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.

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.

8
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.

They have rules too

The president can’t open the White House windows? Here’s why!

Image: Fine Photographics

Being the president of a nation might seem glamorous, and while it comes with a couple of nice benefits, the role is also full of obligations, strict protocols, and surprising restrictions . From accepting luxurious gifts to buying a smartphone or taking a simple walk, here are all the "don’ts" of being a US president!

1
Open the windows

Image: Braden Burson

Yes, you read that right. A sitting US president can’t just get up and open the windows of the White House to enjoy a beautiful day. While there’s no law against it, the protocols state that any action that could pose a security risk to the commander-in-chief must be carefully reviewed and approved by the staff.

2
Go to the cinema

Image: Krists Luhaers

Going to the movies is one of life’s simple pleasures. Unfortunately, if you’re the president, it’s not one of your options. While it’s not officially forbidden, crowded and dark spaces like movie theaters represent serious security risks. Luckily, the White House has its own private screening room, so the president and his family can still enjoy movie night at home.

3
Attend their children’s events

Image: Sincerely Media

You’ll rarely see a president at their kids’ school plays or sporting events. And it’s not because they’re bad parents; it’s because regulations discourage them from attending. With so many people, children, and things happening at the same time, keeping the commander-in-chief safe in those settings is nearly impossible.

4
Buy their own tech devices

Image: appshunter.io

When a new iPhone hits the market, many rush to buy it, but presidents can’t make this decision on their own. Any electronic device, like a smartphone or tablet, could be vulnerable to hacking or espionage. So while presidents can use cell phones, theirs must be secure, vetted, and government-approved.

5
Block people on social media

Image: Julian

And that isn’t the only restriction on cell phones. Presidents who use their social media accounts for official communications are advised not to block people in their official POTUS account, since doing so could be seen as suppressing free speech. On the other hand, they can block users on personal accounts.

6
Go out alone

Image: Warren K. Leffler, Public domain, via Wikimedia Commons

The US president can’t just grab the keys and head out for a walk. Sure, strolls around the White House gardens are fine, but stepping beyond the gates is a different story. Anytime the president leaves the White House, even for a quick walk around the block, the Secret Service must secure the area, plan the route, and provide constant protection. Sounds a little overwhelming, right? But when you’re the commander in chief, safety always comes first!

7
Drive

Image: Jerry Kavan

Ever felt the urge to hop in your car and drive somewhere spontaneously? Well, if you’re the President of the United States, that’s off-limits. Security measures strongly recommend that presidents must always travel in a secure vehicle with a driver and a full security detail. In fact, the last president known to drive alone on the open road was Lyndon B. Johnson (1963-1969).

8
Fly on commercial airlines

Image: The White House, Public domain, via Wikimedia Commons

Just as security protocols strongly discourage the president from driving alone on open roads, flying on commercial airlines is also off-limits. Imagine being hundreds of feet in the air, locked in with strangers; it could be extremely unsafe when you’re the president of the United States. Implementing proper security measures would be too complicated, and with a large presidential staff, there might not even be enough seats for everyone.

9
Accept expensive gifts

Image: Ayana Ames

Presidents receive many, many letters and gifts from the public, but not all of them can be accepted. The US Constitution and federal law require presidents to decline overly expensive gifts, whether they come from foreign leaders or everyday citizens, to prevent any appearance of conflict of interest or corruption.

10
Discard official mail

Image: Wolfgang Vrede

Although it may seem like a harmless, ordinary task, the president can’t just start cleaning out their office or email inbox. All presidential correspondence, physical or digital (even spam!), is considered official government property. It must be processed or archived according to federal records regulations, and discarding anything requires a strict review process.

Yes, that was normal

These old childhood rules and traditions would shock parents today

Image: Rohan Mathur

There was a time when childhood looked very different. Often unsupervised, kids would roam, explore, improvise, and occasionally scare their parents half to death. Cultural norms have changed, and many of the routines and traditions that once defined the all-American childhood now seem reckless . Let’s look at some of them and see how drastically things have changed.

1
Leaving with your bike in the morning and coming back for suppertime

Image: Carl Tronders

For a few generations of American kids, a bicycle meant freedom. From the 1940s through the 1980s, children often left home after breakfast with little more than a vague instruction: "Be back before dinner."

Neighborhoods were informal safety nets, and kids were free to navigate them without phones or GPS trackers.

2
Foraging fruit from neighbors’ yards

Image: Libby Penner

It was a risky gamble: Picking and eating fruit from unknown plants in your neighborhood could result in a yummy treat…or abdominal trouble.

There was a time when kids freely grabbed berries, apples, or other fruit growing along sidewalks or in neighbors’ gardens. Today, property boundaries have grown, and kids are reminded not to forage without permission.

