In the not-too-distant past, slot-machine players were the second-class citizens of casino customers. Jackpots were small, payout percentages were horrendous, and slot players just weren't eligible for the kind of complimentary bonuses -- free rooms, shows, meals -- commonly given to table players. But in the last few decades the face of the casino industry has changed. Nowadays more than 70 percent of casino revenues comes from slot machines, and in many jurisdictions, that figure tops 80 percent.

About 80 percent of first-time visitors to casinos head for the slots. It's easy -- just drop coins into the slot and push the button or pull the handle. Newcomers can find the personal interaction with dealers or other players at the tables intimidating -- slot players avoid that. And besides, the biggest, most lifestyle-changing jackpots in the casino are offered on the slots.

The following article will tell you everything you need to know about slots, from the basics to various strategies. We'll start at square one, with a primer on how playing slot machines works.

There are at least two different accounts of the original invention of slot machines. One is that the first device was the Liberty Bell machine, invented by an American named Charles Fey in 1887.

How to Play

Where Are Slot Machines Made

The most popular slots are penny and nickel video games along with quarter and dollar reel-spinning games, though there are video games in 2-cent, 10-cent, quarter, and dollar denominations and reel spinners up to $100. Most reel spinners take up to two or three coins at a time while video slots can take 45, 90, and even 500 credits at a time.

Nearly all slot machines are fitted with currency acceptors -- slide a bill into the slot, and the equivalent amount of credits is displayed on a meter. On reel-spinning slots, push a button marked 'play one credit' until you've reached the number of coins you wish to play. Then hit the 'spin reels' button, or pull the handle on those few slots that still have handles, or hit a button marked 'play max credits,' which will play the maximum coins allowed on that machine.

On video slots, push one button for the number of paylines you want to activate, and a second button for the number of credits wagered per line. One common configuration has nine paylines on which you can bet 1 to 5 credits. Video slots are also available with 5, 15, 20, 25, even 50 paylines, accepting up to 25 coins per line.

Many reel-spinning machines have a single payout line painted across the center of the glass in front of the reels. Others have three payout lines, even five payout lines, each corresponding to a coin played. The symbols that stop on a payout line determine whether a player wins. A common set of symbols might be cherries, bars, double bars (two bars stacked atop one another), triple bars, and sevens.

A single cherry on the payout line, for example, might pay back two coins; the player might get 10 coins for three of any bars (a mixture of bars, double bars, and triple bars), 30 for three single bars, 60 for three double bars, 120 for three triple bars, and the jackpot for three sevens. However, many of the stops on each reel will be blanks, and a combination that includes blanks pays nothing. Likewise, a seven is not any bar, so a combination such as bar-seven-double bar pays nothing.

Video slots typically have representations of five reels spinning on a video screen. Paylines not only run straight across the reels but also run in V's, upside down V's, and zigs and zags across the screen. Nearly all have at least five paylines, and most have more -- up to 50 lines by the mid-2000s.

In addition, video slots usually feature bonus rounds and 'scatter pays.' Designated symbols trigger a scatter pay if two, three, or more of them appear on the screen, even if they're not on the same payline.

Similarly, special symbols will trigger a bonus event. The bonus may take the form of a number of free spins, or the player may be presented with a 'second screen' bonus. An example of a second screen bonus comes in the long-popular WMS Gaming Slot 'Jackpot Party.' If three Party noisemakers appear on the video reels, the reels are replaced on the screen with a grid of packages in gift wrapping. The player touches the screen to open a package and collects a bonus payout. He or she may keep touching packages for more bonuses until one package finally reveals a 'pooper,' which ends the round. The popularity of such bonus rounds is why video slots have become the fastest growing casino game of the last decade.

When you hit a winning combination, winnings will be added to the credit meter. If you wish to collect the coins showing on the meter, hit the button marked 'Cash Out,' and on most machines, a bar-coded ticket will be printed out that can be redeemed for cash. In a few older machines, coins still drop into a tray.

Etiquette

Many slot players pump money into two or more adjacent machines at a time, but if the casino is crowded and others are having difficulty finding places to play, limit yourself to one machine. As a practical matter, even in a light crowd, it's wise not to play more machines than you can watch over easily. Play too many and you could find yourself in the situation faced by the woman who was working up and down a row of six slots. She was dropping coins into machine number six while number one, on the aisle, was paying a jackpot. There was nothing she could do as a passerby scooped a handful of coins out of the first tray.

