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.

Don’t break the law

Home haircuts are technically a felony, and so are all these small things

Image: Michał Jakubowski

Maybe you think of yourself as a law-abiding citizen who stays on the straight and narrow, but the truth is that the American legal system is full of weird rules that might catch you off guard. From honking without a real reason to cutting your partner’s hair, there are dozens of little things we do every day that could be considered a felony . Most of these laws were written a long time ago with good intentions, but they seem somewhat outdated today. Join us as we learn these offenses that could make an "outlaw" out of any common citizen.

1
Being annoying

Image: Andre Hunter

We all have bad days where our mood goes south, but in Florida, you’d better keep those frustrations to yourself . Ever since 1832, the Sunshine State has had a broad nuisance statute that classifies anything that "annoys the community, injures public health, or corrupts public morals" as a second-degree misdemeanor. Of course, the law was intended to address community hazards like toxic waste disposal or unsafe buildings. Modern enforcement targets environmental hazards and serious health violations. Personal annoyances are off-limits, since what qualifies as "annoying" is completely subjective.

2
Honking with no purpose

Image: Hitanshu Patel

We’ve all used our car horn to wave at a neighbor or used it to vent a little frustration in traffic. However, in New Jersey, according to their traffic code, your horn is legally reserved for safety warnings only . In this state, using it for any non-emergency reason is technically a traffic violation since 1968. Unless you are trying to prevent a fender-bender or warn a distracted driver, it is best to keep your hands off the steering wheel's center and just give a friendly wave instead.

3
Dangling car decorations

Image: Daniel Hobiera

If you have a pine-scented air freshener or a set of graduation tassels swinging from your rearview mirror, you might be looking at a ticket in some states. Laws vary across the country, but for example, in California, the law states that there cannot be anything obstructing the view through the windshield or side window . This rule is part of the California Vehicle Code, enforced in 1959. In Texas, the regulation is similar according to the state Transportation Code, and Minnesota, in turn, has had a law since 1957 making it strictly illegal to hang anything from the mirror. Nobody has anything against a nice-smelling car or a beautiful lucky charm, but when they obstruct your view , that’s a problem for everyone on the road.

4
Handling a stranger’s mail

Image: sue hughes

It’s not unusual to find a stack of letters addressed to the person who lived in your house three years ago, right? Now, your first instinct might be to toss it in the bin . Believe it or not, that’s a big no-no since 1948, clearly stated in the U.S. Code. Tossing out mail intended for someone else into the garbage is considered a federal felony, and penalties can be severe, including up to five years in federal prison and fines up to $250,000. The proper way to proceed is to write "refused" or "return to sender" on the envelope and let the post office take it from there.

5
Forgetting to tell the DMV you moved

Image: Erik Mclean

Life gets busy and messy when you move to a new house, so it’s easy for updating your driver's license to fall to the bottom of the to-do list. However, in most states, you are legally required to notify the DMV of your change of address within a very short window, usually ten to thirty days . In California, for example, you must do this within ten days. If you get pulled over and your license doesn't match your current address, you could get a fine. Time really flies when moving, but make sure to write this on the very top of your to-do list, and you’ll be fine!

6
Letting the engine on

Image: Carbyn Wu

Isn’t it common to start the car on a frosty morning to let it warm up while you finish getting ready? Well, if you do this, you’re technically breaking the law in some states: since 2004, in Ohio and Colorado, this is actually a citable offense known as "puffing." Leaving an unattended vehicle idling in your driveway is illegal because it invites car theft and contributes to unnecessary exhaust emissions. If you want to get the heater going, the law expects you to stay right there in the driver's seat until you’re ready to pull away.

7
Prank pizzas

Image: Mariya

In Louisiana, ordering a stack of pizzas to be delivered to an unsuspecting friend as a prank is more than just a lousy joke; it’s a crime. Believe it or not, there’s a reason behind this law. Passed in 2018, the Louisiana Revised Statute was specifically written to protect small businesses from losing time and money on fake orders. Can you imagine how annoying it must be to deal with a pranked customer who doesn’t want the five pizzas they got out of the blue? Even if it started as a joke, the authorities now view it as a form of theft that can result in a fine of up to $500, imprisonment for up to six months, or both.

8
Playing hairdresser

Image: Gabriela

If you’ve ever offered to give a friend a quick perm or some highlights in your kitchen, you might be an accidental criminal. In the US, performing any kind of cosmetology service on another person without a professional license is illegal. Forms of enforcement and penalties depend on each state, but most follow the rules established by the National-Interstate Council of State Boards of Cosmetology, which grants licenses following pertinent examinations. Of course, a bangs cut is not always a problem, but these kinds of regulations were created to ensure that chemicals and sharp tools are handled safely by trained experts.

9
No-hands bike riding

Image: Florian Kurrasch Disponible para contratación

Riding a bike is fun, especially for kids who like to do tricks and take both hands off the handlebars. But in North Carolina, that’s a traffic violation, according to the city code. The statute requires cyclists to keep at least one hand on the grip at all times to maintain control of the bike. Fines for this behavior can go up to $50 and even imprisonment for up to 30 days. Riding a bike without using your hands might feel like a fun way to show off skills, but the consequences can be serious.

