What makes a best online slots site?

When looking around for the best online slots apps, you should be aware of what makes or breaks a good deal. Knowing and spotting the good qualities of a site should save you the hassle of signing up for an account at a potentially rogue site.

Availability of Online Slot Games

You should always check that there is a diverse selection of games. The best online slots on offer should also cover various slot game types, such as classic, megaways, and video slots with in-game bonus rounds and different themes.

Cafe Casino does a good job of ensuring that players have access to the best online slot machines.

Casino Bonuses

The best online slots casinos offer various types of bonuses. Whether you are a new depositing player or a loyal one, you should be able to benefit from a wide range of bonuses, including a welcome bonus, reload bonuses, cashback deals, and free spins deals, among others.

While the size of the bonus matters, pay careful attention to the terms and conditions that come with bonuses. Wagering requirements, caps on winnings, game exemptions as well as game contributions are all essential terms that you must understand. Bear in mind that the lower the wagering requirements are, the higher your chances of meeting them.

Safety and Security

Signing up for an account at a licensed real-money online gambling site is only one step out of many in terms of keeping yourself protected online. Regulated casinos must adhere to various rules and laws as stipulated by their gambling authority.

This entails the adoption of SSL encryption technology as well as firewalls. If you want to be extra safe, opting for cryptocurrencies and e-wallets helps safeguard your bank card details at online casinos. 

Jackpot Games

Some jackpot games are local, which means the jackpot prizes are given away by the casino, while progressive jackpots encompass bets and jackpot prizes from a network of casinos. The difference is between the two can be huge, especially when it comes to the size of their prizes, which vary from a few thousand dollars (local progressive jackpot) to several million dollars (networked progressive jackpot).

Bovada Casino hosts Hot Drop Jackpots, with participating slot games coming with no less than three guaranteed jackpots. These can be won hourly, daily, or when a specific amount has been collected.

Variety of Game Providers

You want to have access to more than one software game developer, especially when it comes to the best online slots.

BetOnline is a great example of a top slots site that hosts numerous game providers. To date, it hosts the likes of Betsoft, Microgaming, and RealTime Gaming, among many others.  Having access to a good number of game providers gives you instant access to different types of slot games.

Mobile-friendly Slots Sites

Mobile-friendly slot sites are important because an increasing number of players are playing on the go and fewer on their desktop PCs. Some providers give players the option to download real money casino apps designed for iOS and Android mobile devices, but a large number of slots sites have created their websites using HTML5 technology. 

Mobile technology ensures that the website works on most mobile devices and operating systems as long as you are connected to the internet. The Wild Casino is one such example. It offers no mobile casino apps for download, but you can also access the site from any web browser.

The games adapt to the contours of your mobile devices’ screen sizes, while the buttons and the text have been enlarged for better legibility.

Types of video slots

It is important to understand the different types of online slots available on the market so you can better identify the best Vegas slots for your bankroll size and preferences.

Here are the major types of online slot games:

  • Classic Slots are also known as three-reel slots. They feature three reels and a handful of paylines.
  • Video Slots often come with five reels and usually have more features than three-reeled slots, including free spins bonus rounds, multipliers, and a higher number of paylines.  These games usually come with different themes, such as books as well as Egyptian and Norse mythology.
  • Progressive Jackpot Slots mean that a portion of the wager you make will go toward the jackpot prize. These games tend to have a lower return-to-player.
  • Six and Seven-Reel Slots are very similar to five-reeled slots, but they also pave the way for longer matches and unique structures as well as a higher number of paylines.
  • Virtual Reality (VR) Slots are still new, but they allow players to immerse themselves in a virtual environment that mimics the real gambling experience.

Features of Video Slots Online

One of the biggest benefits of modern online slot machines when compared to traditional slots is that they come jam-packed with extra features, which increases your chances of hitting a winning combination.

Below are some of the most common in-game features found in slot games. For more information on slot features, tips for winning, and how to play, refer to our online slots guide.

