Rumba Blackjack 1 rule card: eight decks, S17, 3:2
Our sample is Ezugi's Rumba Blackjack 1 (tables 2, 3 and 4 also run in the lobby): a Latin-themed studio with classic rules. With no studio page to hand, we took the rules from two independent reviews and listed only what both agree on.
| Item | Value | Source |
|---|---|---|
| Table and studio | Rumba Blackjack 1 – Ezugi | Dukat.bet lobby, 11 October 2026 |
| Decks | 8 decks | two independent sites |
| Goal | a higher total than the dealer, 21 at most | mathematical constant |
| Dealer rule | stands on every 17 (S17) | two independent sites |
| Blackjack pays | 3:2 | two independent sites |
| Doubling | on any two cards, also after a split | two independent sites |
| Split | once per pair; split aces get one card each | two independent sites |
| Insurance | 2:1 when the dealer shows an ace | two independent sites |
| Surrender | not offered | one independent site |
| RTP | 99.50% for the base game, per the reviews | two independent sites |
| Table limit | we do not publish it | not published |
Handle the RTP with care: one source gives it for Ezugi's whole blackjack series, not Rumba alone, and it assumes flawless basic strategy.
Ace, face card, number card: what each card is worth towards 21
Number cards count at face value; tens and face cards all count as 10. The ace is flexible — 1 or 11, whichever suits your hand.
If the ace can count as 11 without busting, the hand is ‘soft’. Ace–six is a soft 17: you can safely hit, since a big card turns the ace back into 1. A ‘hard’ hand has no such cushion.
A blackjack is 21 from your first two cards (ace plus a ten-value card); at Rumba it pays 3:2. If the dealer has one too, it is a push and your stake returns. Busting loses at once, even if the dealer busts later.
Five buttons on screen: hit, stand, double, split, insurance
At a live table you choose with buttons while a short countdown runs, and each has its own condition.
| Decision | What it does | When available |
|---|---|---|
| Hit | you ask for another card | as long as you have not bust |
| Stand | you close your hand | any time on your turn |
| Double | stake doubled, then exactly one more card | on the first two cards; at Rumba also after a split |
| Split | a pair becomes two hands with equal stakes | with a pair; once at Rumba |
| Insurance | a half-stake side bet on dealer blackjack, paying 2:1 | when the dealer's upcard is an ace |
Insurance is a separate bet, not protection: its odds are worse than the 2:1 it pays, so basic strategy always declines it. If the timer runs out, many interfaces stand for you; the table's help screen says which.
When every seat is taken, there is Bet Behind: you back a seated player's hand and live with their decisions. Your money, somebody else's judgement. Our sources say nothing on Rumba's seat count or Bet Behind rules.
The dealer does not think: S17, H17 and the upcard
The dealer has no choice: draw to 17, then stop. Soft 17 is where tables differ: S17 stands on it, H17 draws once more. The reviews list Rumba Blackjack 1 as S17, slightly better for the player.
For your decisions, the dealer's upcard is the key. A 2 to 6 is ‘weak’ and often leads to a dealer bust. From 7 to the ace it is ‘strong’, and your hand needs improving.
Pragmatic Play says all its live blackjack titles allow doubling after a split, with basic strategy reaching up to 99.59% in some variants. We tie that figure to no specific table, as the studio does not either.
One hand at Rumba Blackjack 1, from bet to payout
An invented but rule-correct round:
- Betting window. The countdown opens; you place chips in your seat's box.
- Deal. Every player gets two cards face up; the dealer takes one up, one down. You get 10 and 6, a hard 16. The dealer's upcard is a 9.
- Insurance? Not offered, because the upcard is not an ace.
- Your turn. Hard 16 against a nine: no surrender, so basic strategy says hit. A four arrives — 20.
- Stand. On 20 you press stand.
- Dealer's hand. The hidden card is turned: an 8, for 17. Under S17 the dealer stands.
- Settlement. 20 beats 17; your bet pays 1:1.
Step 4 decided everything. In blackjack that moment is yours, not a wheel's.
Basic strategy extract: a generic 8-deck S17 chart
A generic, maths-based extract for 8 decks, S17, double after split, no surrender. Neither Dukat.bet nor Ezugi publishes it, and other rules change a few cells.
| Your hand | Dealer 2–6 | Dealer 7–9 | Dealer 10–ace |
|---|---|---|---|
| Hard 9 | double vs 3–6, hit vs 2 | hit | hit |
| Hard 10 | double | double | hit |
| Hard 11 | double | double | double vs 10, hit vs ace |
| Hard 12 | stand vs 4–6, hit vs 2–3 | hit | hit |
| Hard 13–16 | stand | hit | hit |
| Soft 18 (ace–7) | double vs 3–6, stand vs 2 | stand vs 7–8, hit vs 9 | hit |
| Ace–ace, 8–8 | split | split | split |
| 10–10 | stand | stand | stand |
No row asks for insurance. Playing from a cheat sheet is perfectly fine.
What a 3:2 payout is worth: an illustrative calculation
At the Rumba table a blackjack pays 3:2; some tables around the world pay only 6:5.
Illustrative calculation (not Dukat.bet data): on a 2,000 HUF stake, a 3:2 blackjack brings 3,000 HUF and a 6:5 one brings 2,400 HUF. Roughly one hand in 21 is a blackjack, so over 210 hands that is about 10 times: a 6,000 HUF gap on the same game.
At 99.50% RTP, a 1,000 HUF stake over 100 hands means an expected loss of about 500 HUF. That is an average; one evening can swing far either side. For pacing your rounds, see the session limits page.
What the blackjack tile in the lobby keeps quiet
The lobby shows a name and a studio; the rest turns up later, or never.
- The limit. Visible only on the open table; we do not publish it.
- The rule variant. Similar names can hide different rules; see the blackjack variants cards.
- The price of side bets. 21+3 and Perfect Pairs have an RTP well below the base game. See the side bets page.
Rumba and the other live card tables sit together under Dukat.bet live blackjack. Not every table carries the Blackjack tag, so if a name is missing, try the general live list.
Dukat.bet's general bonus rules, in point 2.14, leave live dealer play out of wagering. Whether the main live offer, the Live Casino Bonus – 500% up to 3,000 EUR + 15% Cashback, is different depends on its own terms, so read them before you stake. You must be 18 or older, and the stake should be money meant for fun.
