Slots are the most popular casino games in online casinos due to their simplicity and easy-to-understand rules, even for beginners. The mechanics involve spinning reels to change the positions of symbol rows. Slot machine outcomes are determined by a Random Number Generator (RNG), which uses a program to select random groups of numbers and produce winning or losing symbols.

Players can achieve high winnings with low stakes and minimal risk. The selection of games in this category is vast. Additionally, every online casino website offers hundreds of slots, ranging from simple and classic variants to ultra-modern progressive jackpot slots. The variety of themes is virtually endless, catering to every player’s taste. Furthermore, playing slot games for free is the best option before choosing games to play for real money.

Design of Slot Machines

The best online slots consist of numerous symbols that land on rows and reels when the Spin button is hit. The reel arranges the symbols vertically, and you can see the game symbols horizontally on a row. Classic slots have 3 or 5 reels and 3 rows. However, modern games can display other compositions of reels and rows. The main buttons used for playing are:

  • Bet button – for setting a bet per spin.
  • Paylines button – for setting the number of paylines per spin.
  • Spin button – for starting a spin or a game round.
  • Autospin – for selecting a certain number of automatic spins.
  • Info button – for learning information about a slot, the payout rate of a game and each symbol. You can also see what special features are available in the game.
  • Settings – for setting the volume and other options for the game.

Depending on the slot game, there may be other buttons, but these are the most commonly used.

Symbols and Special Features of Online Slots

At first glance, all the slots often look very similar. Though, if you take a closer look, it becomes clear that the differences between various games can be immense. Many slot designs and concepts exist depending on the game developer and the type of player the game is generally intended for.

If you look at the structure of a slot machine, the following elements form the basis of the game:

  • Reels. The reels are the vertical columns of a slot. The most common games are those with 3 or 5 of these reels.
  • Rows. Here we are talking about the horizontal rows – mostly, you will find 3 or 4 rows depending on a chosen slot.
  • Paylines. The number of paylines on a slot machine refers to the specific places where combinations of characters must appear to count as a winning combination. Online Slots differ greatly on this point. Paylines range from a single line to up to 20-25 ones.

But, of course, the structure is not the only point in which various online slots differ. Thus, the following features of a slot machine game display a lot about the type and nature of the game:

  • Wild Symbol. It acts as a wild card, which can stack with other symbols and help create winning combinations.
  • Scatter. It helps to trigger wins even without lining up on an activated row.
  • Multiplier. Depending on the game, a multiplier can come in free spins or other winning combinations. There are no limits to the creativity of game developers.
  • Free Spins. It can be awarded to a player after a spin without a need to make an additional bet.

The Most Popular Slot Themes

The variety of best slots to play online is staggering. They differ not only in features but in a variety of themes. Here are the top 6 most popular slot themes:

  • Adventure: Of course, the most diverse slots can be found under the adventure theme. What do they all have in common? An exciting adventure at the center of the game. It doesn’t matter whether it’s about Jack and the Beanstalk or the latest adventures of Batman. Adventure remains adventure – thus, it is one of the most popular slot categories.
  • Fruits: Fans of classic games will surely appreciate the traditional fruit symbols. In such a theme, fruits are combined with other classic symbols like stars, sevens or bells, creating simple and cheerful fruity gaming pleasure. This theme category includes most of the 3 reel machines, as in the majority of cases, they bring a classic theme choice in addition to a classic structure.
  • Egypt: The Egypt theme is rightfully at number 3 on the theme hit list.Pharaohs, hidden treasures, pyramids and mummies – you hardly need much more for an exciting slot. Sand and desert and a mystical atmosphere perfectly round off the Egyptian gaming pleasure in most cases.
  • Underwater: In this category, the various shades of blue usually dominate. In the underwater-themed slots, you will encounter breathtaking natural environments and various sea creatures in light or dark, deep waters or calm lakes. And yes, in the slot world, there are also mermaids involved. In addition, of course, plenty of fish are waiting – you can even meet the celebrity Nemo in the virtual gambling action.
  • Fairy Tale: Whether it’s Hansel and Gretel or Jack and the Beanstalk, fairy tale themes are extremely popular in slot machines. Wonders are guaranteed to players here.
  • TV and movies: Almost all the well-known characters from TV series and hit movies can now be found in online gambling. Southpark, Batman, Dracula, and Spiderman are among the most popular slots. In addition, hundreds of other games are now based on TV, film and show business celebrities.

