How to Win Real Money at Slot Games?

If you want to bet real money online and win big sums of cash, you need to learn how to play online slots. At first, it may seem straightforward and effortless, as you simply press the spin button. However, it doesn’t make you the winner, and you potentially can lose a lot. Before you start to play slots online in casinos betting real money, you need to understand that slot machines work completely randomly. This means every player has a fair chance to win a jackpot. Luckily, there are a couple of tips and tricks to improve your chances of winning real money in online slot games.

Step number one is to realise that slot machines are programmed similarly; however, some differences play a huge role in helping you land a big reward.

The Mechanism of Real Money Slots

The real money slots deliver a fair game to every player regardless of the slot games. Every online slot machine at a reputable casino uses what is known as a random number generator (RNG). RNG makes sure the outcome of your game is illogical, unreasonable, and unpredictable. This means there is no way to cheat the system and get ahead of everyone else. Every casino with online slot machines maintains and checks the system regularly; thus, there is no way to legally trick the slot machine. Instead, there are other ways that can help you increase your chances of winning.

How to Increase Chances in Winning Big at Any Online Slots Casino?

You can find the best online slot machine and still work hard on winning a big reward. And, more often than not, you will lose most of your bet because you either chose a slot machine with a low RTP (return to player) percentage or you are not betting enough to be eligible for a win, among a few other factors. These details can greatly change the outcome in your favour. Even though you don’t need to master a skill to play slots online, you need to be selective and make smart decisions, especially betting on real money. Here are some tips that will help you win more money at your next slot game:

Claim All Bonuses

If you are only a beginner and do not know where and how to play online slot games, you have a great chance of receiving a welcome bonus. A welcome bonus may include some slot credits to play and free slots – this is a great opportunity to play a couple of online slot games and see how they work. Later, depending on the slots casino, you can receive various boosters, deposit bonuses, and other things during different events.

When it comes to in-game bonuses, they also depend on a slot machine. Some slot games have different payout lines, some have symbols that add an extra free spin, and other bonuses.

Limit Your Budget

Once you register your account and claim bonuses, it is crucial to set an amount of money you can spend per online slot game. Since you are betting on real money, you don’t want to spend too much; otherwise, it may lead to grave circumstances. An online slots casino is a means of entertainment, and gambling should be responsible and reasonable. In some slots casino account settings, you can limit your spending and deposit amounts to prevent significant losses. This is a helpful setting for those who tend to take risks.

You will only enjoy playing real money slot games if you are aware of your bankroll. There is an abundance of online slot games that can fit your budget, too.

Whether you are a beginner or a professional, you should keep in mind that gambling is not a way of earning money. This means that once you start losing spin after spin, it is best to give a break rather than work on winning back the money.

Check RTP Percentages (Return to Player) of Online Slot Games

When playing online slots, you increase your chance of winning in comparison with real land-based slots; on all of the online casinos tested by our team you can always benefit from great free spin bonuses when making your first deposit! Have a look at the most attractive free spin bonuses of the moment here to be able to spin for free on one of the thousands of online slot machines available. The RTP percentage of an online video slot is 93% on average, which means that for every 100 euros wagered on slots at an online slots casino, an average of 93 euros goes back to the player. The RTP percentage of slots in a land-based casino is a lot lower; the RPT percentage in land-based casino slots is 84% on average, which is considerably lower. That is why it is wiser for you as a slots player to win real money playing online.

RTP is used in quite a few casino´s to measure your chance of winning in the game. Imagine that a slot has a payout percentage of 92%, of course, you would assume that for every 100 euros you wager, you would get back 92 euros. However, in real life, this turns out to work in a different way than you might expect. The RTP is calculated and based on very large numbers, so it could be that if you wager 100 euros on an online slot game, you could immediately win a huge jackpot prize in the millions. But, on the other hand, you might only see 20 euros of the 100 euros you have wagered back. In other words, the RTP ( return to player percentage of payout percentage) is the average of millions of spins and bets.

Be Eligible for a Win

There are many slot machines that award big rewards; however, to be eligible to win them, you need to make a worthy bet. The reason why the rewards continuously increase in slot games is that players make small bets. If you want to win, you need to make a higher or a maximum bet in a slot game, but only if you can afford it. Making a bigger bet in an online slot game increases your odds of winning a jackpot.

Determine the Variance of Online Slot Games

The variance, or volatility, of slot games, can be either high or low. And there is no way of knowing the truth since the developers do not reveal this information anywhere. You can read about a particular game online and check the previous players’ comments and discoveries.

High variance means the rewards are big; however, it is harder to win them. In contrast, low variance means smaller rewards but more frequent.

The online slot games with low variance are a perfect option for people who prefer to play small and safe. While real money slot games with high variance are an ideal choice for players who like to take risks, have patience and resources.

