game with the highest return to player when played well — and 79x1 brings together the best live tables, classic versions, and exclusive variants all in one place. Deposit via Pix and take your seat now.
Real dealers, high-definition cameras, and a full casino experience on your phone or computer — 24 hours a day, 7 days a week.
From classic to cutting-edge — each variant has its own rules, RTP, and complexity level. Find the table that matches your style.
Classic European-rules blackjack with 6 or 8 decks. The dealer stands on soft 17, players may double on any two cards, and pairs can be split up to 3 times. The foundation of the game — ideal for mastering basic strategy before moving on to more complex variants.
Unlimited players at the same table — everyone receives the same cards and makes independent decisions. Perfect for players who don't want to wait for a seat and want to jump into the action at any time. Available 24/7 at 79x1.
Ultra-fast rounds with reduced decision time — whoever acts first gets card priority. Ideal for players who know basic strategy well and don't want to wait on others. Rounds completed in 25 seconds or less.
One of the most exciting variants available at 79x1: you can multiply your bet by 2x, 3x, or even 4x on any hand, including after splitting pairs. The 9s and 10s are removed from the deck, boosting your edge on strong hands like 11 and 10.
On hands totaling 9, 10, or 11, the casino covers the Double Down for you — you risk nothing extra. Splits on pairs (except 10s) are also covered by the casino. If the dealer busts with 22, all bets (except natural blackjack) are returned as a push.
Played without the 10s in the deck — only jack, queen, and king count as 10-value cards. To make up for this, the variant offers special bonuses: a 5-card 21 pays 3:2, a 6-card 21 pays 2:1, and a 7-or-more-card 21 pays 3:1. Surrender is allowed at any time.
A fully digital version powered by a certified random number generator — no live dealer. Ideal for practicing basic strategy in demo mode at no cost, or for playing at your own pace without the time pressure of other players.
An exclusive single-seat table — just you and the dealer. No other players making slow decisions or disrupting your pace. Available across multiple betting ranges, including high-stakes options for those who want complete privacy.
Join regular blackjack tournaments with real cash prizes — no extra entry fee for users with an active balance. Everyone starts with the same chip count, and the goal is to finish with more chips than the other players.
Among all the casino games available at 79x1, blackjack stands out for one very simple reason: it's the only game where the player's decisions directly impact long-term results. With slots, you hit spin and wait. With roulette, you pick a number and hope. With blackjack, you decide whether to hit, stand, double, or split — and each decision mathematically affects the expected return of your session.
With perfect basic strategy — available in public charts and applicable to any game — the house edge in classic blackjack drops below 0.5%. That translates to an RTP of roughly 99.5%, the highest of any table game in the online casino. No slot comes close; most land between 95% and 97%.
Basic strategy is no secret and not hard to find — it's rooted in mathematical probability and was calculated by computers analyzing millions of hands. For every possible combination of the player's cards against the dealer's up card, it tells you which decision is statistically most advantageous. It doesn't guarantee winning every hand, but it reduces the house edge to the lowest possible level over time.
79x1 makes the basic strategy chart available directly on the platform, so you can reference it while playing at the digital tables. At the live tables, the decision time is enough for players who've already internalized the most common moves — with a few weeks of practice, basic strategy becomes almost second nature.
The 79x1 Live Casino section features live blackjack tables as its main attraction. Real dealers, HD cameras, a sleek interface, and lag-free streaming — all designed to bring the land-based casino experience to your phone or computer screen.
79x1's studio partners — Evolution Gaming and Pragmatic Play Live — are world leaders in live casino. Tables run 24 hours a day, 7 days a week, with dealers rotating each shift. Video quality is full HD, and the platform automatically detects your connection speed to adjust the resolution without interrupting the stream.
In the live chat at each table, you can interact with the dealer and fellow players — a social experience that comes close to the feel of a land-based casino. Dealers are trained to keep the conversation going and create a welcoming atmosphere, whether you're betting R$ 5.00 or R$ 5,000.00 per hand.
For players who prefer mobile, 79x1 has optimized the live blackjack interface for smaller screens: action buttons (hit, stand, double, split) sit at the bottom of the screen for easy thumb access, while the dealer video occupies the top. It works seamlessly on both Android and iOS, with no app download required.
