Today we’ll look at some of the most popular types of online slot games to give you the information to decide which you should play and answer the question, which is the most popular type of online casino slot game in 2023.

Traditional Slots

Traditional slot games are the most straightforward and common type of game, available at most major UK online slot providers, as points out. They don’t offer many features, typically only having a few paylines and you won’t find as many bonus gameplay mechanics. These slot games usually only have three reels and one payline, making them easy to understand and get into. The most distinct feature of traditional slot games are the simple and recognizable symbols they use.

People mainly play traditional slot games because of this simplicity and the nostalgia they provide. It’s reminiscent of the earliest slot games, and for many people who had a great time back in the day, this type of slot game is like slipping on a glove: it’s comfortable, known, and gets the job done.

Some of the most popular traditional slot games include:

  • Lightning Joker
  • Reel King
  • Roaring Forties
  • Sunny Fruits
  • Sevens and Fruits Hold and Win
  • Pay Day

Multi-Line Slots

Multi-line slot games offer the most excitement due to their interesting and exhilarating mechanics. As the name suggests, this slot game provides multiple paylines to bet on within a single spin. This means you can earn money if you get combinations across all pay lines.


Moreover, you can bet different amounts per payline, providing flexible betting options. This online slot game has become very popular over recent years because you can increase your winning potential by spreading your bets across paylines.

Some of the most popular multi-line slot games include:

  • Jungle Jim El Derado
  • Viking Runecraft
  • Gonzo’s Quest
  • Lil’ Devil
  • Vikings Go to Hell

Video Slots

Most people assume that all online slot games are video slots, but this is a misinterpretation. Video slot games intensely focus on providing immersive themes, amazing graphics, and a wide variety of bonus features. In other words, using realistic or engaging graphics and advanced animations, video slots focus more on the video side of things. However, video slot games also focus on storylines which help to immerse players and give them a point of playing other than making money.

Much like multi-line slots, video slots also offer multiple paylines with a wide variety of betting options, allowing players to choose the number of paylines they’d like to use as well as the size of the bet per payline. You might love this type of slot game for its emphasis on entertainment rather than the chance to win money.

Some of the most popular video slot games include:

  • Legacy of the Dead
  • Sweet Bonanza
  • Wolf Gold
  • Book of Dead
  • Starburst

Progressive Slots

Finally, progressive slots is an online casino game with many fans due to the chance of winning massive amounts of money. The premise of video slots is quite simple; as more players make bets, the more money gets added to the jackpot. Some progressive slot games pay millions, whereas others might be between $25,000 and $250,000.

Unlike multi-line slot or video slot games, progressive slots could be traditional, multi-line, or video. They may have bonus features like free spins with 100s of pay lines, or they could have 3 reels with 1 pay line.

The main attraction to progressive slot games is the chance to win life changing amounts of money and the thrill that comes with that.

Some of the most popular progressive slot games include:

  • Mega Fortune
  • Mega Moolah
  • Gladiator
  • Joker Millions
  • Treasure Nile


Which is the Most Popular?

It’s difficult to determine which type of slot game is the most popular as this might change over time. However, video slot games are typically the most played at online casinos because they focus on providing entertainment, which is one of the main reasons why people play them.

That being said, multi-line slot games also have a dedicated player base and are quite popular because they allow players to win more frequently. Traditional slot games also have a loyal player base due to their simplistic nature and associated nostalgia.

Depending on your mood, preferences, and how lucky you feel, you would likely play all these slot games over the month.
