Play Responsibly in Slot Games For Fun

Before gambling for real money, remember always to play responsibly, as gambling is risky and addictive. Be cautious when spinning the reels in slot games at online casinos when you bet real money. We advise you to read more about responsible gaming at the independent charity BeGambleAware® before you bet your money on online casinos.
BETO™ & BeGambleAware® share the mutual mission of keeping you safe from gambling harm.

BETO wants you to play responsibly. Below are our official guidelines to ensure you never end up in an unhealthy situation:

TIP: Set a fixed budget for your gaming session. No matter what slot you play, you should always set a predetermined budget (bankroll). This limit is a fixed amount of money that you are willing to and can afford to lose when you start your playing session on video slots.

Keep track of your spending when playing slot games for real money. Like all other expenses in your life, you should always keep track of how much money you are spending when playing real money slots at online casinos. There are several ways to do this: Use an app for your budgets, a simple spreadsheet on your computer or just a piece of paper. Make sure you note down the details of your gaming expenses.

Bankroll is a free tool you can use to play responsibly.

Bankroll is a free tool you can use to play responsibly.

Betting on free slots for real money requires self-discipline

Keep track of time: it is easy to lose track of time while playing slots online.
Set a clock when your gaming session starts. This is the only way not to lose track of time and not get too carried away in the entertainment.

Remember, playing on free slots here at BETO is just as entertaining, and you do not always need to play for real money. So, play free slots, and enjoy risk-free fun.

IMPORTANT: Never chase the next win to win back what you lost! This is a piece of important advice for all online slot players. If you have lost, don't try to win back what you lost by betting even more. Once your set budget is spent for the day, immediately stop playing.

Set a bankroll when playing online casino slots

Bankroll and Budget: Your bankroll size should be set, so you do not regret losing the money you are gambling. If you feel troubled by the lost amount, you should stop playing and walk away from the screen to calm down your body.

Playing slots online should always be a fun experience, and you must stop playing if the spinning sessions turn into a bad experience.

What are free slots? A free slot is an identical demo version of the real money slots found in online casinos. In these demo slots, you play with "fun money". This means that you will never lose real money as your casino chips for the games are free coins and tokens with no real value.

Here at BETO™, you get access to all the fun, free las vegas slot machines, and it is the perfect way for you to become a better player while learning different tips, tricks, and strategies that our experts share each week.


Considerations when Playing Free Online Slot Games

At BETO, our gaming experts recommend playing between 150 and 200 spins on free casino slot games before deciding whether you want to spend real money on a game.

This trial run on free online slots gives you the no-cost opportunity of an authentic feel for the game, whether it is a super slot machine with powerful Boosters or a classic video slot without any kind of sticky wilds or scatter symbols.

When you play free slots, pay attention to:

  • Graphics and slot themes. If you like potent graphics and sound effects, try free online slot games that offer you such a visual feast.
    If you're bored by the theme of a particular slot, it is not worth spending your real money on, and you should try some additional slots instead.

  • The bet sizes. Betting ranges offered in the best free slots games vary. This range should always be of specific consideration when playing free slot games. If the minimum bet is too high for you, then it is not wise to play for real money.

  • Odds and your chances of winning. Reviews of online slots here at give you essential information regarding RTP (Return To Player %) and volatility. You as a player do not always know how fast a game depletes your bankroll before you start your spinning session, so educate yourself in advance through BETO's free slots and reviews.

  • Free spins and slot bonuses. You can play for what may seem like an eternity before triggering a bonus game and in-game spins for free. Figure out if this is the case while playing free slot machine games, as you'll get a good feel for a game during your 150-200 free trial spins.

You can not be a lucky player every time!

You should know how long it can take to hit a bonus game when playing on free slots. This duration is directly correlated with the variance of the particular free slot combined with luck. Before risking real money, always ensure you are okay with the time it takes or if you think it takes too long to hit the big wins.

What are Free Spins and Bonus Rounds?

A Free Spin bonus is free rounds on your favourite slot machines, which you can enjoy without risking your real money on slot games. You can still win real money on these free spins, but you can not lose anything - this makes them the perfect promotional offer for most players. These bonus offers are recommended if you are a beginner or a professional online casino player.

If you play progressive jackpot games, these free spins also let you win some big prizes and gigantic jackpots. Even though these spins do not cost you any money, you can still win some big wins on them.