Wild Symbols

One of the most popular and widely used features in online slot machines is the wild symbol. The wild acts as a substitute and replaces other symbols in a bid to create a winning combination. Similar to the Joker card when playing cards, wilds will help create winning combinations. Wilds generally do not replace scatter or bonus symbols.

Expanding Wilds

Expanding wilds are similar to regular wilds except they expand to cover an entire reel. This can create many additional winning combinations.

Shifting Wilds

Shifting wilds are a different variation of regular wilds. They act similarly to sticky wilds. They will stay on the reels and move one spot to the left with each spin. If they land on the fifth reel, they will stay on there for 5 spins.

Stacked Wilds

Stacked wilds are similar to expanding wilds, but instead of covering an entire reel, they will come in stacks of 2, 3, 4, or 5 wilds.

Sticky Wilds

Sticky wilds stay put in their place for several spins. It may also act to replace any other wild symbol.

Scatter Symbols

Scatter symbols generally have one main role in a game, namely, to help earn you an entry into a special bonus round. This could be a Pick ‘n Win bonus feature or a free spins bonus round. You would need to land a specific number of scatter symbols on a single spin to trigger the bonus round.

Free Spins Bonus

Tying into our previous point, scatters can earn you an entry into the free spins bonus round provided you have landed the right number of scatters on a single spin. When you do, you will earn yourself a number of free spins. In some cases, you can also be awarded multipliers to go hand-in-hand with this bonus round.

Free Spins Retriggering

Retriggering occurs when you successfully land a number of symbols that would generally put you into the free spins bonus round. If this occurs in the midst of a free spins bonus round, you will receive extra free spins.

Cascading/Tumbling Reels

Cascading or tumbling reels are an interesting feature that is loved and appreciated by most people who play slots. Whenever you land a winning combination on the reels, all participating/winning symbols will blast off the reels, making room for new symbols to fall into their place. 

Essentially, cascading reels trigger a re-spin. They keep on going until there are no winning combinations left. In some slot games such as Gonzo’s Quest by NetEnt, there is an increasing multiplier attached to every tumble that occurs.


Volatility refers to the risk element of a game. A highly volatile online slot game pays out less frequently than a low-volatile slot game, but when it does, the wins are big. 

Volatility is as important as the payout percentage of a slot game, and you should be aware of it because a highly volatile slot game can steamroll over a small bankroll.

Bonus Games

Most video slots come with their special theme, but also their own special bonus games. These tend to vary from one slot game to another but could entail Pick ‘n Win, random chance, and wheel of fortune, among others.

Win Both Ways

Most standard online slot games only pay when identical symbols land from the leftmost side of the reels going to the right on a payline. With Win Both Ways, you can achieve wins on both left-to-right and right-to-left.

Gamble Feature

Some online slot games give you the gamble feature. This feature is quite popular in most classic slot games. It gives those who play slots online the opportunity to gamble their winnings by correctly predicting the color of a playing card or the suit. If you guess correctly, you double your winnings, but if you are wrong, you lose your winnings.

Multiplier Symbols

Multipliers are symbols that multiply your winnings. If there is a 2x multiplier forming part of a winning combination, you will receive twice the amount thanks to that specific multiplier symbol.

How do online video slots work?

Online video slots work a tad differently to land-based slot machines. Because slot games use software, they each come with a random number generator (RNG) that produces random and impartial results, so there no such thing as loose or hot slot games in the online gambling world. 

Instead, each spin of the reel is independent of the next one. RNGs at online casino sites are regularly checked and audited by independent third parties to ensure that they are working like they should and provide players with a fair gambling session.

How are online video slots audited?

Online casino sites would not be possible without the aid of RNGs. When it comes to the evaluation of RNGs, gambling operators leave this delicate process in the hands of third parties to ensure fairness. Operators as well as regulators also test the auditors who work with software game developers.

There are various agencies whose sole purpose is to test games and gambling software. eCOGRA is one of the most prominent auditors in the gambling world.

A casino site that has an eCOGRA seal of approval is considered to be of the highest quality. Auditors test the RNGs to ensure that they are intact. Because RNGs use a seed to produce a string of numbers and determine the result, they need to be checked on a regular basis, and because the strings of numbers do not follow any specific pattern, they are unhackable and unpredictable.