Sometimes players taking a break for the rest room will tip a chair against the machine, leave a coat on the chair, or leave some other sign that they'll be back. Take heed of these signs. A nasty confrontation could follow if you play a machine that has already been thus staked out.

Payouts

Payout percentages have risen since the casinos figured out it's more profitable to hold 5 percent of a dollar than 8 percent of a quarter or 10 percent of a nickel. In most of the country, slot players can figure on about a 93 percent payout percentage, though payouts in Nevada run higher. Las Vegas casinos usually offer the highest average payouts of all -- better than 95 percent. Keep in mind that these are long-term averages that will hold up over a sample of 100,000 to 300,000 pulls.

In the short term, anything can happen. It's not unusual to go 20 or 50 or more pulls without a single payout on a reel-spinning slot, though payouts are more frequent on video slots. Nor is it unusual for a machine to pay back 150 percent or more for several dozen pulls. But in the long run, the programmed percentages will hold up.

The change in slots has come in the computer age, with the development of the microprocessor. Earlier slot machines were mechanical, and if you knew the number of stops -- symbols or blank spaces that could stop on the payout line--on each reel, you could calculate the odds on hitting the top jackpot. If a machine had three reels, each with ten stops, and one symbol on each reel was for the jackpot, then three jackpot symbols would line up, on the average, once every 10310310 pulls, or 1,000 pulls.

On those machines, the big payoffs were $50 or $100--nothing like the big numbers slot players expect today. On systems that electronically link machines in several casinos, progressive jackpots reach millions of dollars.

The microprocessors driving today's machines are programmed with random-number generators that govern winning combinations. It no longer matters how many stops are on each reel. If we fitted that old three-reel, ten-stop machine with a microprocessor, we could put ten jackpot symbols on the first reel, ten on the second, and nine on the third, and still program the random-number generator so that three jackpot symbols lined up only once every 1,000 times, or 10,000 times. And on video slots, reel strips can be programmed to be as long as needed to make the odds of the game hit at a desired percentage. They are not constrained by a physical reel.

Each possible combination is assigned a number, or numbers. When the random-number generator receives a signal -- anything from a coin being dropped in to the handle being pulled -- it sets a number, and the reels stop on the corresponding combination.

Between signals, the random-number generator operates continuously, running through dozens of numbers per second. This has two practical effects for slot players. First, if you leave a machine, then see someone else hit a jackpot shortly thereafter, don't fret. To hit the same jackpot, you would have needed the same split-second timing as the winner. The odds are overwhelming that if you had stayed at the machine, you would not have hit the same combination.

The First Slot Machine

Second, because the combinations are random, or as close to random as is possible to set the program, the odds of hitting any particular combination are the same on every pull. If a machine is programmed to pay out its top jackpot, on the average, once every 10,000 pulls, your chances of hitting it are one in 10,000 on any given pull. If you've been standing there for days and have played 10,000 times, the odds on the next pull will still be one in 10,000. Those odds are long-term averages. In the short term, the machine could go 100,000 pulls without letting loose of the big one, or it could pay it out twice in a row.

So, is there a way to ensure that you hit it big on a slot machine? Not really, but despite the overriding elements of chance, there are some strategies you can employ. We'll cover these in the next section.

Slots are the easiest games in the casino to play -- spin the reels and take your chances. Players have no control over what combinations will show up or when a jackpot will hit. There is no way to tell when a machine will be hot or cold. Still, there are some pitfalls. It's important to read the glass and learn what type of machine it is. The three major types of reel-spinning slots are the multiplier, the buy-a-pay, and the progressive.

The multiplier. On a multiplier, payoffs are proportionate for each coin played--except, usually, for the top jackpot. If the machine accepts up to three coins at a time, and if you play one coin, three bars pay back ten. Three bars will pay back 20 for two coins and 30 for three coins. However, three sevens might pay 500 for one coin and 1,000 for two, but jump to 10,000 when all three coins are played. Read the glass to find out if that's the case before playing less than the maximum coins on this type of machine.

