Blackjack is a timeless classic on the casino floor, having entertained players for centuries. Thus, it has not changed at all, but was just made more accessible in modern iterations. That is how it appears as a live dealer or digital format at every Bitcoin casino app. Roobet offers its own take, and you can play it among its in-house games.
Look for Roobet Games to find Blackjack, together with other titles like Crash and Mines. You can play it on any platform, desktop or mobile, and enjoy full optimisation for crypto betting. Here’s a quick guide to how it works and how to play to get you started:
Basics of Roobet Blackjack
Roobet Blackjack has a max profit of $3,000,000, one of the highest upper caps in a table game. Unlike most dealers at a Bitcoin casino app, Roobet’s blackjack comes with one of the most flexible bet sizes. Minimum bet is $0.01 on both the main bet and the side bets. The maximum main bet is $200,000, but it’s capped at $25,000 for Perfect Pairs and 21+3 bets.
Standard main bet wins pay 1:1 your total wager, but blackjack (natural 21) pays 3:2. The dealer stands on all 17 hands or higher, and a push (a tie) returns all stakes and busts (hand going over 21) automatically lose.
Every round starts with two face-up cards in your hand, while the dealer has one up and one down card. An insurance bet will be offered if the dealer’s up card is an Ace, and you win this bet if it’s a blackjack.
Rules of each action
Every round of blackjack starts with you, and the dealer will only take action after you. After placing a bet and the cards are dealt, you may take any of these actions:
- Hit – Draw a card to add value to your hand.
- Stand – Pass the turn over to the dealer, keeping your hand as is.
- Split – If your hand is a pair, split them into two hands, and draw a card for each.
- Double – Only available at the start of the turn, you hit, stand, and double your bet.
You can keep calling for a hit until you stand or reach a bust. If your hand is a blackjack, you automatically stand. This wins the bet unless the dealer’s hand is also a blackjack, which will result in a push.
Blackjack side bets
The side bets are additional wagers that pay on top of your main bet. They have riskier odds, so they have higher payouts and more niche probable outcomes.
Perfect Pairs
Perfect Pairs are side bets that only payout if you get a pair as a starting hand, which means both cards share the same number (rank). The only deciding factor over which one wins is the kind of pair that you made.
- Suited Pair (same suit): 25:1 – This wins if the pair is of the same suit. Blackjack is played with an 8-stack deck, so there are 8 copies of each card in the game.
- Coloured Pair (same colour): 12:1 – It’s a winning bet if the pair have the same colour. Diamonds and Hearts are both red, while Clubs and Spades are both black.
- Mixed Pair: 6:1 – You win this bet if the pair is from different colours. Combinations include Diamond+Spades, Hearts+Clubs, Diamond+Clubs or Hearts+Spades.
Side bets on Perfect Pairs pay immediately when the cards are dealt. It will not interfere with your decision to split the hand or double down. Cards added by hits and double downs don’t count towards the outcome of this bet.
21+3
The 21+3 side bet is a wager on a potential poker hand forming at the start of the game. This consists of your two starting cards and the dealer’s up card, making the third piece to form a three-card hand. Your options consist of the top five three-card poker winning hands.
- Suited Trips: 100:1 – Each of the three cards shares the same rank and suit.
- Straight Flush: 40:1 – All three cards form a sequence and share the same suit.
- Three of a Kind: 30:1 – The three cards all have the same rank.
- Straight: 10:1 – A sequence is formed with the three cards.
- Flush: 5:1 – All cards share the same suit, but form no rank pattern.
To clarify, a sequence is a progression of numbers like 1, 2, 3 or 5, 6, 7. Suit refers to the colour and shape of the card, namely Clubs, Spades, Diamonds, and Hearts.
Notice that the top two 21+3 bets are combinations of lower-valued wagers. Straight Flush is both a Straight and a Flush, while Suited Trips is Three of a Kind and a Flush. Your side bet will win the bigger payout, as outcomes don’t stack.
Basic strategy for newbies

Knowing what actions to make and when is what you should start developing in blackjack. Generally, you should hit if your hand total is 11 or less, and stand when it’s 17 or more. For when your hand is 12 to 16, stand if the dealer’s up card is 2-6, but hit if it’s 7 to Ace.
For a more advanced strategy, follow the Martingale betting method. It’s a negative progression system where you double the size of your stake after every loss. This way, you only need to win once and recover all losses and make a profit.
There are less volatile betting systems you can learn on the internet. Check out the Labouchere system, which involves tracking your bets in a sequence and cancelling segments. The D’alembert system is a slower version of the Martingale, but it can be harder to track. You should also check out Roobet bonuses. The rakeback system offers a cash return for every bet, giving you boosts to your bankroll whenever you claim them. You should also check the promotions page so you don’t miss out on a good deal.
