What are slots?

We all love to play casino games such as table games, card games, scratch card games, roulette, poker, blackjack, baccarat and many others but the kind of game that we like to play the most is of course slot games. There is something about when spinning the reel that makes us excited to land lucky combinations that will give us big wins that just keep us playing slot games non-stop, because who would not be happy to win a big jackpot?

Slot games have come a long way since the old machines in the classic land based casinos from a 3 reel game with one payline up to multiple reels slot games with lots of paylines that you can play right in the comfort of your house or any place you want to use your laptop, desktop, tablet, smartphone or any other mobile devices.

About Slot Software Companies

In these days you can play a new slot game almost every week since there are many software companies such as Tom Horn Gaming, Quickspin, Iron Dog Studios, 1x2 Gaming, Wazdan, Endorphina, Play’n’GO, Net Entertainment, Red Tiger Gaming and many more companies developing new slot games due to the high demand of players and new online casinos, sportsbooks and other online gambling sites, moreover, every month and then there are new software companies and other online casinos developing their own slot games.

Probably Fair

Many casino haters, politicians and other non-gambler persons state that online casinos and slot games are scams which is not true. There are some shady casinos yes, but you can avoid them by reading player reviews or casino reviews or by using probably fair tools if the casino provides you access to them.

Also, you can check if the casino has a gambling license or if it’s approved or recommended by 3rd party websites such as gaffg.com, Affiliate Guard Dog or others forums or blogs, moreover, software companies always use a RNG software or Random Number Generator software which is a program that will provide random numbers on all outcomes of the games including slot games, meaning that it all comes on how lucky you are and how much money are you willing to bet.

Playing for Free or for Real, your choice

When playing slot games in many cases you will get to choose if you want to play for free or with real money. Playing for free is always a good idea if the slot game has lots of features and mini-games since you can practice before the real deal and avoid losing money for not knowing what to do.

Playing online slots is a fun way to pass the time that always gives you a chance to win a big jackpot. Every spin is an opportunity to win something. As any large winner will say they didn't expect it to happen, but you can't win unless you don't play, so what can you do? Well it is very simple, play for free first and then whenever you are ready then bet some money on it, nevertheless, we recommend doing this only for slot games that have mini-games, mechanics or special features that must be learned beforehand but if it’s a slot game that only is about how lucky you are then go for it from the start.

Types of Slot Games

Let us examine the types of slots available and to help you decide which ones you will enjoy better and to get slots bonuses to build your bankroll.

Players have a choice between 3 reel slots, video slots, progressive slots, VR slots and Cascade Slots and with Rival casinos you have i-Slots. Each slot has its own special feature that makes it unique from the rest so let's dive into some various slot games available.

3 Reel Slots

Reel slots are also known as classic slots which as the name says have only 3 reels and usually come with one payline. This is how slot games looked and worked back when slots were introduced in casinos around the world.

These were so popular that they were the reason for Las Vegas expansion that saw mega casinos sprout everywhere. 3 reel slots play very fast and some players like this while others don't. The variance on these slots can be high which means you either win big when you hit or lose it all very fast, it all comes on how lucky you are and how much you are willing to bet in every spin.

Video Slots

Video slots are also known as 5 reel slots. These slots tend to offer more paylines and can be confusing at first but are fun when you sometimes win something after you thought you lost. These paylines can be as high as 15 or 20 paylines.

Video slots on average tend to last longer than 3 reel slots due to the fact it takes longer for all the reels to play plus any video animation. Also, because there are more paylines you don't always lose so fast if you do hit a bad streak. Your bets will last longer as some slots always end up paying you something for half of your spins.

The jackpots also tend to be larger with coin sizes exceeding 10,000. This kind of slot game usually comes with other mini-games inside them or with fun features that make the game more fun.

Progressive Slots

As you place a maximum bet, a portion of that bet goes towards the progressive jackpot. These progressives are usually on a large network with many players playing that contribute to the jackpot sizes. To date there have been many multi-million dollar winners online with the 2 biggest being €6.3 million at Mega Moolah at River Bell Casino and $5.5 million on the same slot at Blackjack Ballroom.

Bet sizes are typically from $1 to $5 per spin but when you play progressives you're playing only for the jackpot. You can always identify this kind of slot game in online casinos when applying the progressive filter or when the word “progressive” appears below the logo of the game.

I-Slots

These interactive slots are only available at Rival powered casinos likeSlotocash, Superior Casino or Vegasdays Casino. Some featured i-Slots are Hole in Won, Rock On and As the Reels Turn. Each i-Slots has interactive bonus rounds that let you control the outcome and payout. They are really just fancier video slots but certainly the best game is Hole in Won where you get to play mini golf for the bonus rounds.

Cascade Slots

This type of slot games are also called chain reaction slot games, rolling reels, falling reels or tumbling reels, and they work like if you were playing candy crush. When pressing spin you will have to combine the symbols in certain ways to have wins, and after you land, let’s say for example a vertical or horizontal line of 4 identical symbols you will get a win and these symbols will disappear and the other symbols that were on top will fall on those places and new ones will appear on top of them.

