1015 Video Slots : Online Slot Reviews & Free Play

Back in the day, if you wanted to play slots you had to go to your local casino. Here, you found old fashioned one arm bandits, on which you played a basic 3-reel game. In this day and age, you are now not even required to leave your house in order to gain access to such games. You can easily play from  the comfort of your own home using your computer or even your mobile phone. Slots that you can play within online casinos are known as online slots, which are designed and created like they are computer games, as well as being full of features, bonus games and many pay lines. Although the difference between online slots or video slots and mechanic slots is great, the goal is still the same – to get as many of the same symbols in lines as possible in order to win big.

Video Slots Guide – The Basics | How to play online slots

Before you start playing online, customers must decide which slot games they wish to play, as well as if they want to play for real money or simply for fun. As soon as you decide which slot you want to play, it is time to go to your favourite casino and select your preferred slot. Next, you must decide how much you wish to bet, before clicking on the start button to start spinning.

Slot Machine Anatomy

Bet sizing and Pay lines of Video Slots

There are slots where you can decide how many pay lines you want to play with, however most will let you play the full amount, without giving you the option to change them. Although, if you have the choice regarding this decision, it is always recommended to play with all pay lines, as this often brings about the best results. Meanwhile, bet sizing will depend on your bankroll and ultimately, what your goals are. If you want to play for a long time, it is better to bet small, allowing you to stay involved for more rounds. However, if your goal is to win big, it can be better to stake a larger amount too.

How to place bets using slot machines

To place bets using your favourite slot machines, you must first select the number of coins that you wish to stake, along with the value of such coins. Some slots will not use coins, however you must still choose your betting amount. You can do this by simply clicking buttons located at bottom of the screen, which are often next to the spin button.

Return to Player and Random Number Generator

Every slot has an RTP (Return to Player), which is the percentage of wagered money that will be returned to the player. For example, if the RTP is 95% and you play 1000 spins at €1 each, you should get €950 back. Unfortunately, this is not always the case, because of the number of people participating. You can always find the RTP of a slot in the information provided by the particular provider. Usually you find this information by clicking on the information button (i). Meanwhile, all slots have a Random Number Generator (RNG), which produces a random series of numbers the moment you click the spin button. The Random Number Generator doesn’t have a memory, so each spin is totally random.

Hit Frequency

Hit frequency is the figure that shows punters how often a winning combination will appear on a particular online slot machine. The higher the number, the more likely it is that a winning combination will show.

Wilds and Scatters

Wilds and scatters are special symbols that can help you in achieving big wins. Wild symbols usually substitute all symbols except the scatter symbols. Scatter symbols are needed in order to reach bonus games and other features.

Bonus Rounds

Bonus rounds are spins that you can play as a bonus feature when using an online slot machine. In general, such bonus rounds are triggered by spinning three or more scatter symbols during a round. Winnings from these bonus rounds are calculated as one significant win.

5Reel slots

5-reel slots are now among the most popular online slots around. As you can tell from the name, these slots have 5 reels instead of 3, resulting in more possibilities when it comes to wilds and scatters, as well as increasing the number of pay lines. The pay lines on 5-reel slots can go up to as much as 50, making them more lucrative than standard 3-reels.

Slots with 243 ways to win.

243 ways slots are slots featuring no pay lines, where customers come out on top when matching symbols in any position, on three or more adjacent reels, starting from the leftmost reel and ending on the rightmost reel. These slots have 5 reels and each reel has 3 visible symbols. As a result, if you have more than 1 visible symbol on the reel, then you have two ways to win. If you have a full screen with the same symbols then you have 3x3x3x3x3=243 ways to win. In this case you will win 243 times the winnings for one line.

1024 ways

1024 ways slots were created in order to offer even greater winnings to customers. This form of slot still has 5 reels, but they also have 4 visible symbols, instead of 3 as found on 243 way options. Here you also need to have matching symbols on three or more adjacent reels, while because there are 4 visible symbols, the ways of winning are up to 1024. 4x4x4x4x4=1024 ways.

Bonuses & Promotions

When you start playing online slots with an online casino, you will see that there are many bonuses on offer. We will now explain the most common bonuses to you:

Deposit Bonuses

When you receive a deposit bonus, it means you must deposit a certain amount initially, with the online casino offering a percentage of it as bonus funds. For welcome bonuses, it will always be at least 100%. However, If your casino offers regular bonuses, they may be at 50% or less. Bonus cash must be wagered a set number of times before any withdrawals can be made.

Extra Spins with Deposit Bonuses

Free spins, sometimes known as bonus spins, are now offered by a large number of casinos as part of their welcome package. Spins represent a specific value per spin, which will vary depending on the bonus received. Finally, winnings from bonus spins usually need to be wagered using real money.

No Deposit Cash Bonuses

A no deposit cash bonus means that the online casino will give you money without having to make a deposit. This bonus is usually given to new players in order to test out the casino, or to very valuable players. The money you receive also need to be wagered before it can be withdrawn, with the major advantage of such offers revolving around the fact that no deposits are required.

