Chances Of Winning A Slot Machine Jackpot

Basically, when it comes to slot machines, strategy boils down to this: Know the rules, your probability of winning, and the expected payouts; dispel any myths; and quit while you’re ahead. If you win $100, cash out $50 and play with the rest, for example. After you lose a certain amount (determined by you in advance), don’t hesitate to quit.

Introduction

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.

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.

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.

Here are some great ways to increase your chances at winning at the slot machines in a casino, or just about anywhere that you encounter a slot machine! Luck plays a huge role in successfully winning at slot machines, but there are some slot machine strategies that can maximize your chances to win. The probability of winning a significant amount of money on slot machines is slim to none. Casinos do not ordinarily disclose the odds of winning at their slot machines, so the slot players cannot be informed of their chances of winning. Believe me… the chances of winning big money on the slots are very low. However, most people do love to play the slots, and you can still increase your chances of winning some money with a few tips as follows.

Winning Slot Jackpots Videos

Some video slot machines have a fixed maximum payout while other machines have progressive jackpots, which means they have a meter which increases the jackpot with every play where there is no return. The more people play these slot machines… the higher the jackpot becomes.

Progressive slots might seem to be the most attractive, due to the supposed high return, however the huge disadvantage of the progressive slots is that in most online casinos they are all linked together. Because of the number of people all playing for that huge jackpot amount, your odds of winning on a progressive slot machine are much lower. That lower probability of winning not only applies to the jackpot amounts, but also for the overall odds of winning smaller amounts. So it is more profitable to stick to the machines with a fixed maximum payout and limit your play on the progressive ones with the huge jackpots.

Jackpot

To have the very best chances of winning, at least in the short term, you should choose the slots that offer the smallest jackpots. These smaller jackpots are easier to win, which will increase your chances of walking away a winner. The bigger the jackpot, the harder it is to actually hit, and it is more likely that you might lose. It takes a lot of playing hours to create the huge jackpots which is why your chances of winning them are much lower. Games that are novelty themed with enormous jackpots have the worst odds of all, so you really should stick to the machines with the smaller prizes.

This is an amazing book, which everyone should have, if they play slot machines regularly!

You won’t find it in a library or bookstore, but you can click on the photo and find a site where they sell it at a bargain price! Some online retailers charged $29.95 or $19.95 for the very same booklet!
