How to Choose the Right Slots Sites

When you have to choose among thousands of title, it becomes hard to pick the right slot for you. Slots are divided into classic 3-reels and 5-reel video slots. The 5-reel games come in a huge variety of themes. That is why browsing by theme is the easiest way to find your game. No matter if you are a nature lover, a fan of a popular TV-show or you like mysteries, just pick a slot dedicated to the theme you are passionate about. Some of the best slot machines to play are inspired by Ancient Egypt; other take you on an exciting journey through the jungle.

For example one of the most popular slot machines online is Cleopatra, which is inspired by the beautiful Egyptian ruler, who has some treasures in store for some lucky players. Another example is Zeus, which takes place in ancient Greece. Rainbow Riches is a well-known slot game which celebrates the Celtic culture. The high-quality graphics and lucky charms will help you hit that jackpot. Siberian Storm will take you to the wild Siberian tundra, where you can enjoy the magnificent snow tigers. The most popular games usually have sequels, so look out for them.

What is RTP?

You have probably heard this term already. It is the ‘return to player rate.’ It is often written in percentages and means the amount of money you will earn back for every dollar, pound or euro you wager. For example, if the RTP is 70%, then you will get 70 cents for every pound, euro or dollar. Online casinos do not usually publish their figures, but you can learn all about the RTP for all your favorite online slot games and sites on review and comparison websites. Experienced players are seeking for an RTP of 95% or higher. Another term you will often read and hear about when playing at slot sites is the volatility or variance. This concept is related to how often slot sites pay out and how much. If the volatility is low, that means the games are less risky and pay lower amounts. In the opposite case, high volatility means higher risk, less frequent payments, but much higher amounts.

Online Slots

If you want to feel the thrill of Vegas and play for free, you are at the right place. In this section, we will tell you more about the types of slots and ways to play. If you are a fan of brick-and-mortar casinos and you are used to playing like that, you will have no problem adapting to the online versions. The steps are the same: you bet money, select your pay lines and bet and hit the spin button. If you try them once or twice, you will see that online slot games are a lot more convenient. It takes you seconds to swap machines; you do not need to worry if someone else is playing on your favorite slot, no need to sit and wait. You can even swap casinos if you want to. Online casinos are cheaper to deposit, and if you do not want to do that, you can also test play for free. The bottom line is that online slots are the same as brick-and-mortar slots, but offer convenience, additional benefits, and great user experience. If you are a fan of these machines, we recommend you giving their online versions a shot. For a graphic view of our site summary, take a look at our graphic.

Big Variety

Online slots sites are very flexible, and they have improved fast over the past year. Big names like Buffalo Slots, Bier Haus, Triple Diamond ( a most popular game we have), Zeus, Kronos, Sugar Pop and even the brand new Novomatic games have joined the online slots family. Online slots are becoming more and more popular on the web. Up until recently, there were no genuine online casinos online, meaning the games and brands you would play in Las Vegas or local casinos. Now you can play some of the best Las Vegas slots online, a lot of classic ones and some you have never seen before. For example, the great Buffalo slot game – still popular, it is just an amazing game with all its features, sound effects and bonus free spin game. Other new games you can play which are also very popular in the biggest casinos in Las Vegas and Atlantic City are Where’s The Gold and Big Ben by Aristocrat Gaming as well as Queen of The Nile. Among the new favorite slot sites games are also Little Red Riding Hood, the Goldfish slot machine a well as Zuma. Zuma is available in Las Vegas, but there will be a lot more variations coming out. There are also the two video legends which have transitioned from 3 to 5 reel slots – Cleopatra, Monopoly, and Wheel of Fortune. Have you been in a casino and not trying these? If you are a fan of the 3-reel slot machine games, you will not be disappointed. The classic reel games offer simplicity and a real feeling of adrenalin when the reel starts to line up. The mechanical three reel slot games are still massively important in Las Vegas, but they are also popular online. If you are a fan of these variations, check Double Diamond and Triple Diamond. These have the same sound effects and look and feel as the original slots.

Types of Games at Slots Sites

Online you will find the same types of slot machines that you play live. Here are the most popular options: Best Online Slot Game
  • Classic Slots – These are the slots everybody has seen – the classic 3-reel slots. There are multiple payouts; they look just the same as the mechanical ones, and you can even pull the handle on the side.
  • Video Slots – These are like a video game. You can play a 5,7 or even 9-reel variety. There are multiple lines, bonus reels, and rounds. Some of the most popular video slots are WMS’ Goldfish, Bally’s Quick Hit, IGT’s White Orchid.
  • Progressive slots – This is where millions are made. You pay the full amount, and the big jackpot is comprised of a portion of the wagers of all players. This is how the pool is ever-growing, reaching staggering amounts. There is a special combination you will need to hit to win that jackpot. It will grow until some lucky player gets the winning combination.
  • 3D Slots – These are similar to the video slots, but with a better feel. You get a 3-dimensional, more in-depth look.
In addition to these types of slots, there are casinos and software providers who offer exclusive one-off machines. For example, Realtime Gaming offers special Real Series slot machines. The special thing about the series is that they award prizes at random.

