    How to Play Online Slots

    Slot games are probably the easiest game to play at our top rated casino sites. It’s a game of chance, and there is no real strategy to implement to boost your winnings. For new players, it can still be a bit confusing, and we have therefore created a simple guide to get you started. You can also take a look at our video guide further down on this page.

    Time Required: 20 minutes  |    Tools Required: Mobile or computer  |    Funds Required: €/£ 10
    Step 1

    Choose the Best Slots Games

    First, you have to find a good casino to play at. We recommend you take a look at our top list above, where you can find our best online slots sites. Make a deposit and pick the slot you want to play.

    Step 2

    Check the Paytable

    Before playing, we recommend you take a look at the game’s paytable to see the winning combinations. Take a look at the game instructions to see what kind of bonus features there are and where you’ll find the real big winnings.

    Step 3

    Select Coin Size

    Adjust coin size and bet lines to decide how much you want to bet each spin. Some games have fixed lines, and you can only decide the coin size. Make sure you keep your bankroll in mind when you decide how much to bet.

    Step 4

    Spin the Reels

    Click the “spin”-button to play the slot. After each spin, you’ll see how much you won or whether you lost. To make the game more efficient you can use “auto spin”-mode, which let you preselect how many spins you want to play.

    Video Guide How to Play Slots Online

    We have created a video guide to show you the very basics of how to play slots online.

    A Brief History of the Slot Machine

    The first slot machine called the ‘Liberty Bell’ was invented at the turn of the 20th century by Charles Fey, a young mechanic from San Francisco, California. Up until then, the original machine was a 5-reel game based on poker that didn’t pay out any real money winnings.

    Charles Fey’s invention had three reels and an arm on the side to start the reels spinning. Rather than the complicated format of poker, a player now simply needed three matching symbols to win: hearts, horseshoes, spades, diamonds, or liberty bells, which also gave the machine its name. Winnings were paid out in cash, and now it was much easier to hit a winning combination.

    Today, slots make more than 70% of turnover.

    Online Slots Today

    The slot machine has undergone a massive evolutionary change since it was first invented in the 19th century. The dawn of a new digital age gradually allowed developers to take the traditional ver-sion of the one-armed bandit and expand on it in a multitude of ways. With technology driving the online gaming industry, many unique games and innovative features were introduced to satisfy every type of player. In fact, there are so many online slots available these days that the choice can be overwhelming.

    Here at MrCasinova.com, we have taken the time to review all the latest slot games and give you the low down on each one. No matter whether you’re a comic book fan, a movie buff or a lover of fairy tales, there’s a slot game out there that’s going to tickle your fancy!

    Top 10 Free Slots for Fun

    We offer an endless portfolio of free slot games. Our selection is jam-packed with brilliant titles — including the latest game releases from the biggest developers — that can be played for fun or to practice before you play slots for real money.

    This is a top ten (10) list of online slots games MrCasinova.com has to offer:

    Online Slots Gameplay

    These days, slot games feature some of the most incredible graphics and interesting game elements that catch your eye. But for a slot to really shine, the vibrant and colourful visuals have to be backed by dynamic gameplay. We particularly love slot games that take you on a journey through multiple levels with plenty of opportunities to unlock bonus features, such as free spins and mini-games.

    While we’ve been investigating all the new online slots 2021 has to offer, we’ve seen plenty of slots that offer this popular type of extended gameplay — and we’ll be sure to point you in their direction.

    Reels and Paylines

    The traditional set-up for one-line slot games is 3 reels, 3 rows and 9 paylines. For a win, you need to get a line, either vertical or horizontal, of 3 matching symbols. The payout will depend on which symbols you land, as some have a higher value than others. For more information on fast payout casinos check out our guide.

    Multi-line slots can come in all shapes and sizes. They usually have five columns and three to five rows. Multi-line slots are distinguished from one-line slots by larger numbers of lines — five, ten, twenty, or more. Winning combinations can be achieved vertically, horizontally, or diagonally.

    More Paylines and more Features

    With more paylines and more features, multi-line slots have taken over their less complex predecessors in terms of allure and excitement. With multi-line slots, winning is not a matter of lining up a set of cherries. Instead, there is an infinite array of ways to win, which usually offers a lot more entertainment.

    Not to mention that players’ win potential is usually a lot greater since there are more paying symbols, which means the increase of winning combinations. So it comes as no surprise that at MrCasinova.com, we’ve seen a growing number of slots shrug off this set-up in favour of more reels and rows, leading to a much greater amount of paylines.

    Symbols and Wilds

    play online slotsWhen you’ve hit on a slot that you’d like to play, it’s important to check the value placed on each symbol within the game. To get the big wins or hit the mega jackpots, you’ll need to land the highest paying symbols. Two of the most important special features to look for when choosing an online slot are the wild and the scatter.

    A wild symbol can act as a substitute for any other symbol in a slot. Its purpose is to fill a gap on the reels in order to form a winning line. For example, if you have a symbol on reels one and three, you will need the wild to land on reel two to create a winning combination.

    Expanding wilds take this one step further by filling up your reels and creating blocks of matching symbols, making for potentially jaw-dropping winnings.

    A scatter symbol is a special feature needed to unlock different welcome bonuses. It needs to show up any-where on the reels to lead you into a bonus section or unlock the free spins round, among other bonuses.

    Both the wild and the scatter symbols are represented by specific graphics that are usually unique to the particular slot title’s theme.

    Jackpot Slots Online

    online jackpot slotsSlot games can have either a fixed jackpot or a progressive jackpot. A fixed jackpot, which can also be referred to as a non-progressive jackpot, is set at whatever amount the casino sees fit. The value is built into the game and does not depend on bets made by other players.

    A progressive jackpot grows each time a player makes a bet on the slot game, whether it’s at the same casino or somewhere else in the network until someone triggers the payout feature.

    Since the odds of winning on a progressive jackpot are extremely low, if you’re going for the mega jackpot of any game, especially a progressive jackpot game, you’ll need to place the maximum bet.

    RTP of Slot Games

    While some casino players like the adrenaline rush every time they place an important bet and are not actually interested in the payout, most people play casino games to make a profit. In order to maximise your chances of winning, you need to pay attention to the RTP, or Return to Player rate.

    A game’s RTP listing is stated as a percentage and is generally measured over 10,000 or 100,000 games or greater for compensated and random machines respectively, dependent upon their category. For example, if you were to make a thousand 1€ bets on an online slot with an RTP percentage of 96%, you would expect to win 960€ back.

    RTP gives you an indication of how likely it is that the slot you are playing will payout. The higher the percentage, the more you can win, so choose slot titles that have the highest percentage of RTP — 94% or more.
