Sin City’s secrets

Fascinating facts about Las Vegas you won't find on travel guides

Image: Paul IJsendoorn

A man once sold every single thing he owned, flew to Las Vegas, and bet the whole lot on a single spin of the roulette wheel. Do you think he won? There are 600 miles of concrete flood tunnels under Sin City—can you estimate how many people live there? Most of the profits of the whole city come from one single game; could you guess which one it is? Read on to find all the answers to these stunning facts about Las Vegas, Nevada.

1
The man who sold everything he owned and bet it all on one spin

Image: Pavel Danilyuk

In 2004, a 32-year-old British man named Ashley Revell walked into the Plaza Hotel and Casino in Las Vegas and placed every dollar he had in the world on a single spin of the roulette wheel.

In the months before, Revell had sold his house in Kent, his BMW, his Rolex watch, his golf clubs, his electronics, his furniture, and every piece of clothing he owned. The grand total of his liquidated possessions came to $135,300 . He pushed the entire stack of chips onto red as the ball was already spinning. It landed on Red 7.

Revell walked away with $270,600, exactly double what he had come in with. He tipped the croupier $600 on the way out. The whole thing was filmed by Sky One for a reality mini-series called Double or Nothing .

Beneath the casinos, an estimated 1,500 people live underground

Below the glittering hotels and neon lights of the Las Vegas Strip runs a network of concrete flood drainage tunnels stretching roughly 600 miles beneath the city. Built in the 1990s to manage flash flooding in the Nevada desert, these tunnels have become an unofficial home for hundreds of the city’s unhoused residents.

It is estimated that between 1,200 and 1,500 people live there . Some residents have constructed makeshift shelters from plywood and salvaged metal deep inside the tunnels, occasionally just yards below the casino floors above them.

The tunnels pose serious dangers: flooding risk during desert rainstorms, extreme heat, and high rates of substance abuse. A network of nonprofits, outreach teams, and government agencies coordinates aid by providing the residents with essentials and offering them long-term case management, like treatment and housing placement.

Las Vegas has a literal black book of people banned for life

Image: BehindTheTmuna

Since 1960, the Nevada Gaming Control Board has maintained what it officially calls the List of Excluded Persons, better known as the Black Book. The original publication was a black-covered booklet held together with Scotch tape, listing eleven people deemed to have "notorious or unsavory reputations."

Most of the early entries were organized crime figures: Chicago outfit boss Sam Giancana; enforcer Anthony "Tony the Ant" Spilotro, whose violent exploits inspired Joe Pesci’s character in the film Casino ; and nine other mob associates. Anyone whose name appears on the list is permanently banned from entering any licensed gaming establishment in the state of Nevada.

Violating the ban is a gross misdemeanor under Nevada law. As of 2026, there are 37 names on the list. No one has ever successfully appealed their removal.

Strange casino rules: no clocks, no windows, no soft dice

Image: Elizabeth Ferreira

Las Vegas casinos are designed to keep gamblers at the tables as long as possible. Clocks are banned to distract players from the passing of time. Windows are eliminated so that they cannot tell whether it is noon or 3 a.m.

What’s more, Nevada law governs even the dice. The Nevada Gaming Control Board requires casino dice to be perfectly transparent so that no hidden weights can be concealed inside . Each die must be precision-manufactured to within 1/10,000th of an inch, with razor-sharp corners and edges showing no rounding whatsoever. They are inspected regularly and, in high-stakes games, replaced every eight hours of play to ensure consistent rolls.

5
The famous Las Vegas Strip is not actually in Las Vegas

Image: David Lusvardi

The stretch of Las Vegas Boulevard South that the world knows as the Strip does not lie within the city limits of Las Vegas. This is the area that’s home to Caesars Palace, the Bellagio, MGM Grand, the Venetian, Mandalay Bay, and dozens of other iconic venues.

Technically, it falls within an unincorporated community called Paradise , which is governed by Clark County rather than the city of Las Vegas. Paradise was deliberately established in 1950, when casino owners moved to avoid Las Vegas city taxes and regulations while continuing to trade on the city’s name and benefit from its infrastructure.

The city of Las Vegas actually begins further north along the boulevard, near the Stratosphere. Paradise covers approximately 54 square miles and has a residential population of around 220,000 people, which means it’s one of the largest and most densely populated unincorporated communities in the United States.

The Luxor’s sky beam is the most powerful artificial light on earth

Rising straight up from the apex of the black pyramid-shaped Luxor Hotel and Casino, the Luxor Sky Beam has been one of the most recognizable sights in Las Vegas since the hotel opened in October 1993. It is, by any measure, the most powerful artificial light beam on the planet. The beam is produced by 39 individual xenon lamps, each with 7,000 watts and roughly the size of a washing machine, focused through computer-designed curved mirrors into a single concentrated column.