A Free Spin bonus game is also a feature available inside most modern slot games, and this dual meaning is confusing to new players. In this section, we refer to the promotional meaning of the phrase.

Free Spins on real video slots

BETO lets you experience progressive jackpot slots for free to see whether they excite you enough to consider investing your hard-earned money. Playing free jackpot slots in a safe environment is an excellent way to get a feel for this specific kind of game.

We have the most significant progressive online slots where you can try your luck at winning the big jackpots, including top online casino games from the famous Mega Moolah series.

If you are not familiar with how progressive video slots work, then here is a quick review of how these increasing jackpots excite up your gameplay:

  • A progressive jackpot slot starts with a minimum balance. It can be anywhere from 1000 to over a million.

  • Each time players bet on the game, they contribute a small portion to the growing jackpot size. This jackpot grows into a massive balance of several million.
    As the un-triggered progressive jackpot grows, the incentive to play on the particular slot increases, and it will cause an even larger balance as more players try to trigger this life-changing jackpot.

  • Once the jackpot is won, the game resets its starting payout amount. Then the process starts all over again.

Choose Games that Suit Your Personality

If you have spent time with people who love playing slots for fun, then you have probably noticed how they trust their intuition and senses when choosing which slots games to play.

An expression like "The game is hot" or "avoid this online slot machine" and "it's cold" are phrases you often hear from such players, but let's kill this myth right now - Slots are neither cold nor hot!

Instead, these games have different features, mathematical limitations, and odds. Although it might feel like you are constantly losing or winning on free casino slots games online, it is a matter of luck and coincidence.

Below you'll find BETO's fact-based guide to choosing the most suitable vegas slots games. You'll learn which slot games are best for your wallet and which are best avoided if you want less risk and win real money.

Since BETO bases this guide on hard facts, we had to gather a lot of data, some of this data is public, but not all, so the combined data are what we believe - The ultimate resource for new and advanced slot players.


RTP% - Return To Player Percentage

The return to player percentage, or just RTP%, is a percentage-based measure of how much of all money spent on a video slot will be paid out to you in the form of winnings.

An easy way to understand RTP as a beginner is that it shows how much you will be left with after a long period of playing. Generally, RTP in free slot machines is around 90 to 95 per cent. The 0-10% part is the house advantage. In short, this is the sum that the casino retains over time.

Many developers of video slots publish this information as part of the fact sheets for the games, and so do some of the real land-based casinos. To sum up, a slot game with a high RTP (over 95%) will return more of your money over time compared to a lower RTP slot machine.

It gives the house advantage if you want to play slot machines

An online or land-based slot machine receives money from players for each spin/round on the machine and returns a predetermined percentage in the form of winnings, also called the return to player rate.

The remaining sum is the house's advantage and is retained by the casino. A casino's house advantage is also called its ownership interest or house-edge.

For example, a video game machine with an RTP of 93.5% has a house advantage of 6.5%. Online slots with an RTP of 96.75% have a casino keep rate of 3.25%

The Effect of Variance

Slot machine variance, or volatility, is the probability of triggering a winning combination.

High variance: You'll rarely trigger a winning combination on free slot machines online with high variance, but highly volatile free slots offer much larger payouts when you finally trigger the win. It requires a larger budget when playing on video slots with a high degree of variance.

Low variance: Conversely, a slot with low variance gives frequent wins, but as a result, the payouts are a lot smaller.

Medium variance: These play free casino games are an excellent middle ground between the high and low variants. And will give you a balanced gaming experience. The volatility of video slots is essential before choosing which best free slot games to try. It's important to choose carefully before selecting a title worthy of real money games.

You'll experience the effect of variance when you play the free slots here at BETO.


Different Themes in Free Slots Games

When deciding which free slot machine games to choose, not only hard facts should be part of the decision-making. A game's theme is also an important part. From seasonal play free slots online to classic mechanical one-armed bandits, there are hundreds of themes available for you that are available across many online casinos.

The theme of the video slots is the most subjective part, as different people love playing no download free slots with different game themes. We are big fans of the prominent Hollywood franchises with superheroes and Vikings, and they also have their own branded free slot themes.

There are no objective guidelines for selecting a casino games theme, and it's solely about what you enjoy and which free games give you that unique visual entertainment you search for.
