Introduction
They look like slot machines, spin like slot machines, beep and whir and shell out big winnings like slot machines. And yet slot machines, even back in 2015, were illegal according to the Idaho. One such device, similar in appearance to a slot-machine, is a patented product marketed under the name “Instant Racing.”2 The bettor inserts money or its equivalent into the Instant Racing terminal and then chooses a horse identified by a number.
When it comes to gambling, the easier a game is to understand the worse the odds usually are. This is certainly the case with slot machines. Playing them is as easy as pressing a button. However, between the high house edge and fast rate of play, there is no quicker way to lose your money in a casino.
Before going further, let me make clear that this page addresses the way slot machines work in most parts of the United States and the world. However, some parts of this page do not apply everywhere. For example, I state that slot machines have a memory-less property, where the odds of every spin are the same. In some places, like the UK, some machines in bars, called 'fruit machines,' have a mechanism that guarantees a certain profit over the short run, which causes the game to go through loose and tight cycles. These games do not have the usual independence property of the major slot makers.
How They Work
Whether you're playing a 3-reel single-line game or a 5-reel 25-line game, the outcome of every bet is ultimately determined by random numbers. The game will choose one random number for each reel, map that number onto a position on the reel, stop the reel in the appointed place, and score whatever the outcome is. In other words, the outcome is predestined the moment you press the button; the rest is just for show. There are no hot and cold cycles; your odds are the same for every spin on a given machine.
Slot machines are just about the only game in the casino where the odds are not quantifiable. In other words, the player doesn't know how the game was designed, so it is difficult to look at an actual game to use as an example. So, to help explain how they work, I created the Atkins Diet slot machine (link). It is a simple, five-reel game with a free spin bonus round, much like IGT's Cleopatra game.
For information on how it works and all the odds, please visit my Atkins Diet par sheet.
For a more complicated example, featuring sticky wilds in the bonus, please try my Vamos a Las Vegas slot machine.

Odds
The following table shows the casino win for Clark County Nevada (where Las Vegas is) for all slots for calendar year 2012. They define 'slot' as any electronic game, including video poker and video keno. I've found video keno to be about equally as tight as reeled slots, but video poker has a much higher return. So, the return for reeled slots should be higher than these figures.
Clark County Slot Win 2012
Denomination | Casino Win (pct) |
---|---|
$0.01 | 10.77% |
$0.05 | 5.96% |
$0.25 | 5.74% |
$1.00 | 5.64% |
$5.00 | 5.51% |
$25.00 | 3.97% |
$100.00 | 4.73% |
Megabucks | 12.89% |
Multi-denomination | 5.32% |
Total | 6.58% |

Most players play penny video slots. Based on past research, I find the house edge on those to usually be set from 6% to 15%. In general, the nicer the casino, the tighter the slots.
Advice
While there is no skill to playing slots, there is some skill in selecting which machine to play and ways you can maximize your return. What follows is my advice, if you must play slots at all.
- Always use a player card. Slots may be a lousy bet, but the casinos treat slot players very well. A $1 slot player will probably get comped better than a $100 blackjack player. Of course, don't play for the reason of getting comps. You'll give them a lot more than they'll give you.
- The simpler the game, the better the odds. The fancy games with big signs and video screens tend to not pay as well as the simple games. However, slot players always tell me the fancy games are more fun.
- The higher the denomination, the better the odds. For that reason, it is better to play one coin per line on a 5-cent game than five coins per line on a 1-cent game.
- Don't forget to cash out and take your ticket when you leave. It is easy to forget after hitting a jackpot.
- Try to play slowly and as little as possible to get your fix.
- In some games there is a skill feature, like Top Dollar. In such games, advice is usually offered, which you should take.
Myths and Facts
Just about everything that players believe about slots is untrue. Here are the most common myths and facts. As a reminder, this page is based on slot machines commonly found in the United States. Some machines, like 'fruit machines' found in the United Kingdom work differently.
- Myth: Slot machines are programmed to go through a cycle of payoffs. Although the cycle can span thousands of spins, once it reaches the end the outcomes will repeat themselves in exactly the same order as the last cycle.
Fact: This is not true at all. Every spin is random and independent of all past spins.
- Myth: Slot machines are programmed to pay off a particular percentage of money bet. Thus, after a jackpot is hit the machine will tighten up to get back in balance. On the other hand, when a jackpot has not been hit for a long time it is overdue and more likely to hit.
Fact: As just mentioned, each spin is independent of all past spins. That means that for a given machine game, the odds are always the same. It makes no difference when the last jackpot was hit or how much the game paid out in the last hour, day, week, or any period of time.
- Myth: Machines pay more if a player card is not used.
Fact: The mechanism that determines the outcome of each play does not consider whether a card is used or not. The odds are the same with or without one.
- Myth: Using a player card enables the casino to report my winnings to the IRS.
Fact: That makes no difference. If you win $1,200 or more they will report it either way. If you have a net losing year, which you probably will, at least the casino will have evidence of it. Such annual win/loss statements may be used as evidence to declare offsetting loses to jackpot wins.
- Myth: The slot department can tighten my game with the press of a button remotely. Thus, you better be nice to the staff and tip them well, or they will use a remote control to have the machine take you down in a hurry.
Fact: There is now some truth to the myth that the odds of a machine can be changed remotely. Such 'server-based slots' are still experimental and in a minority. Even with server-based slots, there are regulations in place to protect the player from the perceived abuses that could accompany them. For example, in Nevada a machine can not be altered remotely unless it has been idle for at least four minutes. Even then, the game will display a notice that it is being serviced during such changes. (source) Meanwhile, for the vast majority of slots, somebody would physically need to open the machine and change a computer chip, known as an EPROM chip, to make any changes.
- Myth: The machines by the doors and heavy traffic flow areas tend to be loose while those hidden in quiet corners tend to be tight.
Fact: I've studied the relationship between slot placement and return and found no correlation. Every slot director I've asked about this laughs it off as just another player myth.
- Myth: Slots tend to be looser during slow hours on slow days of the week. However, when the casino is busy they tighten them up.
Fact: Nobody would take the trouble to do this, even if he could. The fact of the matter is the casinos are trying to find a good balance between winning some money while letting the player leave happy. That is best achieved by slots loose enough to give the player a sufficiently long 'time on device,' as they call it in the industry, with a reasonable chance of winning so he will return to the same casino next time. If the slots are too tight, the players will sense it and be unlikely to return.
The kind of place you're likely to find tight slots are those with a captive audience, like the Las Vegas airport. So, if the slot manager feels that 92% is the right return for a penny game, for example, he is likely to set every penny game all that way, and keep them that way for years.