Use this table as a reference before playing at 79x1. H = Hit, S = Stand, D = Double Down. Based on 6-deck blackjack with dealer standing on soft 17.
| Your Hand | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | Ace |
|---|---|---|---|---|---|---|---|---|---|---|
| 5 – 8 | H | H | H | H | H | H | H | H | H | H |
| 9 | H | D | D | D | D | H | H | H | H | H |
| 10 | D | D | D | D | D | D | D | D | H | H |
| 11 | D | D | D | D | D | D | D | D | D | H |
| 12 | H | H | S | S | S | H | H | H | H | H |
| 13 – 14 | S | S | S | S | S | H | H | H | H | H |
| 15 | S | S | S | S | S | H | H | H | H | H |

| 17 – 21 | S | S | S | S | S | S | S | S | S | S |
H = Hit · S = Stand · D = Double (if doubling is not allowed, hit). Dealer's card at the top of the column. Rules: 6 decks, dealer stands on soft 17, double on any two cards, split up to 3 hands.
Always split Aces and 8s — regardless of the dealer's card. Never split 5s (treat them as 10 and double instead) or 10s (20 is already a very strong hand). For all other pairs, the decision depends on the dealer's upcard: pairs of 2s, 3s, 6s, and 7s should be split when the dealer shows 2 through 7; pairs of 9s when the dealer shows 2 through 6 or 8 through 9.
When the dealer shows an Ace, the table offers an "insurance" option — a side bet of up to half your original wager that pays 2:1 if the dealer has blackjack. Mathematically, insurance is disadvantageous for the player in most situations and increases the house edge. Basic strategy recommends always declining insurance, except for card counters in specific scenarios.
Never played blackjack online? In under five minutes you can be seated at a live table or on the digital version. Here's how:
Go to the registration page and enter your name, CPF, email and password. The process takes under two minutes and your account is active as soon as you confirm your email. No extra documents needed to get started.
Deposit from R$ 10.00 using Pix. Generate the key on the platform, open your banking app (Nubank, Itaú, Bradesco, Banco do Brasil, or any other Pix-supported bank) and confirm. Your balance appears in seconds — ready to play. Your first deposit automatically triggers a bonus of up to R$ 1,000.00.
In the 79x1 casino menu, find the Blackjack section. You'll see the available live tables with details on betting limits, dealer, and open seats — plus the digital versions for players who prefer to play without live interaction.
Click on a table that fits your budget. Set your bet amount, wait for the round to begin, and receive your cards. Feel free to refer to a basic strategy chart if needed, especially at first — there's no time pressure in the digital versions.
The goal of blackjack is straightforward: get as close to 21 as possible without going over, and finish with a higher hand value than the dealer. Number cards are worth their face value, face cards (jack, queen, and king) are worth 10, and an Ace can be worth 1 or 11 — whichever benefits your hand more.
79x1 offers free demo versions of its digital blackjack tables, where you can practice the rules and basic strategy with play chips at no cost. It's the best way to get comfortable with the game before sitting down at the live tables with real money.
Learning basic strategy is the first step to playing well at 79x1. The second — just as important — is bankroll management: knowing how much to bet on each hand relative to your total available balance for that session.
A practical rule widely used by experienced players is the 5% rule: never bet more than 5% of your total session balance on a single hand. If you have R$ 200.00 for the session, each hand should be at most R$ 10.00. This ensures you have at least 20 hands to ride out a losing streak without busting your bankroll before your luck turns.
Another approach is the unit system: set a base amount (for example BRL 5.00) as one unit and always bet that fixed amount, regardless of whether you won or lost on previous hands. Systems that increase bets after wins or losses — such as Martingale — are mathematically dangerous over the long run and are not recommended for anyone who wants to enjoy blackjack sustainably at 79x1.
79x1 provides a complete history of every hand played, including outcome, bets, and balance at each point. Reviewing this history periodically helps you spot patterns in your decisions and fine-tune your strategy for future sessions.
79x1's live blackjack is built to run seamlessly on mobile — and most Brazilian players access the platform via smartphone. The mobile interface places the dealer's video feed at the top of the screen and the controls at the bottom, right within thumb's reach.
Video quality adjusts automatically to your connection — even on a slower 4G network, the stream is stable enough to follow every card being dealt. On faster connections, video switches to full HD automatically.
Making a deposit and playing blackjack on mobile at 79x1 takes under two minutes: open your banking app, send the Pix, switch back to 79x1, and your balance is already there. No waiting for a boleto to clear or a manual transfer approval.
For players who like to game on the go — during a work break, at home watching the Brasileirão, or waiting somewhere — 79x1's digital blackjack (RNG version, no live dealer) is even more convenient. You play at your own pace, pause whenever you want, and pick right back up where you left off.
