Gravity Blackjack belongs to the ICONIC21 live game range. Its defining feature is the extra payout available when a winning side bet receives a multiplier. Main-hand decisions still involve familiar blackjack choices such as hitting, standing, doubling, and splitting.
The published rules describe an eight-deck game in which the dealer draws to 16 and stands on all 17s. Unlimited seating lets players join during an open betting window. An ordinary winning hand pays 1:1; a natural blackjack, an ace with a ten-value card in the initial two-card hand, pays 3:2.
The provider’s published game images show a main betting range of €1 to €5,000. Treat that as an example configuration: currency, side bet limits, and available stakes must be checked at the casino table you open. A maximum payout shown elsewhere in this review also depends on the qualifying side bet and its assigned multiplier.
The aim is to finish with a higher total than the dealer without going over 21. Number cards keep their face value, ten-value cards count as 10, and an ace counts as 1 or 11 according to the hand.
Insurance may be offered when the dealer shows an ace. It is an additional bet on the dealer having blackjack and pays 2:1 when it wins.
The four optional side bets use card combinations or the dealer’s final result. Their stakes are separate from the main blackjack stake.
This bet uses the player’s first two cards. A mixed pair has the same rank with one red card and one black card. A colored pair has the same rank and color but different suits. A perfect pair matches both rank and suit, which is possible in an eight-deck game.
Your first two cards and the dealer’s face-up card form a three-card poker combination. Qualifying results include a flush, straight, three of a kind, straight flush, and suited trips.
The published paytable includes any queen, a two-card total of 20, suited 20, matched 20, and a pair of queens of hearts. A queen is therefore not required for every winning category. Use the table’s Help panel to check category definitions and settlement.
This bet depends on the dealer going over 21. The paytable increases with the number of cards in the dealer’s bust hand. An eight-card-or-longer bust is the top category.
The published rules describe random side bet multipliers from 2x to 10x. The multiplier applies to the payout of the selected side bet when it wins. It does not boost an ordinary main-hand win or a natural blackjack. A highlighted multiplier by itself does not produce a payout.
| Pros | Cons |
|---|---|
| Unlimited seating supports a shared live table | Four side bets add separate rules and payout conditions |
| A natural blackjack pays 3:2 in the published rules | The advertised maximum payout requires a rare side bet outcome |
| All four side bets are optional | Adding side bets increases the total amount committed to a round |
| Random multipliers can increase qualifying side bet payouts | Multipliers do not increase the payout on the main blackjack hand |
| Main and side bet areas are clearly separated in the game layout | The published side bet RTPs are lower than the main game RTP |
| The game supports desktop and mobile access | Limits and availability depend on the casino and player location |
Use a basic strategy chart that matches the table’s exact rules. Check the number of decks, dealer behavior, doubling rules, and splitting rules before relying on a chart. Sound decisions can reduce avoidable mistakes, but they do not guarantee a winning session.
Our live blackjack tutorial explains the basic decisions used at the table.
For the decision tables and worked stake examples, read our Gravity Blackjack strategy and cheat sheet.
Search for Gravity Blackjack by ICONIC21 in your casino’s live game lobby. A casino carrying other ICONIC21 games may have a different catalog for your location, so check this exact title before depositing.
Confirm the operator’s license for your market, account eligibility, available currency, and current table limits. If you plan to use a bonus, read its eligible-game list, blackjack wagering contribution, maximum permitted stake, and side bet restrictions. Game availability and promotional terms can change.

The RTP table below follows the figures in the Hands & RTP section of Stake.us’s Gravity Blackjack description. These figures describe the published rules reference. We have not verified them against the current in-game Help, and ICONIC21’s public product page does not publish an RTP figure. Confirm the applicable main-game and side bet RTPs in the table you open.
| Bet | Published RTP | Implied house edge |
|---|---|---|
| Main blackjack game | 99.29% | 0.71% |
| Perfect Pairs | 95.95% | 4.05% |
| 21+3 | 96.38% | 3.62% |
| Lucky Ladies | 94.58% | 5.42% |
| Dealer Bust | 93.20% | 6.80% |
The main game’s theoretical return depends on the decisions assumed in its mathematical model. RTP describes an average over a very large number of wagers. It is not the probability of winning a hand or a promised return on a deposit. The house edge figures above are calculated as 100% minus the stated RTP.
Adding side bets changes the mix of wagers and the expected return on the total amount staked. No betting progression guarantees a profit or removes the house edge.
Set spending and time limits before playing. Never chase losses, and read our responsible gambling guidance.
The existing game images show a live dealer view, a central main betting area, separate side bet positions, and on-screen decision buttons. The table also provides game information and account-dependent controls through its menu.
Gravity Blackjack supports desktop and mobile play through participating casinos. Before wagering on a phone, check that you can read both hands, see the countdown, and distinguish hit, stand, double, and split. Use a stable connection and check the operator’s rules for interrupted rounds.
Spoken dealer language and interface language are separate settings. Changing the interface translates available controls and information; it does not change the language spoken by the dealer. Check the table lobby and language menu for the options available in your casino’s version.
Gravity Blackjack offers a familiar main game alongside four optional ways to bet on the cards. Its strongest distinction is the multiplier feature attached to the side bets, which creates larger potential payouts and more volatile results. The main game remains straightforward for readers already comfortable with blackjack rules.
The trade-off is the extra cost and complexity of the side bets. Their published RTP figures are lower than the main game’s reported 99.29%, and the largest payout needs a specific outcome with the maximum multiplier. Keep the total stake visible when comparing this table with other live blackjack games.

For this update, we compared ICONIC21’s product information with published operator rules and the existing game screenshots. These sources support the game format and the paytables shown here. A new real-money session, mobile performance test, and casino-by-casino availability check were not completed for this update.
The RTP section identifies the published rules figure and its scope. The table’s own Help and paytable should be checked before placing a bet, especially when an operator summary displays a different figure.