The buy-a-pay. Never play less than the maximum on a buy-a-pay, on which each coin 'buys' a set of symbols or a payout line. The first coin in might allow the player to win only on cherry combination, while the second coin activates the bar payouts, and the third coin activates the sevens. Woe is the player who hits three jackpot symbols on a buy-a-pay with only one coin played--the player gets nothing back. A variation is the machine with multiple payout lines, each activated by a separate coin. All symbols are active with each coin, but if a winning combination lines up on the third-coin payout line with only one or two coins played, the payoff is zero.

The progressive. You also have no reason to play less than maximum coins on a progressive machine. A player who eventually lines up the jackpot symbols gets a percentage of each coin played. The first progressive machines were self-contained--the jackpot was determined by how much that particular machine had been played since the last big hit. Today most progressives are linked electronically to other machines, with all coins played in the linked machines adding to a common jackpot.

These jackpots can be enormous -- the record is $39,710,826.26, a $1 progressive at a Las Vegas casino. The tradeoff is that frequency and size of other payouts are usually smaller. And you can't win the big jackpot without playing maximum coins.

If you must play fewer than maximum coins, look for a multiplier in which the final-coin jump in the top jackpot is fairly small. Better yet, choose a machine that allows you to stay within your budget while playing maximum coins. If your budget won't allow you to play maximum coins on a $1 machine, move to a quarter machine. If you're not comfortable playing three quarters at a time, move to a two-quarter machine. If you can't play two quarters at a time, play a nickel machine.

With so many paylines and the possibility of betting multiple coins per line, video slots are different. Some penny slots with 20 paylines take up to 25 coins per line. That's a $5 maximum bet -- a pretty penny indeed! Most players bet less than the max on video slots but are sure to cover all the paylines, even if betting only one coin per line. You want to be sure to be eligible for the bonus rounds that give video slots most of their fun. Some progressive jackpots require max coins bets, and some don't. If a max-coins bet is required to be eligible for the jackpot and you're not prepared to roll that high, find a different machine.

Money Management

Managing your money wisely is the most important part of playing any casino game, and also the most difficult part of playing the slots. Even on quarter machines, the amount of money involved runs up quickly. A dedicated slot player on a machine that plays off credits can easily get in 600 pulls an hour. At two quarters at a time, that means wagering $300 per hour -- the same amount a $5 blackjack player risks at an average table speed of 60 hands per hour.

Most of that money is recycled from smaller payouts--at a casino returning 93 percent on quarter slots, the expected average loss for $300 in play is $21. Still, you will come out ahead more often if you pocket some of those smaller payouts and don't continually put everything you get back into the machine.

One method for managing money is to divide your slot bankroll for the day into smaller-session bankrolls. If, for example, you've taken $100 on a two-and-a-half-hour riverboat cruise, allot $20 for each half-hour. Select a quarter machine -- dollar machines could devastate a $100 bankroll in minutes -- and play the $20 through once. If you've received more than $20 in payouts, pocket the excess and play with the original $20. At the end of one half-hour, pocket whatever is left and start a new session with the next $20.

If at any point the original $20 for that session is depleted, that session is over. Finish that half-hour with a walk, or a snack, or a drink until it is time for a new session. Do not dip back into money you've already pocketed.

That may seem rigid, but players who do not use a money management technique all too frequently keep pumping money into the machine until they've lost their entire bankroll. The percentages guarantee that the casino will be the winner in the long run, but lock up a portion of the money as you go along, and you'll walk out of the casino with cash on hand more frequently.

That is changing in new server-based slots that have started to appear in casinos. Operators will be able to change payback percentages at the click of a mouse, but they still must have regulatory approval to do so.

There is a lot more to slot machines than meets the eye. But if you learn the ins and outs of playing them, you can use some strategies that just might help you hit the jackpot.

Introduction

The first mechanical slot machine was invented in the late 1800's by a Bavarian imiagrant named Charles Fey (1862-1944) in San Francisco. In order to understand the history of the slot machine though we need to jump back a little in time.

Poker Machines

Before Fey’s invention there were other coin-operated games of chance. The most popular one, invented by Sittman and Pitt of New York, was a 'poker machine' that was similar to a slot machine and used 5 reels with 10 poker cards on each reel. These machines were very profitable and were used in hundreds of locations (mainly in cigar stands) in the 90's (the 1890's that is). The machines paid out prizes, like a free cigar or free drinks, which were distributed manually by an attendant.

