What does red light mean in a casino?

Hey friend! Have you ever walked through a busy casino and noticed those colorful lights all over the slot machines? If you‘re like me, those flashing lights are part of what draws you into the exciting casino environment. But beyond being eye-catching attractions, the lights on slots and other casino games actually communicate valuable information that savvy gamblers can use to their advantage.

In this guide, I‘ll decode the meaning behind common casino lighting elements so you can approach your next casino trip like a pro. With the inside scoop on these light signals, you‘ll boost your gambling strategy skills. Let‘s dive in!

A Quick History of Casino Game Lights

Gaming equipment wasn‘t always chock full of lights like we see today. Primitive poker and blackjack tables from the 1800s relied on candles and kerosene lamps for illumination. More advanced table games incorporated electric bulbs by the early 1900s. Slot machines also started with very basic lighting.

The first patented slot in 1891 called the "Liberty Bell" had no lights at all! This purely mechanical device was made of cast iron and featured physical reels that spun. It paid coins directly from the machine‘s interior. Later models like the Mills Liberty Bell in the 1910s added electric lights solely for decoration.

It wasn‘t until the 1960s that lights served functional purposes. Electromechanical slots with backlit reels and win indicators introduced more practical lighting. Today‘s fully electronic slots take this to the extreme with hundreds of intelligent LED lights across the play surfaces.

Modern casino game lighting has come a long way since the days of kerosene and hand-cranked reels! Next let‘s break down key light locations on contemporary equipment.

The Main Lighting Zones on Slot Machines

If you glance at any multiline video slot machine on a casino floor today, you‘ll notice bright lights positioned in clusters around the unit. These lights aren‘t just for show – their locations relate to specific functions. Check out the main lighting zones:

Top Box

This is the section that sits above the reels containing the game‘s title screen and decorative elements related to the theme. For example, an Egyptian treasure-themed slot would have pyramid shapes and hieroglyphics graphics.

Lights in this upper section usually flash randomly and change colors to grab your attention from a distance. The vibrant top box basically acts like a small billboard marketing the game.

Belly Glass

Below the spinning reels you‘ll see a horizontal pane of glass artwork, spanning the front of the machine. This panel is called the belly glass or glass.

Backlight illumination makes the images and text glow to stand out. Sections of the glass might light up independently to highlight game instructions or the pay table showing payouts for winning combinations.

Candle

Perched on top of most slots is a tall, thin cylinder containing a stack of lights. It‘s called a candle, but not because it has a flame!

The name candle comes from original mechanical slot machines in the 1920s that used actual candles as status indicators. Of course today‘s candles are electric. Let‘s look at what the different candle lights mean.

Candle Colors and What They Signal

Out of all the lights decorating modern slot machines, the candle conveys the most useful info for players. Checking the candle before choosing a game provides an advantage.

White

The top light on the candle is always white. When lit, it means the machine is turned on but hasn‘t been played since the last drop.

In casino jargon, the drop refers to slot attendants periodically collecting stored cash from the machines. If white is lit, that slot‘s coin tray is empty, primed for you!

Colored

The bottom candle light is colored – usually red or yellow. This indicates the machine‘s denomination, such as 1¢, 5¢, 25¢ credits. Red is for lower denominations, while yellow designates higher quarters and dollars.

Flashing

A flashing candle signals some kind of issue with the game. The attendant base needs to be contacted. A flashing white light specifically means a slot technician‘s help is required.

Alternating

When the two lights rapidly alternate back and forth between colors, that means a jackpot or large win has hit. This alerts staff to come over and process tax paperwork for the lucky winner.

No Light

An unlit candle simply means the slot is either powered off, or it‘s currently in use by another player. Once they finish that gaming session, the candle will turn on again.

Using the candle colors to find freshly reset games or denominations you prefer really maximizes your slot machine odds!

Other Helpful Lights Around the Slot Machine Face

In addition to the candle, various other lights across the play surface can provide useful clues:

• Bet lights – Small LEDs beside each bet button show the current wager selected.

• Payline lights – Indicators that flash along active winning paylines after a spin.

• Service light – A hidden notification (usually red or blue) that there‘s a technical fault needing repair.

• Tower light – A tall vertical bar with color bands used instead of a candle on older slots.

• Winner light – Separate flashing light for mega jackpot wins to attract a crowd.

Savvy slot players keep their eyes peeled for all these signals!

Light Meanings on Table Games and Poker

Lighting in casinos isn‘t limited to just slot machines, of course. Let‘s look at indicators used on other popular games:

Roulette

• Green light – Signals betting round is open and players can place chips.
• Red light – Indicates betting is closed, and wheel is spinning.
• Flashing lights – Computerized roulette wheels have lights around the winning number.

Blackjack

• Yellow light – Dealer has a potential blackjack hand, around 17+ points.
• Red light – Dealer definitively has blackjack, pays out 1.5x only.
• Green light – Round is a push/tie, player gets back their bet.

Craps

• Yellow lights – Indicates start of new phase – come out roll or point roll.
• Red lights – Highlight current point number needing to be rolled again.
• Green lights – Winning pass/don‘t pass bets are paid out.

Poker

• Yellow light – Last betting round begins, time to reveal hole cards.
• Flashing red – Winning hand activated by dealer.
• Blue light – Built into the felt to see chip stacks for video surveillance.

Now you can play almost any casino game like a pro just by deciphering the lights!

How Lighting Tricks Affect You as a Player

For recreational gamblers just looking to have a fun night out, lights add excitement and glamour to the casino environment. But for more serious players trying to maximize wins, understanding the light signals provides a definite tactical edge.

Noticing which machines have freshly lit candles or flashing bonus symbols can help identify favorable games with improved odds. Avoiding slots where the candle is flashing also means steering clear of technical issues that may reduce your chances of winning.

The psychological impact is also dramatic. Seeing slot machines light up with spinning reels and flashing jackpots creates a contagious feeling that you could hit it big any second too. Even if you don‘t win personally, the vicarious thrill from other players winning keeps the energy high.

Ultimately the lights encourage players to keep gambling longer, so be sure to set limits for yourself and take occasional breaks to make level-headed decisions.

Okay, now that you‘re a casino lighting expert, let‘s shift gears a bit…

A Brief History of Red Light Districts

Given the subject of red lights in casinos, I wanted to share some fascinating historical context about the term "red light district" and how it relates to gambling:

• Origin – The first red light area appeared in the 1880s in Dodge City, Kansas. Railroad workers frequented brothels lit by red lanterns near the tracks.

• Spread – Similar red light zones popped up in other cities like New Orleans and San Francisco. Amsterdam‘s De Wallen became the most famous.

• Gambling ties – Casinos were often constructed near red light districts. Prostitution also thrived in rowdy mining towns and military bases.

• Decline – Most red light areas disappeared by the mid-1900s due to anti-prostitution campaigns.

• Remaining – Today only a few licensed red light districts are still operating, like the Bunny Ranch in Nevada.

So the connotation between red lighting and risqué adult entertainment explains how red became linked with low denomination slot machines!

Alright, let‘s wrap this up…