Extra Spins without Deposit Bonus

Extra Spins without a deposit are often offered to new players in an attempt to provide a warm welcome to their platform. Meanwhile, casinos will also promote their new slots by giving free spins to players on a regular basis. This is in order for players to gain an understanding, without actually having to spend any of their own money.

Real Money Slots vs Free to Play

Most casinos offer you the chance to play their online slots for free, allowing you to get a balance between different slots available. This will give you the chance to try out a slot before you play it, as well as the opportunity to get familiar with them. Punters are also able to learn pay lines, along with the which symbols are the, as well as the difference between the bonuses on offer. Meanwhile, It’s also important to choose the right slot (if a slot has multiple bonuses), so that you understand which bonus gives you the most value and even more importantly, the most fun while playing. It is important to know that when you play for free, that this is something different than playing for real money. The “play for free mode” is created so that a player can discover the game, as well as understanding all the features that the game has. This means that during this mode, you will gain access to more features and more winnings than when you play for real money. As a result, it is worth keeping in mind that when you switch from the play for free to the real money mode, the game features won’t appear as often as before, while your winnings won’t be the same either.

Online Slots mobile vs desktop

Butterfly MobileWe live in a time where we can’t imagine living without a mobile or tablet. We use it for everything from social Media to reading the news, as well as searching the internet. So, it’s no surprise that we also like to play our favourite slots on our mobile device. When online casinos first started, everything was made to give the best experience while playing on your desktop or laptop, with mobile phones having only existed to make calls or send a text message. However, things change and our mobile phone is nowadays more important than our laptop or desktop, with many of us not even own a computer anymore. Online casinos and slot providers noticed this also, realising that they had to go along with it in order to not loose customers. This is why there is now not a casino available where you can’t play using your mobile phone. A lot of casinos created special apps for their slots, where customers can easily browse through their favourite games or search them by name. Slot providers also went along with this new trend and redeveloped a lot of their games for mobile purposes. They called these ‘’Touch’’, with names such as NetEnt Slot Starburst being among the most popular today. However, not all casinos developed app and not everyone wishes to download further apps onto their devices. This is not a problem however, with casino games being available through mobile browsers too. Unfortunately, not all slots are offered on mobile browsers or apps, but most of the popular names are.

Online Slot FAQ

What is a progressive jackpot slot?

A progressive jackpot slot is a slot with a jackpot that grows fast and high. For every bet placed a small amount of the bet goes to the jackpot. The jackpot can grow fast because the slot is offered on multiple casinos and they are all in line.

What are bonus rounds?

Bonus rounds are spins where you get as a bonus feature while playing on a slot. The amount of spins depends on the bonus. Since you don’t pay for spins in the bonus rounds, all winnings are collected as one big win.

Is playing for free the same as playing for real money?

No, it is not. If you play for free, the casino really wants you to get to know the slot. That’s why you will receive more bonus games and wild features than when you play for real money. This is also so that you will understand how the game works before you start playing for real.

Tips for Playing Slots

Before you start spinning on your favourite slots, we will provide some great tips, so that you will be fully prepared to scoop that big win.

Bet on as many pay lines as you can

We will start with the most obvious.  The more pay lines you bet on, the bigger the chance that you will get a good combination of symbols. That’s why it is the best option to play the maximum pay lines. Some slots won’t even give you the choice to change the amount of pay lines. You can decide the number of your total bets by changing the value of the coins or pay lines.

Make use of special features

A lot of slots offer a lot of special features. These are there to give you the chance to earn big wins. Most big wins are won in the special features. Try to use them as much as possible.

Check the rules before you play

Before you start playing, it is important to know everything that there is to know about the slot. This is especially true when the slot has a lot of different features and scatters. Read the info session beforehand, which you can always find when you open the slot. This is how you know what to do when you get the features and you can find the pay lines and different combinations too. Meanwhile, another important fact is that you can find the pay table, so you will know which symbols give you the big win.

Practise with free play

Almost every casino gives you the opportunity to try slots for free, so it is important to take advantage of this option. Free game modes are made to show off different titles, meaning that you will receive features and scatters more often than when you play with real money. Because you get them so often, you will learn everything about the different features, allowing you to be as prepared as possible before you start playing for real.

Mind the RTP

Before you start playing, check the RTP (return to player) of the slot. The higher the RTP, the bigger the chance you will have winnings during the game. Meanwhile, If the RTP of a game is very low, you should realise that the chances of winning are even smaller. You can always find the RTP of the slot in the information section, with every slot provider being obliged to mention this information.

Don’t get attached to one game.

A typical rookie mistake is playing the same slot for too long. Of course, we all have our own favourites and sometimes its hard to leave him, but you must be smart. So, make a list with a couple of slots you really like and don’t be afraid to add new ones to the list. When you start a session, agree with yourself the amount of money or spins you wish to play. Also decide when you want to cash out when a slot is giving you good winnings. Finally, in general, is it very wise to change slots after you just received a nice bonus game with a good win.