10
Tossing out old batteries

Image: Syed Ahmad

When the remote dies, most people are tempted to just drop the old batteries into the kitchen trash can, but you might want to think that over, especially if you live in California. As of 2005, in this state, household batteries are classified as hazardous waste because they contain chemicals that leak into the soil. The California Rechargeable Battery Recycling Act requires you to take them to a proper recycling center instead of the regular landfill. It takes a little more effort to do the right thing, but it keeps the local environment a lot cleaner for everyone.

11
Lending your Wi-Fi password

Image: Dreamlike Street

You’ve just moved, and you ask your friendly neighbor to share their Wi-Fi password until your internet is set up. That’s pretty common, but that’s also been a felony since 1986. The feds view this as unauthorized access to a computer network . Under the Computer Fraud and Abuse Act, jumping on a signal you don't have explicit and formal permission to use is technically a crime. It’s better to stick to the local coffee shop than risk a run-in over a bit of borrowed bandwidth.

Have you experienced any coincidences?

12 incredible coincidences in American history

Image: Library of Congress

A coincidence is a remarkable concurrence of events or circumstances without an apparent causal connection. Most of us experience coincidences regularly, but they tend to be more ordinary—like discovering you’re wearing the same sweater as someone else in the room. The following 12 examples are much more extreme, and some even seem unbelievable, even though they are true. Read on and prepare to be amazed!

1
A Presidential curse

Image: David Everett Strickler

For almost 140 years, U.S. presidents elected in years ending in zero died while in office. It happened to William Henry Harrison (1840), Abraham Lincoln (1860), James A. Garfield (1880), William McKinley (1900), Warren G. Harding (1920), Franklin D. Roosevelt (1940), and John F. Kennedy in 1960 . Ronald Reagan, elected in 1980 , broke the curse by surviving an assassination attempt.

2
Mark Twain and Halley’s Comet

Image: Justin Wolff

In the year Mark Twain was born, 1835, Halley’s Comet passed by Earth. The great writer famously predicted he’d "go out with it" as well . Indeed, he passed away in 1910, the next time the comet appeared.

3
Jefferson and Adams

Image: iStrfry , Marcus

A patriotic yet somber coincidence, indeed. John Adams and Thomas Jefferson, the second and third U.S. presidents, both died on July 4, 1826 —exactly 50 years after the signing of the Declaration of Independence.

4
Hoover Dam’s first and last casualties

Image: Ryan Thorpe

The construction of the Hoover Dam was a long and difficult process, claiming over 100 lives. The first person to die was J.G. Tierney , and the last recorded death was his son , Patrick Tierney.

5
Lincoln and Kennedy

Image: Kelli Dougal

Abraham Lincoln and John F. Kennedy were elected 100 years apart (1860 and 1960). Both suffered fatal head wounds and were succeeded by presidents named Johnson. Their assassins each had three names: John Wilkes Booth and Lee Harvey Oswald. Both were assassinated on a Friday while sitting next to their wives at the time that it happened.

Actor Charles Francis Coghlan died in Texas in 1899. But his casket was lost at sea during a hurricane. Eight years later, his coffin washed ashore near his birthplace in Prince Edward Island, Canada, more than 3,000 miles away.

7
The Titanic coincidence

Image: K. Mitch Hodge

A few years before the Titanic sank, Morgan Robertson wrote a short book called Futility , about a massive "unsinkable" ship called the Titan that hit an iceberg and sank. The tale describes a ship with a similar size and a similar lack of lifeboats to the famous vessel.

8
Dennis the Menace

Image: Mitch Rosen

Two comic strips featuring a character named Dennis the Menace debuted in British and American outlets, respectively, on March 12, 1961—only a few hours apart. However, the two creators did not know each other and had no idea of the other’s work.

9
Jim Lewis and Jim Springer

Image: Vidar Nordli-Mathisen

Identical twin brothers separated at birth , Jim Lewis and Jim Springer, were reunited at age 39 and discovered many coincidences: both married women named Linda , divorced, and then remarried women named Betty. Both had dogs named Toy and drove the same model of car. Both grew up with an adopted brother named Larry and had sons whom they named James Allan.

A soon-to-be-married couple, Alex and Donna , were looking through old photos to include in their wedding video. They found one photo of Donna posing on a childhood trip to Disney World in 1980. And in the background, they spotted Alex being pushed in a stroller by his father.

11
Moped meets taxi, twice

Image: Ruslan Bardash

In 1975, 17-year-old Erskine Lawrence Ebbin was struck by a taxi in Bermuda while riding his moped. A year later, his brother Neville , also 17 at the time, was riding the same moped when he was struck by the same taxi —with the same passenger—on the same street.

12
Lightning strike survivor

Image: Felix Mittermeier

Being hit by lightning is an extremely rare occurrence. Park ranger Roy Sullivan was struck not once, but seven times between 1942 and 1977 —and survived them all. The strikes hit him in a fire tower, in his truck, in his yard, while patrolling, and more. His unusual record earned him the nickname "Human Lightning Rod."