Cascade slot games will give you lots of small wins, so you can say most of them come with a low to medium variance. Some of the chain reaction slot games that we recommend are Ghost Glyph, Reactoonz 2, Bonanza Megaways, Viking Runecraft, Bombuster and many more. This kind of slot game tends to have many fun features that you can use to destroy or eliminate symbols that are blocking other important symbols to form a winning cluster also they may have mini-games that make the game even more fun.

VR Slot Games

Virtual reality technology has been around since a while now but just recently we have some VR slot games and even VR casinos that you can enjoy right in the comfort of your living room or any place. When playing using a VRset you will experience a 3D casino like in a real life land base casino, perhaps the graphics will not be the best ones but as time passes the quality will improve without doubts.

Some slot games that you can play with a VR set are for example: Gonzo’s Quest which is one of the favorites, Miss Midas, Thunderstruck II, Starburst and many more. This technology goes beyond slot games, so you may play other casino games such as Roulette, Blackjack, Baccarat and even Poker. It is for sure that more online casinos and slot games will be compatible with this technology in the future but for the moment we can enjoy few but good titles.

Slots bonuses

Keep in mind most casino bonuses available are for slots but not always for progressive slots. Most casinos won't offer bonuses on these games but if they are there make sure you check out listings to see at which casinos you can get some bonuses and comp points playing on progressives.

Free Spins

Free spins are the most common bonuses that you will get from online casinos or other gambling sites. Most of the time you can get them with the welcome bonus package for specific games or trendy games, or you can get them from regular bonuses or for loyalty rewards, do not forget that these free spins may come with some wagering requirements, but you can find them too with 0 requirements attached.

When playing slot games you can earn other free spins and re-spins depending on the game of course, because these features may vary depending on the theme of the game and the software developer.

Auto Spins

Some slot games have the Auto Spin mode which you can activate for a specific amount of spins, until you get a win, or simply spin the reels until you deactivate it. We strongly recommend avoiding using the previously mentioned option since where is the fun in that? There is something about the adrenaline and the rush that we get when spinning the reels that gets rewarded when landing juicy combinations.

About Slot Games

There are some features or characteristics that you should consider when playing any lot game such as the RTP, paylines, variance, player reviews and others. We will talk about a bit of these features just as follows:

RTP or Return to the player Rate

Unless you are playing for fun, you should always check the RTP of any slot game to know how good are your chances of winning or how much money you will get in return.

At the end is all about the luck but if you are going to play a slot game with an RTP of 94% your chances are not that good but if you find a slot game with an RTP of 98% then you should probably play more that game to get more winning combinations, but at the end is all about luck.

Paylines

Paylines or ways to win are an important characteristic that you must take into account when choosing a slot game to play since if there is only one payline then your chances are not that good, however, if you find a slot game with at least 50 paylines you can say that it is a decent slot game to play plus if the RTP is high too then you will have lots of fun and big wins when playing that game.

Also, believe it or not there are slot games with more than 100,000 paylines but with a moderate RTP. These types of slot games are very fun to play, and usually you can identify these slot games when “Megaways” appears on the title of the game.

Variance

The variance of the game or also called volatility, allows you to know how often you are likely to land winning combinations and how much your winnings will be so, if you are playing a slot game that has high variance you will not land many winnings combinations but when you do you can win juicy prizes or jackpots and if you find a slot game that when spinning the reels you get lots of winnings combinations with small wins them you are playing a low variance game.

So it is up to you to play a slot game with low volatility or with a high volatility since both options should be ok but when playing slots with high variance the risk of losing is higher, but again the higher the risk the higher the reward.

Mobile friendly and platform friendly

Almost all slot games are now mobile friendly meaning that you can play from your laptop, desktop, iPhone, tablets, smartphones or any other mobile devices but still there are some few old and popular slot game that may not be compatible with all devices, moreover, there are other slot games that you can’t play using Linux or other OS.

Also, keep in mind that many of online casinos and slot games were made to be used with Google Chrome so try avoiding browsers like Opera or Mozilla Firefox when playing old slot games.

Player Reviews

It is always a good idea to check what players think of a specific slot game, it does not matter if you are a pro player or a beginner because reviews are always important since you will know or at least have an idea of what kind of slot game you will be playing and what are the tricks, paylines or guidelines to know beforehand.

You can check slot reviews made from websites such as this so feel free to check out our slots review area, in there you will find all kinds of slots, from Halloween slots with few ways to win to Christmas slot games with lots of ways to win and multiple features.

Slot Tournaments

This kind of tournaments is very fun to participate in since compared to Poker tournaments or Blackjack Tournaments you can compete without too much pressure. Basically to win in these tournaments you will have to finish at the top of the leaderboard to win cash prizes or even more free spins so it all comes in how much you wager and play.

These tournaments tend to last for a week or a weekend and many online casinos offer them.

Missions or Challenges

Some casinos offer missions or challenges in which you have to play and win a certain amount of money or activate a special feature or other tasks on specific slot games to win bonuses, loyalty rewards or unlock other incentives.

Usually the slot games in these challenges are the most popular or the trendy ones. So do not miss any of these tournaments when joining an online casino because they will give you many amazing rewards and the best part is that you will have fun.
