On Aug. 2, an unnamed player at Encore Boston Harbor placed a $5 wager on a blackjack side bet and walked away with $38,028. The winning condition was a Royal Flush in Diamonds. The payout ratio implied by those two figures is roughly 7,600-to-1.

The Super4 Side Bet That Paid Out in Boston
According to MassLive, the win came through a product called Super4 Blackjack, a side bet offered alongside the main game in which players stake a separate wager on specific card combinations independent of their primary hand. The top payout tier requires a Royal Flush in Diamonds, a formation rare enough that the $38,028 prize speaks to its scarcity more plainly than any probability statement could.
Encore Boston Harbor did not release the name of the winning player. The resort’s gaming floor holds more than 175 table games and more than 2,700 slot machines, giving the property a large enough surface area that a single side-bet jackpot on one table registers as a footnote in aggregate terms, even if it is life-altering for the individual holding the cards.
The 7,600-to-1 implied ratio is not a house-edge figure; it is simply what the numbers show when a $5 input produces a $38,028 output. It conveys, without editorializing, how infrequently the top condition lands.
Croatian Tables Run the Same Math
The Geek.hr Team, a Croatian editorial team covering technology, science, and digital culture, follows developments in gaming markets as part of its broader beat on digital and consumer trends. From that vantage, the Super4 event reads less as a Massachusetts story than as a reminder of how portable these bet structures are.
Casinos in Croatia operate the same class of blackjack side bets under the same pay-table logic, meaning a Croatian player who places a bonus wager on a specific card combination faces volatility no different from what the Encore Boston Harbor outcome illustrates. The rarity of a Royal Flush in Diamonds does not soften at a different latitude. The evidence from the Royal 9 Baccarat progressive at the same Massachusetts resort, which spent weeks climbing past $1.6 million without producing a winner, reinforces the point. Long stretches without a top-tier hit are not a regional quirk; they are how these products are structured.
“The Royal Flush condition in the Super4 game is not a near-miss event. It is the kind of outcome that a side-bet pool can go months without producing, and the Boston Baccarat progressive showed exactly that pattern in real time. The math is the same wherever the table sits.”
A Baccarat Progressive That Climbed for Weeks Before Paying
The Royal 9 Baccarat jackpot at Encore Boston Harbor provides the clearest available window into how these top-tier progressive pools behave. The pot was already approaching $1.6 million in December and continued rising without resolution through the end of the month. A man from Quincy, Massachusetts finally hit the winning condition on New Year’s Day, collecting $1,620,335.70.
The prolonged accumulation period is not incidental. It is the mechanism. A jackpot that grows for weeks without paying reflects the underlying frequency with which the qualifying event occurs, and that frequency is a product of deliberate structural design, not variance or luck. Players who watch a progressive climb and interpret the growth as a signal that a hit is overdue are misreading how probability works: each hand is independent, and the pool’s size tells the player nothing about when the top condition will next appear.
The Record Month and the Casino’s Own Framing
Last August, Encore Boston Harbor set a record for jackpot payouts, distributing more than $46.3 million to winners across its gaming floor. That figure illustrates the aggregate scale at which a large resort operates, but it does not map onto any individual player’s experience. One player’s $5 bet did not benefit from the casino paying out tens of millions to others; those are separate transactions, separate hands, separate odds.
The casino’s own press release, issued after the New Year’s Day Baccarat win, described the result as a “record-setting win” that “adds to the excitement of the holiday celebration and underscores the thrill of high-stakes gaming at the resort.” The language is institutional and celebratory, as press releases from casinos reliably are. It positions the jackpot as evidence of what the venue offers rather than as a data point in how rarely the qualifying condition occurs.
That framing is not dishonest. A $1.6 million payout is genuinely extraordinary. But the Aug. 2 Super4 win, viewed through the same lens, is equally extraordinary in a quieter register: $5 in, $38,028 out, a Royal Flush in Diamonds, and no name attached to the player who held it.
The casino’s statement remains the last public word on the New Year’s Day event: “The record-setting win adds to the excitement of the holiday celebration and underscores the thrill of high-stakes gaming at the resort.“
