A New Year’s Day visit to Encore Boston Harbor in Everett, Massachusetts, turned into a historic event for a lucky gambler who hit a massive $1,620,355.70 jackpot. The win occurred on AGS’ Royal 9® Baccarat, fueled by the developer’s innovative STAX™ Progressive platform.
The payout is the largest single jackpot ever awarded in the history of the resort and potentially sets a new record for the state of Massachusetts.
The Winning Moment
The winner, identified as a man from Quincy, MA, who chose to remain anonymous, triggered the life-changing prize with a single $5 progressive side bet.
The Royal 9 Baccarat progressive adds a unique layer to traditional baccarat:
-
Personal King-Nine: Each seat at the table is assigned a unique, pre-printed King/Nine combination.
-
The Trigger: The top-tier jackpot is hit when both the Player and Banker hands perfectly match the specific King-Nine combination imprinted at the player’s seat.
-
STAX™ Platform: The win was facilitated by AGS’ STAX system, which allows for multi-level, “must-hit-by” jackpots and community prizes.
“We built STAX to bring incredible wins to players, and this is exactly the kind of excitement we envisioned,” said John Hemberger, SVP and General Manager, Table Games for AGS. “This is a true testament of what a single $5 progressive bet can do.”