If a casino does not have any seals or evidence that its games are being checked and audited, you cannot trust that the casino will not find a way to rig a game. It is important that along with evidence of a valid gambling license, you also look for the logo of an independent auditor.

Which bonuses and promotions are available to online slots players?

There are many types of bonuses and promotions available on the market. The best online casino bonuses include:

No Deposit Bonus

A no deposit bonus is one of the most lucrative deals available in the online gambling market. It is essentially a freebie given away by online casinos in a bid to attract gamblers to sign up and play online slots.

A no deposit bonus can either entail a number of free spins on a specific slot game or a lump sum of bonus cash for players to spend on qualifying games. There is no catch. All players have to do is register for their account and the bonus will be credited to their account. You do not have to deposit to claim it.

While this type of bonus will come with terms and conditions and higher wagering requirements, it allows you to play games of a wider range and gives you the chance to play games you love as well as new games without putting your funds on the line. If you are claiming no deposit free spins, the number of spins may be smaller when compared to free spins given away against a deposit.

Welcome Casino Bonus

A welcome bonus comes as part and parcel of all online slots sites. It is given away to all new sign-ups who deposit for the first time. A welcome bonus can come either in the shape of a match deposit bonus, a number of free spins, or a mix of the two.

A match deposit bonus is by far the most widely available option. The casino matches the money deposited by a percentage. For example, if you are claiming a 100% match deposit bonus up to $100 and you make a deposit of $100, you will have a total of $200 with which to play slots.

Match deposit bonuses come with their own set of advantages and very few disadvantages. When compared to free spins bonuses, they give you more freedom to use your funds on the best online slots with very few restrictions. The one downside is that game exemptions usually apply.

Most casinos exempt high RTP slot game wagers from contributing towards the wagering requirements. It is of utmost importance that you read the terms and conditions of any casino bonus you are claiming to avoid placing bets on slot games that do not contribute towards the playthroughs.

Free Spins Bonuses

A free spins bonus is exactly what it says. You receive a number of free spins to spend on slots games. In the majority of cases, the casino decides which slots you are allowed to play your free spins on.

However, you may want to tread a little carefully with free spins bonuses. While they are great for slot fans, most casinos usually pick low RTP slot games. You should also watch out for the value of the spins as they may be of a lower value and therefore not generate big wins.

Free spins bonuses do not bring that many advantages when compared to match deposit bonuses because you are constrained when it comes to the games and the bet size value.

VIP Bonuses

Regular players have the chance to join exclusive VIP programs where they will benefit from a wide range of perks and rewards. Besides higher and faster withdrawal limits and a personal account manager at your beck and call as well as 24/7 VIP customer support, you can also benefit from tailor-made bonuses that are not available to other players.

VIP bonuses tend to come with lower wagering requirements although these will likely vary from one online casino to another. They are highly beneficial for VIPs, but generally, in order to join a VIP program, you would need to make large deposits over a period of time. VIP bonuses are better suited to high rollers than low rollers.

Cashback Bonuses

Cashback bonuses are widely available at offshore online gambling sites. They offer players a percentage of their net losses back. They may or may not come with wagering requirements attached. 

Their main benefit is that even though you have lost the money deposited, you still manage to recoup some that can be used to extend your gambling session.

The main downside of cashback bonuses is that percentages are usually on the lower side. With most online casinos, the percentage will vary depending on how much you have deposited. Cashback bonuses can start from as low as 5%.

Online video slots vs land-based slots

You will be surprised to learn that online slot games come with a wide range of benefits that outweigh those of their land-based counterparts. These include:

  • Convenience factor: You don’t have to drive into town to play slots. Online video slots are available at the click of a button on your phone or desktop PC.
  • A bigger quantity of games: You can expect to find hundreds, if not thousands, of the best online slots. There is no space issue.
  • Higher payout percentages: Online slot machines boast a higher RTP than their land-based counterparts. You can also easily find out what the RTP of an online video slot is.
  • Play for free: You can try online slots for free without risking any of your own funds. Playing free slots with no download, allows you to get a good idea of the volatility levels, suss out the in-game features, and check if the game is to your liking when you start playing online slots.
  • 24/7 availability: You can access an online slot machine at any time of the day or night. There are no restrictions and online casinos never close.
  • Payment methods: Most online casinos accept a wider range of payment methods, including e-wallet options as well as cryptocurrencies. All deposits and withdrawals are processed in a safe manner and protected with SSL encryption technology and firewalls.

