How Do Slots Work?

Overview

Whether free slots or paid slots, these make up, by far, the most popular casino game for a few key reasons:

• Huge winning potential
• Option to play for low or high stakes
• Extremely simple gameplay
• Many types of slots mean huge variety

Once you know the basics of slots, you’ll be able to play any type that you’ll come across. While each title can seem wildly different, they all work in fundamentally the same way (although some boast odds that make them the best payout slots).

The object of a slot machine is for a winning combination of symbols to appear when the reels stop. This is true whether it’s a three-reel or a five-reel slot.

Paylines

A winning combination of symbols is based on paylines that run across the reels. A slot can have as few as five paylines or over a hundred. 

Usually, the symbol combinations are left to right across the paylines, and each payline can win independently. That means the more paylines you play, the higher your chances of scoring a payout.

In slots, wins are multipliers, not set amounts. So if you’re playing a slot with 25 paylines and your total wager is $5.00, each payline would have a value of $0.20. If one scored a 100x multiplier, you’d win $20.

To play all paylines for the highest possible value, you can select “Max Bet.”

Wild Symbols

The Wild symbol usually best matches the theme of the game. For example, Cleopatra is the Wild symbol in the Cleopatra slot. 

Wild symbols can take the place of any other symbol aside from the scatter (and possibly other specialty symbols) to create winning combinations. Five wild symbols will often trigger the top prize fixed jackpot.

Bonus Features

A slot’s biggest selling point aside from the jackpot, RTP, and overall theme are the bonus features. These are usually triggered when three or more “scatter” symbols appear on the reels. You then have the opportunity to win more money, either through a spins bonus, minigame, or selecting a hidden prize.

Progressive Jackpots

Slots with progressive jackpots feature a grand prize that grows because every bet that’s placed contributes to the running total. That is, until it’s won by a lucky player, then it resets and starts again. 

How to win a progressive jackpot depends on the slot. In some cases, it’s simply randomly awarded at the end of a spin, and you may need to “Bet Max” to qualify. Others will involve a bonus game.

Max Bet

You should not play max bet every time. You should only play with however much you’re able to lose.

But playing max bet does do two things. First, it gives you the best chance of winning the highest possible prizes. Two, you may need to play max bet to qualify for certain prizes, including the progressive jackpot. Check the rules of the specific slot to make sure.

Types of Slots & Their Features

No other casino game offers a level of variety quite like slots. The game ranges immensely in terms of payout odds, volatility, themes, bonus features, bet minimums, maximum payouts, and more. Here’s a breakdown of the types of features you can look out for.

1. Return to Player (RTP)

A slot’s payback rate, or return to player (RTP), is how much a player can expect to keep of their bankroll based on the average net wins. A high slot payback is 96% or higher, although some slots pay back as low as 92% because they offer massive jackpots.

No slot has an average lifetime payback that’s equal to or greater than 100%. However, some players seek out the games with the highest RTP to ensure the highest chances of regular wins. Others prefer the longshot slots, which have the lowest RTP but normally the highest potential prizes.

2. Volatility

The volatility of a slot represents how often it pays and the types of wins it typically triggers. The higher a slot’s volatility, the less often it pays but the bigger the wins. The lower the volatility, the more often it pays and the lower the wins. While all slots can trigger both big and small wins, volatility is often a better indication of how the slot will feel than RTP.

3. Reel Array

A slot reel array is the configuration of the slot reels and their symbols. Most people are familiar with stepper slots (three-reel classics) and standard video slots (five reels), but the reel array possibilities are truly endless. We’ve seen grids that look more like keno than slots.

4. Min/Max Bet

Penny slots earned their name by allowing bets of just $0.01, but players can find nickel, dime, and quarter slots too, all the way up to slots that require a minimum of $100 or more a spin (known as high limit slots). Players should expect most of their spins to lose or trigger a payout lower than the total wager, so it’s crucial to find a game that allows for an appropriate bet level per spin given your budget. Then again, playing free slots eliminates this problem, because you’re not risking your own money.

5. Paylines & Coin Value

Before you press the spin button on a slot machine, you have to set the amount of your wager. This can vary a bit depending on the slot, but it’s not all that complicated. You’ll either set the coin value, payline value, or total wager. For the coin wager, the more coins you play, the higher the potential payout. For the paylines, the more you play, the more chances you have to win per spin. And if it’s just setting a total wager, you’re likely playing a “fixed lines” or “all ways pays” slot, where the number of lines are pre-determined. The game will let you know the total value of the each spin before you hit go.

6. Theme

Many slots players choose a new game because they like the look of it at first glance. All slots play is based on random luck for the most part, so that’s as good a way as any to choose a new game to try. Slots themes are a lot like movie genres in that the characters, setting, and animations are based on the theme, but the structure is more or less the same. Looking for more free slots?