If you are wondering which variance you are playing at, you can read comments of previous players, observe the game and try to see the patterns, and note how often and how big is the payouts are.

Read Guidelines and Instructions of an Online Slot Game Before Playing

Every slot game is different in its gameplay, so before you bet real money online, make sure to have a look at the instructions. Playing blindly will cost you a lot, so it pays to understand the rules. The rules will help you understand how you can land a win, what symbols or numbers you need on reels, how to align them, and what various features mean. This way, you will know what combination to bet on and how much.

The most popular symbols you can see on reels are Wild and Scatter that grant you a bonus game or another bonus before the next spin. There is also Sticky that remain on the reels for the next spin, increasing your chances of winning a reward.

Types of Online Slot Machines

There are different types of slot machines that have small and big rewards. Below is the list of the most popular slot games that you should play online to understand which one suits your preferences. Each of them has its own characteristics and unique gameplay. Once you find your favourite slot game, you can master your knowledge of it and increase your odds of winning. There are hundreds of slot machines that can also fit your budget.

3-Reel Slots

3-reel slots were the very first ones to appear on the casino floors, they are retro, and they are still popular, although a bit outdated. The 3-reel machine has 3 rows, and you can win only when three identical symbols are aligned in a row. There are of a low velocity, meaning you can often win small amounts.

5-Reel Slots

New technology allowed slot machines to be brighter, funnier, and diverse. In order to elevate the level of entertainment and increase the number of rewards, 5-reel slots were invented. From the name, it is clear that these slot game machines have 5 rows, but also there are more payline combinations available. This means there is a higher chance of landing a reward. In contrast to slot games of the previous generation, 5-reel slots can be both of low and high velocity; thus, the reward amount can vary.

Unlike a 3-reel, a 5-reel slot game has more interactive and engaging gameplay, new features, and bonuses, for example, Scatter, Wild, and many others.

Video Slots

Similar to 5-reel slots, video slots are very interactive, loud, and have engaging gameplay. The only difference is that there are no reels. Video slots are digitalised, and they can have slots with up to 7 reels. They also have several paylines and special bonuses.

Multi-Payline Slots

If you are looking to maximise your earnings, you might try to play slots with multi paylines. Remember to always check what paylines are applicable, which ones you can bet on, and in time, you will discover the most profitable ones. With multi-payline slots, the combinations are not limited to horizontal and vertical lines; they can be diagonal or simply a set of symbols. Depending on a slot game, you can bet a little on every possible payline, or you can select two-three of them and bet bigger sums.

Mobile Slots

Mobile slots are perfect for people who want to play slots but do not possess a personal computer. Mobile slots are available for devices like smartphones and tablets. It is also convenient for those who are always on the move. Mobile slots are no less interactive, they are constantly regulated, and they also use a random number generator that delivers a fair game to every participant. Depending on the online casino and the slot machine, all games should be available for both Android and iOS users.

Progressive Slots

Progressive slots are one of the most attractive slot machines at casinos. All because of the reward that doesn’t stop going up. Little do gamblers know that reward keeps increasing because of the small bets they make. Progressive jackpot slots are the hardest to win because the reward is so huge it is paid seldom. And if you want to try your chances, you need to make a bet worthy of being eligible for a win. Otherwise, you simply lose money, and the slot game automatically disregards your bet.

There are different progressive slots with various values and maximum rewards, and it is recommended to aim at lower rewards as they are paid more frequently.

Other Slots

Some of the best online casinos have unlimited options for slots that greatly vary in rewards, gameplay, and rules. You should always check for in-game bonuses, maximum rewards, and bets. Some casinos even have mega spins, where you have multiple reels that you spin simultaneously.

Which Type of a Slot Machine Is Better to Play?

The best online slot is the one you fully understand, enjoy and that fits your budget. If you feel nostalgic, you can try 3-reel spins with simplistic rules and frequent but small rewards. If you are a risk-taker, you should play 5 or more reel spins. And if you have patience and resources, you should try to land a big reward at progressive jackpot slots.

You should also remember that the bigger bet you make, the higher are the chances to win. And remember about keeping your bankroll under the limit because gambling is a means of entertainment only.

Strategy to Winning at Slots Online

There is no universal strategy to play slots because they have a random number generator that prevents players from finding the perfect strategy to win. Since slots work randomly and illogically, you cannot change or crack them in legal ways. Instead, you should follow the tips that will help you increase your odds of winning:

  • Take advantage of game bonuses
  • Set a limited bankroll
  • Find the highest RTP (return to player) percentage
  • Make an eligible or maximum bet (only if possible)
  • Observe the payout amount and frequency
  • Learn the rules

Following these tips, you will choose your slot machine wisely and bet the amount of money that you can afford.
