Each game type provides different theming, special features, and jackpot prizes. Learning the difference between game types allows every player to make the best game decision when selecting a real money online slot game to play.

Let me show you the various types of games below and how to select a title to begin enjoying online slot gaming instead of feeling overwhelmed.

Read on to get started! 

Common Types of Slot Games 

Have you ever found yourself logged in to a new online casino and had no idea where to begin when it comes to slots? The options are vast, and you may have no idea where to begin if you do not know the difference between game types.

Below are examples of common slot game types you will find at every online casino. 

Let’s dive into each game type and find the best options for your specific online slot gaming needs. 


In this category, players have access to traditional-style slot games.

There are only three reels on the game grid and usually only one payline. Games will generally have a fruit theme.


This type of online slot game offers a more modern feel.

Games will have a grid consisting of a 5×3 or 5×4 set with plenty of extras. This category often provides:

  • Free spins
  • Wilds
  • Bonus rounds
  • Multipliers


With a progressive online slot game, players can access slots with a fixed or growing jackpot. Some games may offer one to four fixed jackpot prizes, while others will have progressive jackpots that grow as players spin the reels.

Either way, the jackpot prizes can quickly reach a five, six, or even seven-figure range!

Themed Games

With a themed game, the slot will be centered around a certain storyline, such as a popular movie or television show.

Games can also be based on pop culture or specific cultures such as Egyptian or Asian.


With a jackpot game, big prizes are waiting to be won. The jackpot options will be listed on the game info or even on the game grid.

Many times, such slots will offer mystery jackpot prizes that can pop up at any time!

How to Select an Online Slot Game

Selecting a game to play is fairly simple if you know which game type suits your playing style. If you are new to casino gaming, then 3-reel slots are best because they offer minimal features. More experienced players will enjoy the 5-reels or progressives, while casual gamers are better suited for themed games. 

Aside from the game type, there are other factors that players should consider when selecting an online slot game.

Keep the following tips in mind when selecting a game to play. 

Return to Player Percentage (RTP)

The Return to Player percentage is the percentage the software developer expects the game to provide a return on player investment.

The higher the RTP, the more chances you have to secure a win.

Do I have your attention? Look for slot games with 96% or higher RTP to boost winning potential.

Special Features

Games with special features are another great way to increase the chance of scoring a jackpot prize. Wilds and multipliers can increase wins, and free spins give you a way to play for free, saving your bankroll for more spins.

Read the info section of an online slot game to see what features a title provides before spinning the reels for real money.

Bonus Options

You will also find any bonus game details in the info section. Seek out games with bonuses to get more with your gameplay.

Slots that offer bonus games can provide additional jackpot potential or other incentives.

Bonus games are also a fun element that can take place on a secondary screen for more visual interest while you play.

So whether you fancy a little flutter for fun or you play to win big, there’s something for everyone when it comes to online slots games.
