Why Would you Want to Play Slots Online?

Firstly, a lot of people play slots online because they physically can’t get to a casino. Maybe there aren’t any in the area, or it might be illegal to gamble where they are.

Even if you do have a bunch of casinos near you, there are still tons of reasons why online casinos are a better option mainly for freedom. There is so much freedom when playing online video slots. You can play a slot on your computer at home at any hour of the night or day. Or, for an even better sense of freedom, you can play a slot on your mobile, anywhere, anytime.

Of course, we don’t play online slots just for fun, though, you could be in for a serious payday if you play your cards right. As opposed to physical casinos, some online slots offer progressive jackpots so that private island retreats in the Maldives could be closer than you think.

What Features do Online Slots Casinos Offer?

With online casinos dedicated to slot games comes a bunch of features that you wouldn’t usually find at any other casino. These are super cool ways to entice you to play and could even end up winning you some cash. Let’s take a look at some of their main features and what makes them truly unique in terms of entertainment.

Free Spins

One-way slot sites try and entice you to play with them is by offering free spins. Sometimes these spins can be used on any slot game, but other times they restrict it to select games only. There are two types of free spins; deposit and no deposit.

Of course, it is nice when you stumble across no deposit free spins because then you’re not risking any of your money and you don’t have to stay playing on that site if you don’t enjoy it after. However, if you do win money with no deposit free spins, most online casinos make it tricky for you to withdraw your winnings no strings attached. You’ll usually have to deposit to get it back.

Sometimes online slot games will offer you free spins when you make your first deposit. In these cases, they usually offer more free spins than for no deposit ones. Sometimes they can offer anything up to 300 free spins as opposed to maybe about 20 without a deposit.

Loyalty Bonuses

Now here is where being a loyal customer comes in handy. Casinos don’t advertise these bonuses on their websites, but if you’re a loyal player at one online casino, you’ll likely get the VIP treatment at some point.

Loyalty bonuses usually involve getting cash back or tiered bonuses, while some also offer Birthday and Christmas bonuses to existing customers too.

Slot Stats

When it comes to online slots, the casino will give you some stats to look at. The most important one of these is the RTP which stands for Return To Player. This percentage is the average amount that is returned to a player for that slot, so you’ll want to look for the highest percentage you can.

Anything higher than 96% or 97% is an excellent place to start. This is another reason why online slots are so popular; if you were in a physical casino, the RTP would be more like 92-95%.

Remember those progressive jackpots we mentioned earlier? Well, this is the only time you’ll get an RTP of over 100%, but be sure to place the maximum bet you’re allowed. This is usually the rule for being eligible for the progressive jackpot. A progressive jackpot slot will be clearly indicated on the casino you are playing so keep an eye out for the progressive slots for a possibly bigger win potential.

If you’re interested you can look up the yearly stats for a slot game you like. It’ll tell you how many times it was played, the biggest win for the year, the hit rate and the average bonus win.

Mobile Slots

Mobile slot play is perhaps the greatest technological invention of the century, our mobile phones can do almost anything, and that includes playing slot games on the go! Most online casinos have adapted their slot games and sites to work seamlessly on your mobile device.

What Types of Online Slots are There?

Quick Answer: There are three main types of online slot games; classic, video and jackpot.

Classic slot games are the most similar to the real slots you find in casinos. They usually have three reels and one or more pay lines. They’re simple, and usually, the bets are relatively low, so this makes them suitable for beginners. The reels will usually have symbols of fruits, bars, bells or lucky 7’s. There are not typically many bonus features with this type of slot except a wild symbol or two, so the gameplay is rather simplistic. Popular games under the classic slot genre are Beetle Frenzy, Starburst and Pirates Gold.

Video slots will always contain more reels than classic counterparts. They can have five or more, and more importantly, they will have more pay lines too. Sometimes video slots have been known to have up to 1,024 paylines! Popular games come from the likes of Play’n Go and include great titles such as Fire Joker, Eye of Horus and Gonzo’s Gold.

Jackpot slots (or progressive jackpot slots) are where the real fun is at. In these, the jackpot increases each time you make a bet and thus these games have an above-average RTP. It keeps increasing until it is won and then it returns to the standard winnings. These jackpots can get up to millions of dollars!

There is also divination within these three groups as to how the payouts work for example in more traditional video slots like Bier Haus and Rainbow Riches the payout system is how you would expect it to be, but in games like Aloha Cluster Pays, the slot pays out in a different manner. There are also Megaways slots that increase the number of paylines in a game to astronomical levels and these slots are some of the most popular on the market at the moment.

Different developers make slots, and this can be a good thing to look out for to make sure you’re playing with reputable makers. Some renowned game makers include NetEnt Betsoft, Elk Microgaming Endorphina, Play’n Go, Push Gaming, Blueprint Gaming.

When it comes to online slot games there is a little something for everybody from experienced players to slot novices. Most find playing online slots a thrilling experience as there are generous bonuses, lots of special features and new games released every week. Players also love the wide variety of slot games that are available at online slot sites.

Of course, gambling is a serious matter and can quickly become a problem if you let it. Most casino sites have online support for your gambling if this is the case, or you can take a look here for more information on responsible gambling. Online slots are not intended for this; they are fun, exciting ways to play and possibly make a bit of money too.

FAQ

How are Online Slots Different from Playing in a Real Life Casino?

Playing slots online is similar to playing in a land-based casino, but there are a few distinctions. One is that online slots have an RTP of 95-97 per cent, but land-based machines have RTPs as little as 75 per cent. Another is that you are able to play from the comfort of your own home so online slots can be more convenient for those with busy lives!

Can you Play Slot Machines on your Phone?

Yes! Most mobile devices are now compatible with many online casinos. You can normally play slots from your mobile device, whether it’s a phone or a tablet. Because of the huge popularity of these games online, mobile casinos have prioritised slots. Individual games are loaded using the phone’s browser after a simple login at the mobile site. In most cases, you’ll only need your desktop account’s login information. Because many online slot machines use similar coding, you won’t have any trouble loading them on your iPhone, iPad, or Android tablet. Take a look at our slot reviews to see if your favourite slot is compatible.

Can you Win Real Money from Online Slot Games?

If you find the right game to play then yes! Another approach to profit from online casino slots is to take advantage of bonuses. To encourage more customers, online casino companies frequently provide free money, a free spin, or a free game. These are usually the normal bonuses that you might get while playing slots and other well-known games. To make more money on these games, you must be clever and responsible about the amount you wager. Set reasonable expectations and bet wisely if at all possible when playing. Also, always read the bonus’s terms and conditions. You may choose to play online in order to earn real money, but you should be aware that this is a difficult goal to achieve every time; instead, it should be about having fun!

How do I know if an Online Slots Casino is Reputable?

Do your research and make sure they’re licenced! You can tell if an online casino is legitimate or not by looking at the reviews and comments area. You may learn about the services offered as well as other information that will assist you in determining whether or not the online casino is legitimate. You should be aware that fake online casinos do not provide slot games, which may help you categorise them. You’ll notice that the vast majority of rogue internet casinos don’t put their money into online slots. The reason for this is that their primary purpose is to defraud players of their money. At CasinoRange, all of our slot and casino reviews have been double-checked to ensure that they are secure and reliable platforms.

Can I play Online Slots for Free?

Yes, you certainly can. There are countless ways of playing the game in demo mode for free. However, you can no longer play for free in the UK without passing age verification checks. If you’re of legal age, free slots are a fantastic place to start if you’re new to slot machines or casino games. This will allow you to get to know an online slot machine from the inside out, with no limits on how much time you can spend doing it.
