Starburst is one of the absolute all-time favourites among casino slots. The popular NetEnt slot has been bringing excitement to players since 2012 with an RTP of 96.1% and a maximum chance of winning 500x bet – with a maximum bet of €100, that is €50,000. The wildcard bonus system makes Starburst particularly attractive, as it increases the winning options.
Starburst has 5 reels, 3 rows and 10 paylines. Bets are possible between 10 cents and €100, thus making the slot suitable for most players. The slot looks futuristic with colourful gems graphics and galactic sound effects.
The game is easy to understand, thanks to the low volatility you win frequently and the features, such as Free Re-Spins or Expanding Wilds, make it especially entertaining. Many online casinos offer Starburst free spins as part of their welcome bonus.
The goal of the slot is to spin at least 3 identical symbols. Thanks to the Win Both Ways feature, you can get a winning combination from left to right and from right to left.

The slot with the theme of Egypt has high volatility, meaning you win less often, but the prizes are higher. Risk games also give you a chance to multiply a win.

Online Slots Software Providers
In addition to a diverse selection of online slots, there is also a whole range of software manufacturers. Some are known for their unique graphics, others for their fancy ideas. Some focus on live games, while others developed slot machines for classic casinos already 50 years ago.
Below, we'll introduce you to three great providers who keep attracting us with their slots.
Yggdrasil
The Swedish game developer has only been on the market since 2013 and is thus still relatively young. Nevertheless, it has already been able to make a name for itself in the industry and impresses, especially with its innovative games.
The quality is excellent. This is why Yggdrasil has already developed into one of the best manufacturers in its relatively short history. The provider has also won various awards, for example, Slot Provider of the Year 2017 at the EGR B2B awards.
Some of the top casino slots from Yggdrasil are:
- Jungle Books
- Vikings go Berzerk
- Orient Express
Thunderkick
Thunderkick was founded in 2012 with the goal of providing a better online casino gaming experience. This has been achieved: Its slots convince with above-average winning chances and completely new ideas and game concepts.
The software manufacturer takes a lot of time for the development of its games – quality clearly comes before quantity. There are only about 50 games, but they all impress with their innovative features and great graphics.
Some of the most popular Thunderkick slots are:
- Pink Elephants
- Tiger Rush
- Midas Golden Touch
iSoftBet
iSoftBet was founded in London in 2010 and now offers over 300 games. The developer is known for its branded slots based on TV series, movies or books.
iSoftBet is licensed in over 19 regulated casino markets and is responsible for the GAP software, through which online casinos can provide over 3,000 games from over 30 manufacturers.
Among the top slots are:
- Paranormal Activity
- Book of Immortals
- Majestic Megaways
Alternatives to Online Slot Machine Games
Slots are the classics in online casinos, but there are also several table games and other alternatives that are just as fun.
Feel like trying something different but don't know what to choose? We will introduce you to the most popular alternatives to slot games.
Roulette
Roulette is definitely one of the most popular gambling games ever. Players place their bets before the croupier throws the ball into the wheel. The goal is to bet on the right number, colour or combination.
There are quite a few different variants, so you certainly won’t get bored. In addition, many roulette strategies can be used to approach the game a little more strategically.
Blackjack
This popular card game is all about beating the dealer and getting as close as possible to the card value of 21 with two or more cards. You have a blackjack if you reach 21 points with the first 2 cards.
Numerous online variants of this classic game provide variety. Also, there are several blackjack strategies that you can learn and try. So if you don't want to rely on pure luck, blackjack might be a good alternative to slot games.
Poker
Another great alternative, if you want to rely on something other than luck, is poker. Here you can improve your chances with the right strategy – provided you're good at bluffing!
There are also video poker slots. Here you don't have to be a professional and know the rules in detail. Moreover, the RTP of these slots is usually very high.
Baccarat
Another card game is baccarat. It is considered one of the simplest casino games and is easy to understand.
Again, you are not playing against other players but against a dealer. You can make three main bets: a player’s hand, a banker’s hand or a tie. The hand with the highest score wins. In baccarat, this is the total score of nine.
The numbered cards correspond to their numerical value. Jack, queen and king are worth 0 points, an ace 1 point. As soon as you exceed 9 during the game, you start counting from 1 again.
Dice Games
There are dice alternatives if you don't like playing card games. They are especially suitable for players who don’t want to learn special rules or strategies. In the dice game, you usually bet on a certain number of dice – so you can get started easily and without experience. A popular dice game in a casino is craps.
Live Casino
If classic online casino games don't convince you, you should check out live casino. Real croupiers and real-time game playing create a different feeling.
Most virtual casinos also offer live versions of classic table games. In addition, there are exciting game shows and now even some live slots.
5 Principles of Online Slots
Play only in licensed casinos
The most important principle to be followed in all games is to play in licensed casinos. Only in this way can you be sure that providers abide by the rules, games are fair, and winnings are paid out.
Understand the game
Before you get started, be sure to understand the game. By this, we mean not only the machine itself but also the principles of slots in general. For example, find out what RTP and volatility are all about so you can choose the right slot machine and understand how it works.
Choose slots with a high RTP
The higher the payout ratio, the more deposited real money is paid back to the players. Make sure to choose slots with an RTP of over 96% to increase your chances of winning.
Try slots online for free
If you are not familiar with a slot yet, use a free demo version to test a machine with play money. This way, you can develop a feeling and see if it is really the right one for you.
Have you found the perfect slot? Then take advantage of bonuses and free spins to win without even depositing your own money. However, pay attention to the wagering requirements.
Keep in mind that this is gambling
Online slots are and remain gambling. Remember that winnings are not guaranteed, and even with the best tips and strategies, you won't necessarily win. Use online slot machines as a fun pastime, but never to make money.
Play responsibly, set a budget and stick to it. Many casinos also offer the possibility to control your gaming behaviour by setting different limits or a cool-down period.