3
Riding public transportation alone

Image: Vitolda Klein

For much of the 20th century, it wasn’t unusual for children as young as 7 to ride buses, subways, or streetcars alone, especially in large cities like New York, Chicago, and Boston.

Kids commuting to school independently was considered a practical life skill. Parents expect children to learn responsibility through real-world experience , handling routes, change, and unexpected delays.

4
Roller coasters had no belts and no headrests

Image: Tore Odiin

Do you have memories of rickety rollercoasters? You might correctly remember that earlier rides were thrilling in ways that might give modern safety inspectors pause.

Many of the rides made popular in the 50s relied primarily on simple lap bars and operated with minimal restraints. Designers assumed riders would hold on tightly. Safety rules have evolved drastically since then, and now we have over-the-shoulder harnesses and improved lap restraints.

5
Walking miles to a friend’s house alone

Image: Ansis Kančs

Kids routinely walked long distances across neighborhoods or even between towns without adult accompaniment, guided by landmarks and memory. While this independence helped build confidence, it also reflected a different perception of risk.

6
Not ringing the bell: just yelling your friend’s name from outside

Image: the blowup

Before texting "I’m here" or coordinating playdates through apps, kids often announced their arrival the old-fashioned way: by standing outside and shouting a friend’s name.

Front yards, sidewalks, and porches acted as social hubs where everyone recognized familiar voices. As concerns about privacy, safety, and structured schedules grew with the years, the casual shout-from-the-street culture slowly disappeared.

7
Spending long days at the beach without adults

Image: Gaëtan De Cuyper

Surf culture in places like California and Hawaii, as well as East Coast boardwalk towns, normalized groups of kids swimming, riding the waves, and returning home only at sunset.

Public beaches were seen as community environments where lifeguards and familiar locals provided informal oversight . Today, increased safety standards, liability concerns, and changing parenting norms mean most children visit beaches with close adult supervision.

8
Exploring woods alone

Image: Joshua Earle

Few children who lived near a forest or rural area could resist the pull to explore it, either alone or with friends. Building forts, climbing trees, and learning their way around nature were influenced by scouting movements and postwar ideas about resilience and independence.

Psychologists today even describe this kind of unstructured outdoor play as beneficial for creativity and risk assessment skills. However, modern concerns about safety, traffic, and environmental hazards have reduced opportunities for unsupervised exploration.

9
Staying home alone or being babysat by older siblings

Image: Kelly Sikkema

The rise of the "latchkey kid" became especially visible in the United States during the 1970s and 1980s, when increasing numbers of dual-income households, or single-parent homes, meant children returned home from school to empty houses.

Many kids carried house keys, prepared snacks, and entertained themselves until their parents finished work. Today, research on changing childhood independence shows that unsupervised play and autonomy have significantly declined compared to previous generations.

10
Collecting glass bottles for some cents back

Image: Lacey Williams

Long before recycling bins appeared on every curb, kids learned about value through bottle returns. Soda and milk bottles carried deposits, and children would collect empties from their own homes or even from neighbors to trade for a few coins at local stores.

It was a first taste of earning money independently, although it often funded candy purchases or comic books.

11
Climbing trees or rooftops, unsupervised

Image: Victória Kubiaki

When you are a kid, climbing a tree is decidedly an adventure. There was a time when this was considered a universal childhood activity in America, even encouraged as a playful challenge, since mid-century parenting often embraced manageable risk.

But current safety standards and greater awareness of injury risks have dramatically reduced these kinds of unsupervised play environments.

12
Casually hanging out in abandoned buildings

Image: Ljubica

Another tempting area for children happened to be empty lots, half-built structures, and abandoned buildings . It was difficult to keep out curious and brave kids. This pastime is not entirely eradicated today, although it seems to be teenagers or young adults who engage in it.

13
Riding in cars without seatbelts

Image: Anton Luzhkovsky

For decades, families piled into cars without buckling up, simply because seatbelts weren’t standard equipment. Although basic seatbelt designs existed earlier, widespread adoption didn’t begin until the late 1950s and 1960s.

Even then, many Americans resisted using them, seeing belts as unnecessary or uncomfortable . Laws requiring seatbelt use didn’t become common until the 1980s and beyond, meaning generations of kids grew up riding freely in the back seat.

14
Playing in flooded streets after a storm

Image: Ayla Meinberg

Children once treated flooded streets like temporary playgrounds. Heavy rain expanded the available activities for a suburban child. They could splash barefoot through puddles or float makeshift boats down rushing gutters.

Over time, public health campaigns highlighted dangers such as contaminated runoff, hidden debris, electrical hazards, and traffic risks. Enough to scare modern parents!
