What is rolling a 7 in craps?

Hey friend! As a fellow gaming enthusiast, let‘s dive deep into the dice game of craps and the mystical lucky number 7. Buckle up for a wild ride through theprobabilities, superstitions, and lingo around rolling 7s!

First, a quick history lesson. Craps traces its origins back to the 12th century, when European knights played a dice game called Hazard between battles. It evolved into a version called Crabes in old English gambling dens. When the game later crossed the Atlantic, it became corrupted into the name we know today.

Now let‘s break down the basics. In craps, players wager on the outcome of two six-sided dice rolled by the designated "shooter." If a 7 or 11 is rolled on the initial "come out" roll, pass line bets win. If a 2, 3, or 12 is rolled, pass line bets lose. Any other number becomes the "point" target number. The shooter then rolls again, trying to hit the point before rolling a 7 to win. If a 7 comes first, the pass line bets lose in what‘s known as a "seven out".

So clearly the 7 holds major power in craps! Here‘s why:

Why Does 7 Have the Most Impact?

• There are 6 different dice combinations that add up to 7 (6+1, 5+2, 4+3, 3+4, 2+5, 1+6).
• This makes rolling a 7 have a probability of 16.67%, higher than any other total.
• Other numbers only have 1-3 possible dice combinations, and lower probabilities.
• With more ways to make 7, it comes up more often – giving the house a built-in edge.

In fact, let‘s compare the probability percentages:

As you can see, 7 dominates the probability ratio – making it the pivotal number for pass line bets.

Now let‘s walk through some full craps gameplay scenarios to see the 7 in action:

Scenario 1 – Lucky Seven Out

• Shooter comes out and rolls a 6 to establish the point
• On their next 3 rolls, they hit 6, 8, then 4
• On the 5th roll after establishing the point, a 7 is rolled
• The pass line bets lose due to the shooter "sevening out"
• The dice move to the next shooter

Even though the shooter was hitting other numbers after the point, that eventual 7 meant an instant loss.

Scenario 2 – Seven on the Come Out

• Shooter comes out and rolls a 7 on the come out
• The pass line bets immediately lose
• No point is established
• The 7 came too soon!
• The dice pass to the next shooter

When 7 shows up on the come out roll, it means an instant loss for pass line bets.

Scenario 3 – Repeating Points

• Shooter establishes a point of 6
• They roll 6 again, repeating the point
• On the next rolls, they hit 8, 9, 5
• Finally a 7 is rolled, pass line bets lose

Here the shooter was lucky to keep hitting the point of 6 to avoid sevening out sooner.

While craps revolves around chance, let‘s discuss some ways players try to shift the odds related to rolling 7s:

Betting Strategies Around Rolling 7s

• The Fire Bet – This requires the shooter to hit points in a specific order before rolling a 7. Harder to do, but higher payouts.

• Laying the Odds – Betting extra on the points of 6 or 8 can lead to bigger wins when 7 inevitably rolls.

• Red Die Strategy – Some only bet when the red die is the point, thinking it results in more 7s rolled.

• Dice Setting & Control – Controversial technique of carefully throwing the dice to try reducing 7 frequency.

Even with these approaches, craps still comes down to luck!

Beyond the odds, rolling a 7 also carries cultural significance…

The Lucky 7 Mystique

Across cultures, 7 has always been viewed as a mystical lucky number:

• There are 7 days in the week. The 7th day, Saturday, is seen as a day of rest.

• Many religions describe 7 as a holy, spiritual number.

• 7 is seen as lucky in numerology and astrology.

• 7 is the most commonly rolled number on dice, enhancing its lucky allure.

No doubt thanks to its lucky reputation, 7 elicits a lot of superstitions at the craps table:

• Never say the word "seven" out loud – it might jinx the shooter!

• "Big Red" and "Midnight" are popular nicknames used instead of saying "seven" or "twelve".

• Shooters blowing on dice before rolling is thought to reduce 7 frequency.

• Pointing or gesturing at the dice is seen as bad etiquette, risking more 7s.

And when the 7 does inevitably roll in craps, you‘ll hear colorful lingo and slang:

• "7 out!" – Common call when a 7 rolls, ending the round.

• "Eighter from Decatur" – Creative term used instead of calling out an 8.

• "When a 7 is rolled, it‘s a ballgame over!"

• "Oh snap, the dealer rolled snake eyes!" – Slang for landing a 7 via double 1s.

As a craps aficionado, I‘ve certainly said my share of 7-related exclamations over the years. That‘s part of the excitement!

For a game revolving around just two dice, craps incorporates some fascinating history, statistics, and culture related to the almighty 7:
