Some casinos focus almost exclusively on one provider’s games, while others boast diverse platforms packed with different types of games. Another thing to consider when choosing between the numerous online casinos offering demo versions is how generous the bonus conditions are.

The welcome offer is especially attractive if the bonus can be activated in the free online slots and you can use the extra credits to test out plenty of exciting titles. Of course, it’s essential to remember that free credit obtained with a bonus cannot be withdrawn, but only used to play games.

Another factor you might want to consider is whether the operator’s platform is mobile-friendly. Lots of online casinos nowadays offer apps, allowing players to easily access their favourite games from their smartphones or tablet PCs, no matter where they are. And since most players nowadays own a mobile device, this option can be quite handy.

There are several factors which we use to rank the . First of all, we pay close attention to safety, making sure that the operators hold active licences by reputable regulatory institutions such as the United Kingdom Gambling Commission and Malta Gambling Commission.

Furthermore, we analyse the welcome bonuses offered by each casino. Ideally, the package should include free credits which can be used to play free online slots with a significant number of free spins too. Besides these two major criteria, we also evaluate other important aspects, such as the range of software providers, the quality of customer support, payment methods, mobile compatibility and more.

How Do Free Slots Work?

If you have already played at online casinos, then you are surely familiar with demo modes, as most games can be tested in a “fun mode”. If that is not the case, we will explain how that works. When you select an online slot, you usually have two options – to play for real money, or to open the game in demo mode.

If you opt for the second option, you will see a window popping up, asking you how much you would like to bet, and how many paylines you would like to activate. This is only for show, because the slot is actually played with virtual credits. The values that you select will be the same as if you were betting real money, meaning that if you hit a winning combination, the slot will light up as if you had really won something.

However, when you click the “Collect” button, instead of seeing actual money, a message will appear, informing you how many credits you have won. Another difference is that in demo mode, the spin does not consume all of the credits that you have selected as value. For example, if you select 1 pound per spin, and you have 1000 credits, a single game round will cost you one credit.

Free online slot machines allow you to set the automated spin function, just as you would do with real money. Another feature that you can test when playing in fun mode is the bonus rounds. These are usually triggered when you get three or more Scatter symbols anywhere across the reels. Sometimes, you need to make a higher bet in order to qualify for the jackpot – this information is usually displayed on the slot’s payscale. However, even when playing in demo mode, you will be able to hit the big prize.

Are Free Online Slot Machines Safe to Play at?

As we mentioned earlier, online casinos offer demo versions as a way to promote certain games. Each year, thousands of new slots are released onto the market, so software developers need efficient ways to advertise their products. Making demo versions available is a win-win situation – players can enjoy their favourite games for free, whilst software providers benefit from increased popularity.

Likewise, online casinos often feature demos of the games available on their platforms. So, yes, they are completely safe to play. In fact, even when playing for real money, you are taking no risk, if the operator is licensed by the UKGC. This regulatory institution closely supervises its partners, and requires them to operate according to strict rules, aimed at protecting players.

Among the many requirements, licensees must implement technical security measures to ensure the integrity of the random generation software. In simple words, this means that neither the operator, nor any other third party can influence the result of a game, and each outcome is truly random. Additionally, all games undergo rigorous testing to verify that the reported return to player rates are accurate.

Furthermore, safe online casinos protect the confidentiality of their customers’. Sensitive information such as names, addresses, phone numbers and banking details are stored securely on encrypted servers. All in all, as long as you stick to playing at licensed online operators, you don’t have to worry about the safety of your funds or personal data.

Play Free Online Slots for Tournament Practice

Slots tournaments are a relatively new innovation in the world of online gaming. Available at many reputable online casinos, they are an excellent opportunity for players to have some serious fun whilst competing against other gamblers for the chance to share a juicy prize pool. Usually, these events last for a few hours, during which participants have to play selected slot games.

Your score in the tournament depends on your level of activation, the number of spins and your win-to-spin ratio.** Some casinos also take into account the size of bet per spin. At the end of the competition, the top three players split the prize pool equally.

Participating in tournaments is an excellent way to add some extra excitement to your regular gaming sessions. What’s more, entry is usually free or very low cost, so it is suitable for both novices and experienced players who are keen to practise playing free online slots rtp. In fact, checking the RTP rate of each slot is a good tip for finding the best games around.

Another advantage of tournaments is that they allow you to try out new games or titles which you may have disregarded previously. Sometimes, you may discover a new favourite game. Tournaments are available for both real money and free online slots. If you are playing for real money, any wins will go directly into your account, and you can withdraw them afterwards.

How to Play Free Slots with Bonus Rounds?

Many online video slots come equipped with bonus rounds, giving players access to additional features. Different titles offer varying types of mini-games. Some of the most popular features include free spins, expanding Wild symbols, pick and click games or wheel of fortune style bonuses. To trigger a bonus round, you typically need to land three or more Scatter symbols anywhere on the reels.

These are special symbols which can unlock a variety of interesting functions. Of course, different games have their own unique rules, so it’s a good idea to check out the payscale beforehand. Fortunately, you can do that anytime – most slots allow you to open a window with the payscale where you can read all of the rules and winning combinations.

If you are playing in fun mode, keep in mind that when you hit a bonus round, nothing will happen. You will see the corresponding messages, but when you press “collect”, no credits will be added to your balance. This is just a demonstration of what happens when you hit the combo. If you have played in a casino before, you probably know that even hitting a bonus round does not guarantee you major winnings.

In fact, the most lucrative prizes are hidden in the regular symbols and their combinations. Still, bonus rounds are a nice touch, adding variety to the gameplay and breaking the monotony of regular spins. If you are interested in learning more about this topic, we have prepared a dedicated guide on , explaining how they work and listing some of the most popular titles currently available.

And while this can be a disadvantage, the fact that they can be used for free slot casino real money games is also an advantage, as any winnings will be instantly credited to your balance. As you can imagine, non-deposit free spins do not have a high maximum bet. This is stipulated by the UKGC, in order to prevent players from using the bonus to win huge amounts of cash.

Even though the bet limit may seem too small for some players, the fact is that this is a good way to test a particular slot and perhaps hit the jackpot. Many slots offer impressive payouts, so with a bit of luck, you could collect a hefty sum.

One such title is Mega Moolah, otherwise known as the “Millionaire Maker”. This African safari-themed game regularly awards multimillion euro jackpots. In fact, guinnessworldrecords.com lists the highest cash reward won from 1 cent. A lucky player scored a record-breaking €17,879,644 on Jeanne d’Arc slot. Like these games, Mega Moulah is a progressive jackpot slot, which means that its top prize is not fixed, but rather comprises a portion of the total sum accumulated from bets made across all online casinos featuring the game.

Another example is , which has yielded over 80 millionaires since its introduction in 2013. Needless to say, both games are very popular among players from the UK. If you are curious to learn more about progressive slots, feel free to check out our selection of the for British players.

Even so, playing at the lowest possible bet can still be exciting, as you can hit decent payouts with frequent spins.