Mobile Slots

Mobile is growing rapidly in popularity, and the mobile gaming industry is expected to grow even more in the next years. Online gambling and slot sites are not an exception. With more than 13 million people playing casino games every month the industry is doing well. As more and more people use their mobile devices to browse the internet, it makes sense to play on the go on slot sites with your phone or tablet, too. It is not always possible to go to your local casino, let alone destinations like Las Vegas. You cannot just take a slot machine with you everywhere you go. So, playing on your mobile device is the next best thing. And fortunately for all passionate players, slots are the majority of games at each casino. You can play slots on an iPhone, iPad, Android or Windows device. As the industry grows, there will only be more compatible slots apps available. Getting started is real simple. You either download the app from the app store or the casino or play directly in your browser. Some casinos offer the option to download the slot game via a QR code or test message. Check more details at the site of your casino of choice. Usually, on the site, you will find a list of devices the app is compatible with if they offer a free option, etc. If you already have an account at the online casino website, you do not need a new registration for the mobile version. Enter the credentials of your existing account and enjoy the game.

Free Slots

One of the biggest differences between online slot sites and their brick-and-mortar counterparts (at various countries) is that online you can play for free. Online casinos can offer free games because they do not have many of the limitations brick-and-mortar ones have, like space for example. So, you are not taking the place of any paying customer, and it does not cost the casino anything extra to allow you to play gratis. Their idea is that if you play long for free, in you might consider becoming a paying customer. Most of the slot games, variations and themes are available in a free version including the big names like Twilight Zone, Star Trek, and Monopoly.

Free Games

The free games include 3-reel slots, games with bonus rounds, video slots and much more. Progressive slots are the only ones you cannot play for free. That is because the jackpot is comprised by part of every deposit made. Many of them are part of a network, and they cannot have a jackpot triggered by free money spins. But why play for free? Doesn’t that remove the thrill of playing? Everyone have their reasons. Playing for free is a good way to test the casino software – is it fast enough, does it work well, and do they have the games and themes you are looking for? Other people may not trust online casinos, or they just want to enjoy the game without gambling. Sometimes the free online slots sites do not offer such a large selection of games. If you are looking for a wider range of online slot games, then you can register with some online casinos. They offer a much bigger selection of games. However, you need to be careful when choosing an online casino. It has to have a license, good reviews online, to allow you to cash out winnings, to have generous bonus offers and of course a great user experience.

Progressive Jackpot Slot Games FAQ

You could win a million dollar, euro or pounds jackpot in an instant, when playing progressive jackpot online slot games. For the jackpot to grow to great numbers, there need to be a lot of players and quite a lot of play time. For those who are interested in cards, there are progressive poker games online. If you want to play progressive slots for the first time, you will probably have some questions. Below you will find the most frequently asked questions slot players have and an expert answer for each one of the questions.

What is the highest jackpot ever won?

The highest PJ that has ever been won and paid out at online Slot Sites was just over 17 million euros. It was won on the Mega Fortune slot game which you can find in many casinos using the NetEnt gaming platform.

What type of PJ slots can you play online?

Most of the three reel online slot games offer a progressive jackpot. We hope to see any Fruit Machine offering such jackpots.

How can I increase my chance of winning?

The first step is to start playing progressive slots, the more you play, the higher the chances of winning the big jackpot. When you play randomly then you have the same chance of winning a standard jackpot. The more spins you play, the more chances, you will have, plus the jackpot is growing as well.

What are the payout percentages of progressive slots games?

Most games at slots sites use the players’ stakes to feed the progressive jackpot, but the percentage of the stake amount used for the purpose differs from slot game to slot game. This makes the base game payout percentage on progressive slot game lower than that on other types of non-progressive games. Keep that in mind when playing. The way to end a session with a high payout percentage when playing progressive slots is to win the jackpot.

Why can’t I play progressive slots with a bonus?

As already mentioned above a small amount of players stakes playing any progressive jackpot slot are added to the jackpot prize pool at the slot sites. Since bonuses are usually given away for free as a kind of promotion, so that new or loyal customers can play for free there is no cash to feed the jackpot. Operators and Networks will need a lot of money to feed the progressive jackpots themselves if they let players use their bonuses to play these slot games. This is why finding a casino offering bonuses that can be used on progressive slot games is rare and quite unusual. This is because the jackpot is usually won at another casino site and not the one you are playing at.

What are the odds to win a progressive jackpot?

This depends on the type of slot game you play. For example with many millions of possible reel symbol combinations, the odds of winning are in the millions to one range. So you should play progressive slots without being obsessed with winning the big jackpot. Look at the progressive jackpot as a rare bonus payout.

Which slot games pay their jackpots regularly?

You can win the most jackpots at progressive Slot Sites games which have several of them. Some of these types of games will award their two lowest jackpots every few minutes. Such slots are the Mega Moolah series from Microgaming, Marvel Jackpot and other slots themes available at online casinos powered by the Playtech software.

What are random jackpots?

Random jackpot games online are growing in number. They share a similar playing structure, and that is that the progressive jackpots are awarded to players at a random principle. So, there is basically no need to have any type of winning reel symbol combination lined up on the pay lines to be a lucky winner. At these games, you either win instantly at the end of any paid for the spin of the reels, or you need to play a bonus game first. This guarantees that you will win one of the progressive jackpots offered if the game actually has more of them.
