How to Play Triple 7 Inferno

Start by adding credits to the slot machine from your balance. Each credit is $1. Just click on the chip denominations (you’ll see $5, $25 and $100 chips) to add multiple credits, or click on the coin slot on the machine for single credits. You can add credits up to the full balance of your account.

Next, determine how many credits you want to bet, from 1-3. You can choose by either hitting the “Bet One” button up to 3 times, or hitting the “Bet Max” button. If you choose “Bet Max” you’ll bet 3 credits, and the machine will automatically spin without you hitting the “Spin Reel” button.

Now that you’ve placed a wager, just hit “Spin Reel” to play!

How to Win

Lucky 7 Inferno pays on a single line, marked “Payline” on the machine. Winnings depend on how many coins you play, and the Progressive Jackpot can be won if you bet 3 coins.

The story behind the game

Triple 7 Inferno is a throwback to historic slot machines from the infancy of Las Vegas, and even before. The first mechanical slot machine was the Liberty Bell, invented in 1895 by a car mechanic named Charles Fey. The grand prize for hitting 3 Liberty Bell symbols? Fifty cents.

Fey went on to create the Operator Bell slot, which featured the famous fruit design that is still popular in many slots today. His machines were popular for a time, until the arrival of anti-gambling movement that piggybacked on prohibition in the early 20th century.

Many years later, slot machines began the modern phase in their history at the hands of mobster and casino owner Bugsy Siegel. He used them to fill up space in his Flamingo Hilton and to, as he put it, keep the women busy while the men were at the tables. Slot machines proved wildly popular however, and were soon the dominant form of casino games in gambling. Today they provide up to 80% of revenue in the big Las Vegas casinos.

The Lucky 7 design, and later the Triple 7 Inferno, is based on the well known belief in 7 as a lucky number. The origins of this belief may go back to the Bible, and the holiness of the 7th day Sabbath. Later, the number took on extra significance for gamblers, especially craps players. On a roll of two dice, the number 7 can be made from the most possible combinations. As well, the opposite sides of dice always add up to 7.

Whether you believe 7 is a lucky number or not, you can enjoy some history, and a long tradition of good fortune, when you take a spin on the Triple 7 Inferno.


Pay Line: A line that shows where symbols have to land after the reels finish spinning, to award prizes.

Progressive Jackpot: A jackpot that gets larger and larger the longer it goes without being won.

Flameballs: These are the, well, flaming balls that cover some 7s on the reels. If 3 of them land on the pay line while you’re playing 3 coins, you win the massive Progressive Jackpot!
