Slot machines are the most exciting casino games in the world. The combination of simplicity and huge jackpots - along with plenty of psychological factors designed in the game (best explained in Addiction by Design: Machine Gambling in Las Vegas by Natasha Dow Schull) ensure that Americans keep pouring billions of dollars a year into slots. The downside for customers? You'll lose by a wide margin in the long run, and in general the bigger the jackpot, the more of an edge the slot machine has over you.

You can increase your chances in the long run, though, by choosing the right games at the right casinos -- it's not unheard of that you will lose five times the amount on average that you would have lost if you chose the best slot machines and played at the best online casinos.

How Real-Money Slots Work - The Basics

A slot machine has no feelings. The amount of winnings it pays are dictated by the EPROM chip and the random number generator ('RNG') inside the machine. It doesn't consider whether someone has recently won or lost -- every spin of the reels is random.

It's possible to influence your chances of winning at slots. When you press Spin, the RNG generates a random number (between one and a billion, for example) for each reel of the machine. Every number represents one of the symbols (the more numbers represent a symbol, the more it is 'weighted' in the machine).

The EPROM chip then determines whether you've won with the combination of symbols or not; the more winning combinations there are, and the more the player wins per winning combination, the higher the odds of winning and the payback of the machine.

Suggesting you have all the information available, calculating your chances of winning at slots is simple: multiply the probability of each outcome with what those outcomes pay, and then sum the results. It's always under 100% (otherwise casinos would make no profit) and often near 90% (casinos make a lot of money from slots).

Here's an example of an imaginary slot machine (let's call it King of Cats) with three winning combinations -- a real-life slot machine works the same way, but likely with more ways of winning at slots:

Combination	Pays	Probability	Return
Three Lions	2500	0.001%	0.025
Three Tigers	1000	0.015%	0.15
Three Jaguars	400	0.05%	0.2
Three Leopards	50	0.5%	0.25
Three Cheetahs	5	7%	0.35
Total	3955	7.566%	0.975

The slot machine above would return 97.5% to players in the long run. However, we rarely know the odds of slot machines. We do know the paytable - how much each winning combination pays to players - but we have no idea of the probability of getting that winning combination.

To calculate the probability of a winning combination, we need to know is how many stops there are for each symbol. For example, in the machine above there could be 45 stops and one of them would be a Lion symbol. By calculating (1/45)*(1/45)*(1/45) we get 0.001%, or the probability of hitting three Lion symbols in a row.

In real world, those symbols would have been weighed differently so that they're more likely to come on the first two reels and much less likely to come on the last reel, resulting in a near-miss situation.

I advise you not to play at all because slot machine odds are never good, but if you're going to play anyway, here's how you can find the slot machines that likely have better odds than others.

Why We Lose At Slots

We lose at slot machines because they're set to give back less than they take on average. It's impossible to play slot machines better; you can just press spin and hope for the best. With that said, though, you can improve your odds of winning at slot machines greatly by making good decisions before playing and having a good strategy when entering a casino - more about that lower on this page.

Generally, the more decisions you can make in a casino game, the lower the house edge is (with optimal play). Since there's almost no room for decisions when playing slots machines - again, your only decision is to press spin - the house edge is high at slots when compared to other popular casino games. And since you play slot machines for real money so fast (400-800 spins an hour), you lose more at slots than at any other casino game. (Read how slots work to understand them better.)

Like most casino games, a slot machine is a game of independent trials (the previous game has no influence on the next game). Your chances of winning with each spin are the same regardless of whether you've lost or won. So, there's absolutely no room for in-play slot machine strategy.

How Much Do Slot Machines Pay Back?

A slot machine's payback percentage could be anywhere from 75% to almost 100%, but of course, always lower than 100% (otherwise, the casino would make no profit). You can calculate a casino game's house edge by subtracting its payback percentage from 100% - this is how much the casino makes per bet in the long run. For example, with a 5% house edge, casinos make $5 per every $100 bet.

Calculating a slot machine's payback percentage is easy if you have all the information available: multiply the probability of each outcome with what they pay, and the sum is how much the slot machine returns in the long run, also known as its 'payback.'

But most of the time we don't have that information. We're in the dark -- sure, casinos can claim certain payback or payout percentages but how do we know they're truthful? Some online casinos get their payouts reviewed by private auditors, but how do we know if the auditors are honest?

It's a different situation with games like blackjack or roulette; in both cases we can calculate the house edge because the rules are known. If you care enough to make the calculations (and you should), you'll know exactly how much you stand to lose or win in the long run.

You could argue that casinos make so much money from slot machines that they have no reason to cheat. I agree, but you can still get a raw deal even if they are honest (setting a low payback percentage is not cheating). I want to have an idea of what kind of a return I get for my money regardless of the honesty of the casino. (See how to pick slot machines to find the best slots to play.)