Together, they generate an estimated 42.3 billion candlepower. On a clear night, airline pilots have reported seeing the beam from as far as 250 miles away. The total operating cost, confirmed by Luxor engineer John Lichtsteiner, is $51 per hour, of which $20 is electricity. That adds up to $480 a day only for lighting the signature beam each night —or $175,200 a year.

Las Vegas is home to the tallest observation tower in the US

Image: Dave Morgan

Standing 1,149 feet above the Las Vegas valley, the Strat Tower, officially rebranded from the Stratosphere in 2020, is the tallest freestanding observation tower in the US and the second-tallest in the entire Western Hemisphere, surpassed only by the CN Tower in Toronto at 1,815 feet. It is also the tallest building in Nevada and the tallest structure west of the Mississippi River.

At the top, the Strat offers four outdoor thrill rides, including one that dangles riders 64 feet beyond the edge of the building on a mechanical arm, over 900 feet above the ground.

Slot machines account for around 60% of all casino revenue

Image: Elizabeth Ferreira

Walk into any Las Vegas casino, and the first thing that surrounds you (and the loudest) is the rows of slot machines that line nearly every available wall and corridor. That layout is not a coincidence.

It is estimated that slot machines consistently generate approximately 60 to 65 percent of all casino gaming revenue in Nevada. There is roughly one operating slot machine for every eight residents of Las Vegas. Nevada law requires that video slot machines pay out a minimum average of 75 percent, though Strip machines in practice typically return 87 to 97 percent.

Casinos place the most visible, most tempting machines near entrances, elevators, and high-foot-traffic corridors , a placement strategy that has been studied and refined over decades. Despite the rise of poker rooms and sports betting in recent years, slot machines have remained the single largest source of gaming income in Las Vegas without interruption for more than half a century.

The gambling capital of the world does not sell lottery tickets

Image: Obi

Nevada is one of only two states in the entire United States that have no state lottery, the other being Utah. You cannot legally walk into a convenience store and buy a $2 scratch-off ticket.

The reason is straightforward and has nothing to do with moral opposition. Nevada’s gaming industry has lobbied persistently and successfully against a state lottery since gambling was first legalized in 1931, on the grounds that a government-run lottery would directly compete with casino revenues.

FedEx was saved from bankruptcy by a Las Vegas blackjack table

Image: Joshua Santos

In 1971, FedEx, then called Federal Express, was days away from collapse. Founder Frederick W. Smith had built the company on the revolutionary idea of overnight package delivery using a central hub-and-spoke air network, but the business was not working.

The company had roughly $5,000 left in its operating account. It was not enough. Facing what appeared to be the end, Smith flew to Las Vegas and sat down at a blackjack table. He gambled the company’s last $5,000 and turned it into $27,000, which was just enough to cover that week’s fuel costs and keep the planes in the air. The breathing room bought by that blackjack session gave Smith enough time to secure additional financing. Today, FedEx employs more than 500,000 people worldwide and is valued at over $60 billion.

American wisdom

You’ve heard these American idioms—but their true origins will shock you

Image: Meelika Marzzarella

From colonial times to the modern day, American idioms reflect how the country grew, fought, worked, and talked. From quitting cold turkey to the whole nine yards, these sayings captured the spirit of each era. Some came from the battlefield, others from the frontier or factory floor. But all of these expressions here earned a place in everyday speech—and they still tell a uniquely American story.

1
Manifest Destiny

Image: Wayne Hollman

(1840s – Westward Expansion)

Coined in 1845 by journalist John L. O’Sullivan, "Manifest Destiny" justified America’s push westward, claiming it was the nation’s divine right and duty. Though sometimes controversial, it shaped the national mindset and defined 19th-century American expansionism.

2
Talk turkey

Image: Tyler Donaghy

(1800s – Rural America)

"Talking turkey" originally meant speaking plainly, especially during trade or bargaining sessions around Thanksgiving time. The phrase evolved from settlers' interactions with Native Americans and each other.

3
The whole nine yards

Image: Museums Victoria

(1940s – WWII era)

This phrase likely originated in World War II aviation. Fighter pilots reportedly gave "the whole nine yards" when they unloaded all their ammunition —about 27 feet of bullets. It now means going all out, and its roots in wartime tales made it a lasting piece of American lingo.

4
Cold turkey

Image: Andres Siimon

(1920s – Prohibition era)

"Cold turkey" first emerged in drug withdrawal circles during the 1920s, describing a sudden and complete stop, often painful and abrupt. It became more widespread during Prohibition, when people abruptly quit drinking.

5
Pull yourself up by your bootstraps

Image: Nathan Dumlao

(1930s – Great Depression)

Originally a sarcastic quip about doing the impossible, the phrase took on a new life during the Depression, urging Americans to self-rely and push through adversity. By WWII, it had become a proud motto for working-class Americans.