Of course, there are also many other themes, such as games that deal with animals, fairy tales, science fiction, or even the dream of America. The list is endless – and guarantees that there is a suitable slot for every taste and occasion.

Choose a Slot Type to Play

Different players often prefer different types of slots that are also suitable for different moods. The characteristics of each type of slot machine are unique. That is why we decided to gather the most popular and frequently played types of games in the online gambling industry.

  • Classic slots – Casino games designed after the one-armed bandit, mostly set up with 3 reels and only one payline. Old slot machines were the model here.
  • Video Slots – These online slots real money have evolved with technology to suppliers of great graphics, soundtracks, free spins, bonus features and other impressive extras. The variety of themes is staggering and hardly leaves out any division.
  • 3D slots – They can be seen as a technical advancement of video slots. Rousing animations, enhanced graphics, and multi-level bonus rounds that involve a player often occur amidst an all-encompassing story that brings a player to other worlds.
  • Progressive Slots – Games with jackpots linked to the actual games gamblers play worldwide and are therefore constantly increasing are referred to as progressive games. They offer the largest possible winnings – sometimes even millions. Of course, these are usually not available for free play.

The Best Slots to Start

Despite the large selection of games in online casinos, there are some popular games that never get boring. Some of them were way ahead of their time when released and have had a lasting impact on the gambling industry. Many slot machines that are new to the market are based on the old classics. Below we list a few of these very special best online slots that new gamblers should know about.

Book of Ra

Book of Ra was developed by the game manufacturer Novomatic and has then set new standards. It was the first book game ever. In the ancient Egyptian ambience, you chase after the books that trigger 10 free spins each. The highest symbol is the explorer. If you get 5 of them in the free spins, you’ll reach the highest possible win of x5000. The overall gameplay and sound still trigger nostalgic moments for many players today.

Book of Dead

Book of Dead is almost the same game as Book of Ra. The game is published by Play’N GO and is still one of the absolute classics. In almost every online casino, this game is listed as one of the most played slots. Players are offered to chase after the books in ancient Egypt settings. The good sound and the game’s speed also add to the fun.


Starburst is a futuristic slot with expanding wild reels. When a wild symbol appears on the second, third or fourth reel, it expands, and a re-spin is triggered. This means that up to three wild reels can appear on the screen at the same time. And the best part is that wins are counted from both sides. The symbols consist of gems, bar symbols and a 7 symbol. Both sound and graphics are top-notch. The only drawback is that there is no free spins feature.

Eye of Horus

Eye of Horus is also a classic that has spawned a whole new game concept. The theme here is ancient Egypt. As soon as you get at least three scatters, 12 free spins are triggered. Once an expanding wild symbol appears during the free spins game, an additional spin is awarded, and the lowest high symbol is removed. If you make it to the end, all high symbols will be converted into the highest symbol, increasing the chances of winning.

Mega Moolah

Mega Moolah is a 5 reel slot with 25 paylines. The theme is African animals. Giraffes, lions, elephants and other inhabitants of the sunny continent serve as symbols here. There is a free spins feature where you can win big. But the special thing about this slot machine is the enormously high jackpot. Here you can win several million in one fell swoop for just a few cents.

Real Money Slot-Playing Strategies

There are thousands of slot games and themes to choose from, and the choice is yours. However, you should pay attention not only to the graphics, special casino bonuses and exclusive promos, but also consider the type of slot player you are.

Low Rollers

As a low roller, you typically enjoy playing the best online slots for extended periods without placing large bets. It’s advisable to try classic slots, such as 3-reel fruit slots or 5-reel slots that allow for low stakes. You should also focus on slots that offer smaller jackpots, as a lower jackpot value makes it easier to win with a small bet. Seek out slots with low volatility or variance. The smaller the allowed coin size for wagering, the longer you can enjoy playing.

Mid Rollers

If you are a mid-roller type, you play because you enjoy it. However, you probably realize that you will often get smaller winnings and can only occasionally pocket larger ones. Your budget is a bit bigger than a low roller, and you like to bet a bit more. With medium volatility slots, you get the opportunity to get a smaller win more often.

