Encore Boston Harbor Casino had four customers hit it big playing small-stakes slots last week.

Two players won jackpots on slot machine within a few hours on March 22. The first player turned a $2 bet on the Huff N Puff Money Mansion machine into a very nice smack-a-rooney of $19,950.09. Casino staff responded to another machine going off like a fire truck the same evening when a player turned a $12.50 bet into $21,607.14 playing Lighting Dollar Link.

The two players got lucky picking the right machine at the right moment as Encore Boston Harbor Casino is the home to more than 2,700 slot machines, as well as 175 table games.

A day later, a patron turned a $7.50 bet into $25,548.64 on a Huff N Even More Puff Grand machine.

But they weren’t as lucky as the unnamed player who turned a $2.50 bet on the Screaming Links machine into $178,975 the same week.

The casino says that 13,635 were won there in February alone, paying out $36,420,957.87 in prize money, mostly off of the slot machines. This was the lowest amount the casino paid out in jackpots in seven months. In January, $40,699,671.04 was paid out by 14,895 total jackpots, while December saw $43,030,773.07 paid out by 16,147 total jackpots.

That amount includes the $1,620,335.70 an unnamed player won winning the progressive jackpot playing “Royal 9 Baccarat.”

In August, Encore Boston Harbor Casino says it paid out the most jackpots in its nearly seven-year history: $46.3 million.
