How Do Slots Work?

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
• Massive 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.

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 free spins, a minigame, or selecting a hidden prize.

Progressive Jackpot Slots

When a slot has a progressive jackpot, it means a portion of every bet placed by everyone playing the slot contributes to a running total. The total progressive jackpot continues to increase as people play until it’s won by a lucky player, then it’s reset 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.

Should You Always Do Max Bet?

No. You should always play with however much you’re able to lose.

However, playing max bet does two things. First, it gives you the best chance of winning the highest possible prizes. 

Further, 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.

Understanding Slot strategy

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.

Volatility

When a slot is labeled low volatility, it means it pays out low wins regularly. When it’s labeled high volatility, it means you’ll often go for several spins without winning, but the winning streaks are often larger when they do come.

Different Types Of Slot Machines

Because slots are always innovating, it’s difficult to create a list of the different types. Instead, let’s look at the key factors that separate one slot from another.

Number Of Reels

Three-reel slots are usually the simplest, where one payline runs across a maximum of three symbols. 

Five-reel slots are the most common and can range from a handful of paylines to 743 All-Ways-Pays slots, which covers every possible combination of symbols going up and down and left to right across the reels.

Four-reel, six-reel, seven-reel, and other slots are pretty much nonexistent in physical casinos but you can find some online relatively easily.

Video Vs. 3D Slots

Video slots are the most common form of five-reel slots and often feature bonus and free spin features. 3D slots are the same, except they use 3D animation and graphics whereas video slots use 2D.

Denominations

Penny slots earned their name by allowing players to bet with just $0.01. But some slots can cost a minimum of $1.00 per spin, and betting the max can make your overall wager climb to as high as $125 or more.

Coin Play Vs. Paylines

Coin play means you’re simply setting the coin value that applies to the multiplier wins. Some variations, called Buy-Your-Pay Slots, won’t allow you to win certain amounts or activate certain features unless you increase your coin value.

Paylines are either fixed or variable. For both, you set the value of each individual payline, and multiplier wins apply to that payline. But with variable paylines, you can set the number of lines you want to play as well as their value. With fixed paylines, you automatically play all of them.