What are Free Video Slots?

Free online video slots provide you with virtual money to play. Free slots are games played in demo mode. While you will achieve wins, the cash won is not cashable.

The main purpose of free slots is for players to test out a new slot game, see if it is to their liking, and sharpen their strategy before playing slots for real money. However, the best free slots are just as thrilling as their real-money counterparts, with incredible graphics, exciting themes, and loads of fun.

What are Real Money Video Slot Games?

Real money slot games are games played with real money. Players can place different wager amounts on any slot game of their liking. When they hit a win, the winnings are real money.

We would like to note that if you are claiming a casino bonus, any money generated from the slot game is bonus cash and not real money. You would need to meet the wagering requirements and any other terms stipulated by the casino before the bonus cash can be converted into real money.

Deposit and withdrawal methods at video slots casinos

Most offshore online gambling sites accept a wide range of payment methods that cover all types. These include:

Debit and Credit Cards

These, to date, are the most popular type of payment method among players at online casinos. All online casino sites accept credit cards like Visa, Maestro and Mastercard.

Debit and credit cards are both viable options for making deposits and withdrawals, thanks to their high-security features. Withdrawals can be a little slower, but when it comes to top-notch security and fast deposits, they do a highly exceptional job.


E-Wallets have gained increasing popularity in recent years. These are extremely secure payment methods and are exceptionally quick for making deposits and withdrawals.

They are a smidge safer than debit and credit cards since all your card details are provided to the e-wallet rather than online casino site.

While some fees may apply, they tend to be low. You have the option to shop around for some top deals, with some e-wallets offering more competitive fees. Neteller, for example, also has a lucrative VIP scheme enabling players to access various perks the more they use the e-wallet.

Other popular e-wallets include PayPal, ecoPayz, and Skrill.

Keep in mind that most offshore casinos do not accept e-wallet payments from US-based gamblers. To pay by PayPal or Skrill, you’ll need to use MatchPay as a proxy peer-to-peer payment gateway or use your e-wallet funds to buy cryptocurrency or a prepaid voucher and deposit with that.

Prepaid Vouchers

Prepaid vouchers provide players with a high level of convenience, especially if they are skeptical about using their bank cards online. Prepaid vouchers such as PayNearMe and PaySafeCard allow users to exchange cash at hundreds of local stores for a voucher. These vouchers can be applied during the depositing process at an online casino.

Since you are not exchanging details, it is also a highly secure payment method. It cannot be used for cashing out your winnings, however. To cash out, you will have to opt for an alternative method.


Cryptocurrencies are on the rise with players now having the option to make quick deposits and withdrawals via their favorite cryptocurrency. Cryptocurrencies such as Bitcoin, Ethereum, and Litecoin are some of the most popular methods available for deposits and withdrawals at online slot casinos.

Not only can you benefit from instantaneous transactions, anonymity, and security, but because cryptocurrencies are decentralized, they are not routed via a central authority, such as the government.

All transactions are carried out from one person to another, without the involvement of a third party. Deposits and withdrawals are also far quicker. While some minor transaction fees apply, the fees are considerably lower than those of conventional fiat currencies.

Pay by Phone

A Pay by Phone payment method enables you to make deposits by entering your mobile number. While it cannot be used for withdrawals, it is a quick and convenient way to make a deposit.

Bank Transfers

Bank transfers are old-school, but still highly effective. Whether you want to opt for a wire transfer or eChecks, many online casinos like Cafe Casino and BetOnline, allow players to make deposits and withdrawals via this payment method.

Bank transfers are notoriously slow, and some online casinos apply fees on deposits and withdrawals. They also tend to have a higher minimum threshold than other payment methods.
