What is Live Quantum Blackjack Plus?

Live Quantum Blackjack Plus is an enhanced, one-to-many live dealer game, built on the familiar foundations of 21. It works by using a six-deck shoe, and the main feature is the multiplier mechanic. This means before the deal, three or five cards are randomly assigned multiplier values ranging from x2.5 up to x50. 

If your winning hand contains one of these multiplier cards, your payout is boosted accordingly, potentially reaching a massive 50x your wager. Standard rules largely apply, with blackjack paying 3:2. There is unlimited seating, which means all players receive the same hand, but make independent in-game decisions. 

One of the game's unique rules is the dealer’s three-card bust push. How this works is that if the dealer busts with exactly three cards, all standard bets push. This is unless your hand contains a multiplier card, in which case you win the multiplied payout.

    When choosing a casino site, ensure they hold a UKGC license to guarantee your safety and that they also offer responsible gambling tools such as deposit limits.

    Rules & Core Mechanics

    The gameplay cycle starts by placing your main stake and any optional side bets. Next, three or five random cards are assigned their multipliers. The deal then proceeds as normal. You must employ independent decisions such as Hit, Stand, Double, or Split. The dealer then plays out their hand, drawing until they reach a score of 17 or more.

    The multiplier cards add together and apply only if they are part of your final winning hand. Remember the unique blackjack push rules where a dealer’s three-card bust results in a push, unless you have a multiplier card, in which case you win based on the multiplier. Payouts for multiplied wins are expressed as net winnings (payout minus original stake).

    Side Bets & Multipliers

    Quantum Blackjack Plus features two optional side bets: Perfect Pairs and 21+3, and note that these are placed independently of the main game action, and multipliers do not affect their payouts.

    Side BetDescriptionExample PayoutApprox. RTP
    Perfect PairsYour first two cards form a pair (suited, coloured, or red/black)Up to 25:193.89%
    21+3Your first two cards plus the dealer’s up-card form a poker hand (e.g., Flush, Straight)Up to 100:195.38%

    The multipliers are assigned to three or five cards, which are randomly selected each round. They are given values of x2.5, x3, x5, or x10, and these multipliers only benefit your main bet payout if the card is part of your final winning hand. 

    Betting on side bets inherently increases variance and lowers your overall effective return, compared to optimal main game play.

    RTP, House Edge & Payouts

    The headline Quantum Blackjack Plus RTP is approximately 99.57% when employing optimal strategy on the main bet. This translates to a house edge of only about 0.43%, which is excellent for a live casino variant, provided you stick to the base game. Regular wins pay even money, and a standard blackjack pays 3:2. 

    Multipliers can boost these payouts significantly; for instance, a 5x multiplier on a 3:2 blackjack win provides a massive return, though remember your original stake is excluded from the displayed multiplied amount. 

    Conversely, the side bet RTPs are substantially lower, around the 94-95% mark. RTP is calculated over millions of hands and does not guarantee short-term results.

    Quantum Blackjack Plus Strategy & Tips 

    Basic blackjack strategy still applies for optimal play, but players should make minor adjustments due to the multipliers. The general advice holds, and that’s to hit on totals of 8 or below, stand on 17+, and double on 11. 

    However, you should note to exercise caution when you hold a multiplier card, as taking another card risks busting and losing the multiplier’s benefit entirely. If you hold a significant multiplier on a marginal hand, leaning towards standing might be the wiser, albeit less standard, play. Budgeting for side bets is important as well, so treat them as high-variance extras and wager smaller amounts relative to the main bet. 

    The unique dealer push rule means you occasionally lose winning potential on a standard win, but you also avoid losing if you would otherwise have busted. Always use responsible gambling tools like setting deposit limits and time-outs, and know where to find help via GamCare if needed.

    Quantum Blackjack Plus vs Other Blackjack Variants

    Quantum Blackjack Plus differs from Classic Live Blackjack by introducing the random multiplier layer, offering a higher win potential at the cost of increased volatility. So compared to Infinite Blackjack, which offers unlimited seats but fixed rules, the Quantum version of this game adds the multiplier feature. 

    Power Blackjack shares the multiplier concept but uses a 'Power Bet' feature instead of randomly assigned cards, changing the strategic focus significantly. Variants like Lightning Blackjack use a similar mechanic, but Quantum’s unique 3-card bust push rule offers a distinct defensive advantage when holding a multiplier. 

    We reckon that Quantum suits players who enjoy the standard ruleset but crave a bigger, intermittent payout boost without the structural commitment of an added 'Power Bet' or the high variance associated with some Lightning games.

    SportsBoom Suggests

    For the discerning UK live casino player who respects the high returns of classic blackjack but desires an adrenaline shot, Quantum Blackjack Plus is highly recommended by us here at SportsBoom. 

    You can play it as a hybrid and focus on optimal basic strategy for the main bet to leverage the exceptional RTP, and limit side bets to small, fun wagers. But as always, just make sure that you use responsible gambling tools, as there are no guarantees of winning.

    FAQs

    How does the multiplier mechanism work?

    Randomly, 3 or 5 cards each receive a multiplier (x2.5 to x10), and if your winning hand contains one or more of these cards, the multipliers are summed and applied to your standard payout.

    What is the RTP of Quantum Blackjack Plus?

    The main game RTP is approximately 99.57% when played with perfect basic strategy, and side bets have a lower RTP, around 94-95%.

    What happens if the dealer busts with three cards?

    If the dealer busts on exactly three cards, standard main bets push, but if your winning hand contains a multiplier card, you win the multiplied payout instead of pushing.

    What side bets are available, and are they worth it?

    Perfect Pairs and 21+3 are available, and they are generally not worth it for strategic players as they significantly lower the effective RTP compared to the main game.

    How do I play Quantum Blackjack Plus in the UK?

    You must register at a UKGC-licensed casino that features Playtech live games, make a deposit, and locate the table in their live lobby.

    Is Quantum Blackjack Plus rigged?

    Playtech is a reputable casino game provider, and all of their games on UKGC-licensed sites are regularly audited for fairness, and the randomness is governed by certified RNG systems.

    Can you apply card counting or another basic strategy when playing Quantum Blackjack?

    Basic strategy is necessary to maximise the high RTP, and card counting is significantly less effective than in shoe blackjack due to the "one-to-many" format and dealer play mechanics.
