Real Money Slots vs. Free Money Slots

Most real money online casinos offer both real money betting and free money games. Read on to learn about the pros and cons of each.

Real Money Slots

One of the key benefits of playing online slots for real money is game variety. You will be able to access every game across all casino sites that you bet at, with no restrictions.

Playing for real money also unlocks a huge range of unique bonuses. You will be eligible for gifts including free spins, tiered loyalty rewards, real money prizes, and much more. You will also have the chance of winning large jackpots. This alone will add an element of anticipation and excitement to the overall experience.

Remember, although you have the potential to win real cash, payouts may not be instant. Some banking methods may take 3 to 5 working days to release the funds into your bank account.

It is also important to remember that with real money betting, you should set aside a budget and stick to it. One of the pitfalls to playing slots for real money is that you cannot win every bet you place, so you should only bet what you are comfortable losing.

Free Money Slots

The main advantage of playing like this is that you can try out several several of the best free slots without risking your money. Immerse yourself in the experience and enjoy slot games without spending a cent.

This is great for new and inexperienced players, as it provides the opportunity for practicing and learning the game. You can enjoy the features and dynamics of the game without the worry of losing. If you are an experienced player, free slots will allow you to test out your betting strategies before placing real money bets. Having said that, you will have limited access to the number of slot titles you can play for free.

Playing free slots also means that you’ll miss out on jackpots. On the flip side, your anonymity is guaranteed because you’re not required to provide personal or payment information to play in demo mode.

How We Ranked Online Slots Casino Sites

With so many great online casinos, how do you know which one (or two or three) to choose? Are the bonuses fair? Are the online slots rigged?

We dig deep into every online slots casino that we review to find you the best games and promotions. Here’s a quick summary of the criteria we look for when hunting out great slots casinos.

Casino Bonuses

Bonuses are a very important aspect of online casino sites. For new players, it can often be the deciding factor. For example, Red Dog Casino has a great welcome bonus for real-money and crypto deposits plus additional bonuses for existing customers.

The first bonus we consider is the welcome bonus of each online casino, taking a close look at the match percentage and the rollover requirements. We also look for any additional bonuses available including loyalty programs, refer-a-friend programs, and daily bonuses.

Number of Slot Games

Most players will have a favorite slots game but you wouldn’t go to a casino to play just the one game. With that in mind, having a wide variety of slot games to choose from is paramount.

For this reason, we always consider the number of slot games our top-rated casino sites have available. There should be a good mix of styles, themes and bonus features across all games.

Software Providers

Another aspect of our reviewing process is considering the software providers that our ranking casino sites use. Some online casinos will work in collaboration with just one or two game developers, while other casino sites will work with several providers.

For example, Cafe Casino work with seven providers. Every software company has its own specialty, graphics, and features to offer, so this is important when reviewing the quality of the slot games.

Payment Methods

It’s important that the casino site supportsyour preferred payment method. You may want the speed and security of a debit card or the anonymity of a Bitcoin transfer. We always check every casino site to see what their available payment options are.

In addition, we always check minimum and maximum deposit limits as well as withdrawal processing times. Wild Casino, for example, is one of the our top-rated online casino sites for easy-to-use payments and speedy, fee-free withdrawals.

Customer Service

Customer service is crucial for real-money casino players. We check whether casinos offer 24/7 live chat and email support, as well as an FAQ section for go-to help.


The safety and security of all players is vital and perhaps the most important aspect to consider. We only recommend online casinos that are regulated to ensure the fairness of games and that players are protected at all times while playing.

Types of Online Slots Bonuses

Casinos regularly update the bonuses on offer, so we recommend always checking in with your chosen casino sites for their up-to-date offers.

As two casino sites rarely offer the same bonus, there is always plenty to choose from. With this in mind, here are some explanations of the most popular slots bonuses available.

Welcome Bonus

A welcome bonus is a slots bonus for new players when they set up their account for the first time. The welcome bonus may include a mix of free spins plus a deposit match offer.

To claim your welcome bonus, simply open a new account and make your first deposit by card, crypto or bank transfer. You may also need a bonus code when you opt in.

You unlock welcome bonus funds by clearing your matched bonus funds according to the wagering requirements. Always check the terms and conditions before you claim your casino promotion.

Free Spins Bonuses

You can also claim a free spins bonus when you join up. Some online casino sites also offer free spins to regular customers.

Free spins let you play online slots with zero risk. You can unlock your free spins winnings as long as you meet the strict rollover terms and conditions.

Deposit Bonus

Deposit bonuses are another popular promotion offered by slots casinos. The casino matches your reload by 25-50% on average. You can clear your bonus funds by playing eligible casino games and slots.

No-Deposit Bonus

With a no-deposit bonus, the online casino will give you a bonus amount for simply creating an account. As the name suggests, there is no deposit required to receive this bonus offer. However, you may need to meet the playthrough terms before unlocking any winnings.

Exclusive Offers

Most online casinos offer exclusive promotions to their customers. Exclusive deals usually cover a new slot release and may include free spins or other bonuses. Some online casinos also offer slots tournaments guaranteeing cash payouts, gadgets and other prizes.

Reload Slots Bonuses

A reload bonus is great if you like playing casino games regularly and earning free cash. The gambling site offers you a small deposit match bonus that’s similar to a bigger welcome bonus. Use your bonus funds at the best online casinos to play eligible slots or classic table games.
