How to win slots?

Understanding slot machines

There is hardly no way around slot machines when visiting online casinos. Slots are highly popular among all players due to their easy rules while still keeping the players entertained. Although the rules of slots are pretty straight-forward, we want to explain you the basic features and function to give you a head start.

Free Spins – bonus or slot feature?

Fans of slots already know the deal: free spins are the bonus type used in slot machines. Free spins allow players to spin the reels for a certain number of rounds without touching their bankroll. While some online casinos offer free spins as part of their dedicated casino welcome package, others grant this type of bonus on special occasions like a new game release or alike.

Free spins should not be confused with the free spin function some online slots feature. The free spin feature in an online slot is activated when combining certain symbols and can be seen as an extra spin on top of the “regular” spin/bet. This feature is one of the most common features in slot games and you will find it in various games from different provider.

Wilds, Multipliers and Scatters

Classic online slots work with rather simple symbols and usually do not offer any bonus features. As the online gambling market is rather competitive, game providers are seeking to create existing new games with interesting game features and bonus functions. One major innovation in the world of slots was the introduction of additional symbols, the so-called scatters and wilds. Both symbols can be highly beneficial to slot players, they just need to understand how they function.

Wild symbols – expanding, stacked and more!

Almost every modern video slot uses wild symbols. These symbols are “wild cards”, which means that they can substitute any other symbol of the game. This automatically increases the chances of winning as the wild symbol replaces any symbol that might be missing to create a winning line. Wild symbols can also trigger other bonus functions like expanding wilds or even bonus rounds. All these events can lead to higher winnings! So, keep looking for the wild symbol when spinning the reels of your favourite video slot machine.

Scatters – the most valuable slot symbol?

Scatter symbols are any video slot players favourite as they can win you big once they appear anywhere one the reels. This symbol is one of the highest paying symbols and triggers any bonus feature such as free spins, a bonus game or any other bonus the game might have. As mentioned before, scatter symbols are unique as they do not have to appear on a win line in order to benefit you. Especially when playing on a slot with a progressive jackpot, scatter symbols can get you big returns on your bet.

Multipliers – double your winnings!

Multipliers – as the name suggests – are symbols that can significantly increase your winnings by two, three or even ten times. Multiplier symbols can appear anywhere on the reel and can give players, who have only placed a bet with a rather small amount, huge returns. Usually, these symbols are only used in bonus games or during free spin rounds, however, some slots also feature them in the main game.

Bonus Rounds – Free spins, mini-game and more!

Bonus rounds are a popular bonus feature within video slots and can vary in their form. Free spins are the most common bonus round feature, however, there are also other types like a bonus game or a risk option. The bonus game/round feature is unlocked when the bonus symbol appears on the reels or a certain goal specific to the game is achieved.

A bonus game or bonus round presents punters with the chance to not only increase their winnings but also discover the interesting layers of the game. While a bonus game is a mini-game within the video slot, bonus rounds usually happen in the main gameplay.

Slot Strategy - Win

How to play slot games successfully?

It is no secret that there is one thing you need to win at any casino: LUCK. All games provided in an online casino work with the so-called RNG (Random Number Generator), ensuring that everyone has the same chances of winning. Consequently, there is no set strategy that guarantees winnings, however, you can take certain steps to improve your chances!

1. Pick your preferred slot

Most online casinos offer a wide variety of online slots, with different designs, themes, and game play. If you are not sure what slot machine works best for you, play them in “fun/demo mode” until you have found your favorite. Not sure where to start? Check out the Top 10 video slots in the table above!

2. Check the pay-table

Looking at the pay-table should be the first thing to do when opening a video slot. The pay-table lists all the important information and will give you on overview of all winning combinations, including the winning amount. Moreover, wild and scatter symbols will be explained for you to understand their function in the main game plus the bonus game. Besides symbols, pay-tables also include information about progressive jackpots, if the video slot features one.

3. Set your bet amount – coin value ≠ bet

Online slots give casino players the chance to adjust their bet amount to their needs or willingness to risk. Punter just have to set the coin value to their desired amount in order to increase or lower their total bet. The coin value is always multiplied by the number of pay-lines. This means, if the slot has a total of 20 pay-lines and you set the coin value to 0,01, your total bet amounts to 0,20 euro.

4. Start the game – SPIN!

Once you have completed all previous steps, it’s time to hit the spin button and keep your fingers crossed! If you do not want to click the spin button for every new spin, you can click on the auto-play button and choose the amount of your desired spins – the reels are now rolling automatically.

5. Keep your bankroll in check

While spinning the reels of an online video slot is very exciting and fun, players should also keep an eye on their money. Our advice is to set a maximum amount you are willing to play for before starting to hit the spin button.

Frequently Asked Questions - video slots, classic slot machines
Can I play online slots for free?

Yes. Almost every online casino offers players the option to spin the reels of their favourite online slot “for free”. The so-called “demo mode” or “fun mode” allows players to check out the slot before using their own funds, however, players need to realise that they cannot win real money when playing “for free”.

Are online slots really random and fair?

Yes. Online slots provided by trustworthy online casinos use a so-called Random Number Generator (RNG) to always ensure the fairness of the slot. The RNG generates random numbers that do not follow any pattern, giving all players the same chance to win.

What is a progressive (jackpot) slot?

Progressive slots work just like any other slot. The major difference is, however, that every time a player places a bet on a progressive jackpot slot, a small amount of this bet is added to a jackpot. The more people spin the reels and wager, the higher the jackpot gets. Progressive jackpot slots are very popular as players have the chance to win big with just a small bet.
