This does not happen very often.
In an incredible turn of events at Encore Boston Harbor, a fortunate gambler struck gold with a life-changing jackpot worth more than $606,654.
This unbelievable win occurred during a round of Super 4 Blackjack last month. It's a game known for its thrilling potential for massive payouts through its progressive jackpot feature.
The winning hand? A Royal Flush in Spades, triggered by a modest $5 side bet on the progressive jackpot.
The casino celebrated the win and announced it at the same time on its Facebook page.
This impressive win brings to mind a similarly thrilling victory achieved by an anonymous player at MGM Springfield. With just a $5 bet, this lucky individual struck gold in a game of Super 4 Progressive Blackjack, walking away with an astounding jackpot exceeding $250,000.
While this remarkable feat doesn’t quite surpass the massive Super 4 Progressive side bet win recently seen in Connecticut, it certainly stands out as a noteworthy and thrilling triumph within the realm of casino gaming.
A Closer Look at Super 4 Blackjack's Progressive Jackpot
Super 4 Blackjack is a popular side bet that adds an additional layer of excitement to the classic game.
Available at Encore Boston Harbor and numerous other casinos, the progressive jackpot feature rewards players with hefty payouts if they are lucky enough to achieve specific card combinations.
To participate, players place a $5 side bet in addition to their primary Blackjack wager.
Should the player's hand and the dealer's form a qualifying combination, such as a Royal Flush, the progressive jackpot is awarded. Following each win, the jackpot resets and begins to grow once more as players continue to place side bets.
Hitting a Super 4 Blackjack Progressive is Rare
The jackpot is primarily activated by rare hands, and its value escalates with each side bet placed until it is finally won.
In the case of this monumental October 2025 win, the jackpot was claimed with a Royal Flush in Spades, considered one of the highest-paying combinations in the game. The payout odds for a Royal Flush can vary depending on the suit and specific version of Super 4 Blackjack being played.
A Royal Flush in diamonds is the most valuable, winning 100% of the jackpot. If you get a Royal Flush in spades, hearts, or clubs, you win 10% of the jackpot. Even 10% can be a huge amount, as shown by this big win.
The chance of getting any Royal Flush in Super 4 Blackjack is very low, about 1 in 199,000. For a Royal Flush in diamonds, the chance is even lower, about 1 in 597,000. This makes these wins very rare and exciting.