Introduction to Kentucky Slot Machine Casino Gambling in 2020
Kentucky slot machine casino gambling does not include games of chance, which are strictly illegal. Instead, Kentucky has competition-based electronic gaming machines at four out of its five pari-mutuel wagering racetracks.
Theoretical payout limits are not available but monthly return statistics are available for electronic gaming machines.
This post continues my weekly State-By-State Slot Machine Casino Gambling Series, an online resource dedicated to guiding slot machine casino gambler to success. Now in its third year, each weekly post reviews slots gambling in a single U.S. state, territory, or federal district.

Relevant Legal Statutes on Gambling in Kentucky*
The minimum legal gambling age in Kentucky depends upon the gambling activity:
- Land-Based Casinos: Not available
- Poker Rooms: Not available
- Bingo: 18
- Lottery: 18
- Pari-Mutuel Wagering: 18
Kentucky’s interpretation of legal gambling requires the competitor’s level of skill “must sufficiently govern the results.”
Therefore, competition-based games are legal as well as pari-mutuel wagering. Traditional slots are illegal, including those referred to as Class III, Vegas-style, and games-of-chance slot machines.
Kentucky has competition-based electronic games available in a few of their pari-mutuel facilities. These skill-based games are anonymously-based historical race results.
Historically, Kentucky has had a fascinating relationship with gambling. While casino gambling was never legal, gambling dens were prevalent before the Great Depression of 1929. To this day, the open display of illegal gambling from that time in American history continues to negatively affect the perception of gaming in Kentucky.
If you’re ever in Newport, directly across the Ohio River from Cincinnati, consider walking the Newport Gangster Tour.
*The purpose of this section is to inform the public of state gambling laws and how the laws might apply to various forms of gaming. It is not legal advice.

The Kentucky Horse Racing Commission offers statistics for HHR gaming under Quick Links entitled Wagering on Historical Horse Races. Its December 2019 report indirectly offers actual return statistics including comparisons to past actuals.
To calculate a player’s win percentage from the report, divide Less: Return to Public by Total Handle. For December 2019, the monthly Player’s Win% for HHR machines were:
- State-wide: 91.5%
- Derby City: 90.9%
- Ellis Park: 93.9%
- Keeneland/Red Mile: 91.3%
- Kentucky Downs: 92.0%
From this December 2019 report, Ellis Park had the highest player win% at nearly 94% while Derby City had the lowest at nearly 91%.
Summary of Kentucky Slot Machine Casino Gambling in 2020
Kentucky slot machine casino gambling exists as competition-based, games-of-skill Historical Horse Racing (HHR) electronic gaming machines instead of games-of-chance slot machines.
No minimum or maximum theoretical payout limits have been set. Monthly return statistics are publicly available for each pari-mutuel racetrack with HHR games.