Charles Fey

When Charles began building machines, he initially built ones that were similar the popular poker machines and called them by various names, like the 'Duke' and the 'Klondike'. After building a few of them, placing them in locations, and doing very well with them, he then opened a factory in San Francisco to work on his machines full-time.

But Fey wanted to build a machine that would pay out automatically. This wasn't possible at the time due to the difficulty of calculating the vast number of winning combinations of a machine with 5 reels and 10 cards on each reel. So, in 1898, Fey designed a poker machine called the 'Card Bell' machine that retained the card symbols of the earlier poker machines but had only 3 spinning reels and only 5 symbols printed on each reel. The automatic prize-payout allowed the machine to be the first to pay out coins.

The 'Liberty Bell'

About a year later, in 1899, he created the 'Liberty Bell' machine, which added horseshoes and bells to the suit symbols on the reels. Lining up three bells would win the top prize (hence the name). Fey's design became the standard design for slot machines going forward and was so popular that all 3-reel slot machines were referred to as 'Bell Machines'.

Fey rented his machines to saloons and bars and split the profits 50/50. The demand for Liberty Bell slot machines was huge and allowed Fey to monopolize the slot machine market. Many gambling supply manufacturers wanted to buy the manufacturing and distribution rights to the Liberty Bell but Charles Fey didn't want to sell them.

But Fey could not keep up with the demand so in 1907 he partnered with Mills Novelty Company to manufacture a cast-iron machine called the 'Mills Liberty Bell'.

Unfortunately for Fey, patent laws of the time did not protect gaming devices because a Federal Judge ruled the slots could only be used for gambling and had no useful purpose. So a few years later, in 1910, the Mills Novelty Company introduced a slight variation to the Mills Liberty Bell called the 'Operator Bell'. The machines from Mills Novelty were the first to use the fruit symbols like lemons and cherries that you see on some slot machines today.

1910-1933

Part of the growth of slot machines was due the wide open nature of San Francisco during the early 1900's. The climate started to change quickly though in 1909 when San Francisco outlawed all gaming machines. Nevada did the same a year later and the state of California created a statewide ban on slot machines in 1911.

The First Ever Slot Machine

These laws did not have much of an effect on slot machine sales because slot machine manufacturers were able to find ways to alter the games to avoid getting them classified as gambling devices.

For example, the 'Liberty Bell Gum Fruit' model dispensed a package of gum, which allowed the machine to be classified as a vending machine. The Caille Brothers slots created machines that had a Swiss music box located in the bottom of the cabinet so the machine was classified as a musical device. Another popular strategy was to have slot machines dispense items like mints or gum in order to have them classified as vending machines.

1800s Slot Machine

Slot machines reached their peak sales during the Great Depression and the lawless days of prohibition, which began in 1919. They were popular in the speakeasies as well as the many respectable businesses that needed the profitable machines in order to stay in business during the tough economic times.

1933-1945

After prohibition ended the government decided to target slot machines since they were looked at as tools for organized crime. Raids began to increase as well as laws prohibiting the possession of slot machines or a sale of a slot machine to an illegal state. Despite these efforts, the popularity of slots machines was difficult to stop and slots were still able to operate in some places.

Post WWII

First Ever Slot Machine

After World War II, governments started to become friendly to the slot machine industry because it now looked at it as a source of tax revenue.

The First Ever Slot Machine Machines

Computer Technology

In 1963, Bally developed the first electromechanical slot machine, called Money Honey, that used electronic micro-processors to decide the outcome of the game.

The first fully-electronic slot machines were introduced in Las Vegas in 1975. They were built by the Fortune Coin Company and used simulated reels on a monitor. The electronic machines caught on slower than expected because many players did not trust the fairness of the machines. In 1978, the company that would later be known as International Game Technology bought out the Fortune Coin Company.

In 1984, a Norwegian scientist named Inge Telnaes received a patent for a device titled, 'Electronic Gaming Device Utilizing a Random Number Generator for Selecting the Reel Stop Positions.' International Gaming Technology (IGT) bought the patent in 1988 and now all slot manufacturers his technology must license the patent from IGT.