6
Loose lips sink ships

Image: John Kostyk

(1940s – WWII propaganda)

Created by the U.S. Office of War Information, this saying warned citizens and soldiers against careless talk that might aid enemy spies. It was one of the most effective propaganda slogans of WWII.

7
Duck and cover

Image: Stephen Cobb

(1950s – Cold War drills)

Coined in a 1951 civil defense film, this phrase taught schoolchildren to seek shelter from nuclear blasts. While its actual effectiveness was debatable, "duck and cover" captured the anxious era of nuclear tension. It’s since become shorthand for futile emergency preparedness.

8
Jump on the bandwagon

Image: Museums of History New South Wales

(19th century – American politics)

Originating in the 1848 campaign of circus showman Dan Rice, politicians literally used bandwagons to draw crowds. The term evolved as others "jumped on" to align with the popular cause. It now refers to any late but enthusiastic adoption of a trend.

9
Cut to the chase

Image: Jeremy Yap

(Hollywood – silent film era)

Early films often built up slowly, so impatient viewers and editors began saying, "cut to the chase" —the action scene. Now it means getting straight to the point.

10
Put a sock in it

Image: Denny Müller

(1920s – Gramophone era)

Before volume knobs, people muffled early gramophones by stuffing socks in the horn. The phrase quickly became slang for "be quiet."

America’s past

Grab a root and learn some interesting Civil War Lingo!

Image: Erika Wittlieb

The Civil War wasn’t just cannons and cavalry. It was also a time when soldiers invented a whole dictionary. Some terms were funny, some grim, and others quite practical. Today, we’ll peek into the soldier’s vocabulary , from "fresh fish" rookies to the itchy reality of "graybacks." So pull up a chair, maybe grab a root, and let’s take a trip through the words that marched alongside history.

1
Fresh fish

Image: Chris Chow

If you were new to the army , you were "fresh fish." Veterans spotted them a mile away, wide-eyed, uniforms still smelling like the depot, and not yet hardened by camp life. They got teased, trained, and sometimes tricked. Of course, every seasoned soldier once wore the "fresh fish" badge, so the teasing came with a knowing grin.

2
Grab a root

Image: Lars Blankers

Dinner time in camp could mean beans, hardtack, or, if you were lucky, a potato. Asking someone to "grab a root" was soldier shorthand for "let’s eat." Potatoes were cheap, filling, and easy to cook over a campfire.

3
Sawbones

Image: Piron Guillaume

Medical science in the 1860s wasn’t exactly what we call gentle. Army surgeons were nicknamed "sawbones," partly for their skill with amputations, a normal procedure during wartime. It wasn’t always fair, since many doctors were dedicated and resourceful, but the name stuck.

4
Graybacks

Image: Scott Umstattd

Ask a soldier about "graybacks" and you might get two very different answers. One was lice, the pest that thrived in crowded camps. The other was a nickname Union troops used for Confederate soldiers . Either way, it wasn’t a compliment.

5
Bonnie Blue Flag

This was the hit song of the Confederacy , praising the states that left the Union. The "Bonnie Blue Flag" itself showed a single white star on a blue field, the first banner of the Confederacy. The song’s lively chorus made it a favorite at rallies, campfires, and any place soldiers needed a boost of spirit.

6
Furlough

Image: Stijn Swinnen

A furlough was a soldier’s golden ticket home , even if only for a short while. The paperwork described the soldier’s looks, regiment, and exact return date, plus a stern warning about being labeled a deserter if he didn’t show up on time.

7
Housewife

Image: Annie Spratt

Every soldier carried a "housewife," though it wasn’t a person; it was a sewing kit . Packed with needles, thread, and spare buttons, it kept uniforms in one piece. With supply lines stretched thin, a quick stitch could mean the difference between looking like a soldier or a scarecrow.

8
Insult

Image: Aleksey Kashmar

On a Civil War battlefield, an "insult" wasn’t words, it was a sudden attack on a fortified position. The idea was to strike before the defenders could react. Success could turn the tide of a fight, but failure usually meant heavy losses. It was risky and brutal.

9
Kepi

Image: Jen Theodore

The kepi was the go-to cap for Union soldiers, with a flat circular top and short visor . It was light, practical, and easy to make, so it became part of the classic Civil War look. Confederate soldiers sometimes wore them too, but it was a Union signature item.

10
Ordnance

Image: Rick Lobs

If it was in any way designed to make the enemy’s day worse, it was "ordnance." This covered everything from muskets to cannonballs . Armies guarded their ordnance like gold, since running low meant fighting at a disadvantage.

11
Skirmish

Image: Carol Highsmith's America

Not every fight was a massive battle. A "skirmish" was a smaller clash , often between scouting parties or outposts. Quick, unpredictable, and sometimes over in minutes, skirmishes kept soldiers on edge and commanders guessing what the enemy was really up to.
