Many different types of slot machines can be found in online casinos. The most popular type is video slots, which usually have five reels and a variety of symbols, including wild and scatter symbols. Other popular slots include progressive slots, reel slots, VR games, 3d, live slots, and other thematic slot machines.

Slot machines with a progressive jackpot

Jackpot slots.

Progressive slot machines are casino games with a jackpot that increases over time. The longer the progressive jackpot goes without being won, the higher it will get. This means that games can potentially pay out very large sums of money. Moreover, they all work essentially the same way.

Playing slot machines with progressive jackpots, a part of your bet goes into the jackpot. The more players playing the game, the higher the jackpot will be. Progressive slots can be found in both online and offline casinos.

If you are interested in playing this type of casino game, you must find a casino that offers them. At 50-spins.com, I collect a list of casinos that offer progressive slot machines. Once you have found a casino that offers it, you can compare the jackpots and decide which slot game fits you. Moreover, I have a list with 50 free spins as a bonus for casino players.

You should also remember that games with progressive jackpots can be very volatile. It means that the jackpot can go up or down a lot in a short period. If you are uncomfortable with this type of volatility, you may want to stick to playing other online slots. Progressive slot machines can be fun to play for money. They can also be very lucrative if you are lucky to hit the jackpot.

Reels in slot machines

As I mentioned before, gamblers can choose between many types of online slot games. You can see it in FairGocasino. One of the most common is the reel slot machine with several symbols, including wild and scatter symbols. Choosing games online, you’ll see they can have three to five reels with limited paylines. This means that there are a limited number of ways to win on these machines. However, they can still be fun and offer some good payouts.

Megaway slot machines

Megaway is a technology for video slots with six reels instead of five. Megaways have become increasingly popular due to their higher potential payouts. You may want to know that Big Time Gaming created this type of slot machine for online casinos and shared it with other software providers. Here are some examples: Wild Portals, Pirate Pays, KingMaker, SlotVegas, and Who Wants to be a Millionaire.

3D slot machines

3d slot machines.

3D slots are a moderately new expansion to the universe of online gambling, and they offer an outwardly improved gaming experience compared to classic slot machines. The games are planned with three-layered illustrations and movements that create more vivid and engaging entertainment for players.

As for me, one benefit of 3D casino slots is the degree of detail of the games. The illustrations are more exact, and the movements are smoother and more liquid. This makes the game more pleasant to play.

One more advantage of 3D slot openings is the expanded interactivity. Some 3D games have extra highlights like bonuses and risk games that give players an opportunity to win more playing for real money. I wouldn’t say that these elements can lead you to greater payouts or more chances to win because it’s just a design in the end. However, the gameplay and winning combinations can be more enjoyable.

Numerous 3D games have exceptional elements, such as extra games or free spins. I can also say that Betsoft Gaming is quite possibly the most famous game provider that produces 3D slots to play online. Most well known are: Reels of Riches, Legend of the Nile, Fa Twins, and The SlotFather.

In summary, 3D slots give you a completely new experience, unlike classic slot machines. While they may not be everybody’s favourites, they are worth going for players who appreciate attempting new features and investigating new types of casino games.

Live dealer slot machines

Live dealer games are a new type of slot machine that allows players to interact with a dealer in real-time. These dealers can be located anywhere globally, making live dealer casino games a truly global experience. Players can chat with the dealers and other players, making for a more social experience. Evolution, the most popular casino provider, created games: Lightning Blackjack, Poker, Bac Bo, Monopoly live, Mega Ball, Bingo, etc.

Thematic slot machines

  • Fruit. Themed around fruits are symbols such as cherries, lemons, and oranges.
  • Jewellery. Themed around jewellery has symbols such as diamonds, rings, and necklaces.
  • Movie. Themed around movies and uses symbols from popular movies or TV shows. For example, Terminator 2 and Iron Man.

Jewellery, movies, fruit, or other thematic slots online can be found in online and offline casinos.

Land-based slots

Land based slot machines.

Land-based slots are games in a casino or other places where it is allowed. They have been a staple of land-based casinos for a long time and are still famous among players today. Here are a few upsides and downsides of playing them:

The bottom line is that land-based slot games offer a completely different way to enjoy gambling. Yet they truly do have a few disadvantages. Players should gauge the advantages and disadvantages before playing offline or online.

VR slot machines

VR slot machines.

Our next stop is VR slots, which are somewhat new to the online gambling world. They use computer-generated reality innovation to make it more vivid and practical for casino players. Without a doubt, these slot machines show players various universes of entertainment. Here are a few pros and cons of playing VR online slots:

In summary, VR casinos show an interesting and unique experience but also have issues. I recommend that you consider all the features associated with VR before you start playing. On the other hand, I’m sure this is the future.

Slots with Buy Bonus feature

Bonus Buy slot feature.

Buy Bonus is one of my favourite features that appears in online slots. The Buy Bonus feature allows players to buy access to the bonus round without waiting for it to trigger through gameplay. Below I’ve written some pros and cons of playing casino slots with Buy Bonus features:

In summary, the Buy Bonus feature can be useful for those who want to increase their chances of winning and save time. On the other hand, it can be expensive to pay several tens or hundreds of dollars at once. According to my experience, payouts sometimes may be less than what I paid to start the bonus round. Nevertheless, I advise you to read the pros and cons before deciding whether to use the Buy Bonus feature.

Slots By Payout Frequency

Payout frequency is the most important part of video slots. Slots by payout frequency is about games that pay out winnings frequently but in smaller or less frequently but in larger amounts. I’ve written some pros and cons of playing slots by payout frequency that you can use during your decisions:


  • Set a budget: I strongly recommend that before playing slots, set a budget and stick to it. This can help you avoid overspending and losing more money than you can afford.
  • Choose games wisely: Before playing, I spend much time researching online slots by payout frequency and choosing what fits my personal preferences. At the same time, some players prefer the thrill of high-volatility games with high risk. While others prefer the steady payouts of low-volatility games.
  • Manage bankroll: Managing bankroll is like a skill for players. In high-volatility games, you should be prepared to lose, while others may need to spin the reels much longer to build their bankroll at increased bets.

Slots by RTP

Talking about types of slot machines, I couldn’t miss tread with RTP. Slots RTP is a percentage of money a slot machine will pay back to players over time. For example, if a casino slot has an RTP of 95%, it means that for every $100 wagered, the slot will pay out $95 in winnings. I recommend playing slots with at least 96%. Below I made a list of pros and cons of playing slots with high RTP, along with some tips for players:


  • Choose games with high RTP: I will repeat it again and again. Research different slot machines and choose only those with a high RTP. My rule is to look for games with 96% or higher RTP.
  • Manage bankroll: Yes, I’m talking about bankroll again and want to tell you that even playing slots at high RTP, do not forget to manage your bankroll.
  • Play for fun: I understand that winning money is always our main goal. On the other hand, slot machine games should primarily be for fun and entertainment. Don’t hesitate to start to spin slots for free.

In summary, traditional slots or more modern with high RTP offer better chances to win and more consistent payouts. However, much information is needed before playing for money and being successful. Choose games wisely, manage your bankroll, and remember to play for fun.