High Rollers

If you consider yourself a high roller, you’re willing to take high risks and may have a more substantial player budget. You don’t mind experiencing long dry spells without any wins, even small ones, over multiple spins.

You understand that a high and consistent bet can potentially yield lucrative winnings. It’s recommended to try slots with high and preferably progressive jackpots, as these cater to your preferences. Slots with progressive jackpots typically have the highest volatility, presenting you with the highest risk.

The Best Online Slots Providers

There is now a wide variety of game providers. Some have been associated with online casinos since their inception and have expanded and improved their game selection. The best slots are becoming increasingly innovative, from Megaways Slots to bonus buy features. You will consistently find certain game providers in online casinos that deliver high quality in terms of exceptional graphic design, game mechanics, or sound.

Below is a list of some providers you should pay attention to. These game developers have years of experience in slot development and are among the leading companies in the gambling sector.

NetEnt Slots

NetEnt is a Swedish slot manufacturer that has been on the market since 1996. This company has produced many classics, and slots like Gonzo’s Quest or Starburst are just the tip of the iceberg. Hundreds of games have been developed by NetEnt and are still very popular. Even big movie names like Vikings used NetEnt for the slot adaptation. NetEnt slots are therefore represented in almost every online casino. If you want to convince yourself of the quality of the slot machines, you can play the slots for free. No login or registration is necessary; select a game and start your demo.

Microgaming Slots

Microgaming, founded in 1994 and based in the Isle of Man, is a slot manufacturer renowned for developing highly innovative slots. Movie adaptations are particularly popular among its fans. Jurassic Park, Game of Thrones, Top Gun, Robocop, Marilyn Monroe, and numerous other well-known blockbusters and film actors have been incorporated into the virtual world of slot machines, thanks to Microgaming. Players have the option to enjoy free versions of Microgaming slots or play with real money.

Pragmatic Play Slot Machines

Surprisingly to some, Pragmatic Play was founded as recently as 2015. Nevertheless, the game provider has become an essential part of the casino scene. The manufacturer has already released hundreds of online slots for real money, covering a wide range from jackpot slots to Megaways slots. Some games also offer exclusive bonuses and extra features. Among the most well-known titles are Dog House and Madame Destiny.

Bonuses and Exclusive Offers for Online Slots

Online casinos offer numerous promotions, which is the best way to start playing. Here are the most common options:

  • No deposit bonus: when registering at a casino without depositing real money, you either get free spins on one or more slot machines or a money bonus that you can use in the casino.
  • Welcome bonus: for the first several deposits, you’ll receive a certain percentage of bonus money (e.g. 100% bonus up to €250), which doubles or multiplies your stake. There are also free spins or a combination of free spins and a cash bonus.
  • Slot reload bonus: it becomes available for new deposits of the existing customers if the welcome bonus has already been activated.
  • CashBack Bonus: some casinos will credit certain sums to your account even if you lose a streak; that’s how brands motivate users to keep playing.

The best way to get to know a new online casino is, without a doubt, by taking advantage of a free bonus. To do this, you can register at a few casinos and start playing. Even more, many casinos offer free slot machine games without registering first.

Play Slots Online – Odds of Winning

There has always been a question about tips that improve your chances of winning online slot games. Unfortunately, the answer still remains the same: winning real money in slot machines is only possible through luck and chance.

Nevertheless, here are some tips you can use to improve your gaming fun:

  • Playing slots for free is a fun pastime without any financial risk. Besides, by using demo versions, you can also prepare yourself thoroughly for playing with real money.
  • Another nice option is the no deposit bonus, allowing you to test a casino and some games for free.
  • If you want to play slots with real money, you should always pay attention to the RTP rate. Even if it is just a statistical value, it shows the basic tendency of the slot machine.
  • It is better to play all available paylines with a small bet instead of choosing just a few paylines with a high stake.
  • Using risk gamble judiciously can be a good strategy to refresh the account here and there.
  • You should definitely play in a slot using selectable strategies because they save a lot of time.
  • Anyone who practices good spending management is safe from unpleasant surprises. You should set a fixed budget and play, so you won’t get lost in your enthusiasm.

So choose your prefered theme, don’t forget to claim a bonus and remember that the outcome of the game depends on a Random Number Generator (RNG), and there are no other ways to influence the game.
