Play slots online – it’s never been better - life is good.
This is your chance to understand how online slots work. We’ve put together a comprehensive guide of online slot machine games – main features, tips for how to set your bets, breakdown of odds and FAQs. It lays down the basics first, and then goes in detail into the different features of the game.
You are probably familiar with the Classic Slot Machine. Three reels spin, and in order to win you need to get three identical symbols lined in the middle. When you play slots on the web, well, it’s a whole different game.
Online slots UK games, or as they are also called, Video Slots, are more than that. First of all, most have five reels. The second thing to understand is that the winning streak doesn’t need to appear in the middle row. It can be in the top or bottom row, it can be diagonal or in zigzag. Also, the locations of the winning streaks change from one slot to another.
Welcome to the slots online world where everything is possible. How would you know you have won if there are so many different winning options that change from slot to slot? Worry not; you will be let known of your every win by the game’s software.
Let’s start with the most important aspect of playing online slots UK.
Let’s start with the most important aspect of playing online UK slots – paylines. This determines so much of the game you’re playing, how much should you bet on each spin, what are your chances of winning, how quickly the game progresses and the level or risk vs. chance. First thing, definition of paylines.
As mentioned above, in online slot games there are various possible winning lines. Usually, there are 9 to 30 different winning lines for each slot game, which are called paylines. They look something like this:
In this game above there are 25 different paylines. Meaning, with every spin you have twenty-five possibilities of winning. As you can see, some paylines run straight, some diagonal while others zigzag the reels. The important thing is, if you get any of these 25 paylines, you win.
Another important thing to understand is:
You can get a winning streak anywhere along the payline. The matching symbols don’t even need to be next to each other, or in any specific place along the payline.
Let’s explain this. In the game shown above there are 25 paylines. Meaning: with every spin you have 25 different ways to win. Before every spin you need to decide on how many paylines you want to bet; it can be on only 3 lines, or 18. You can select any number from 1 to 25. You can’t choose which lines you want to bet on, just the number.
If you bet on 1 line, you play for 1 coin in every spin. If you bet on 6 lines you play for 6 coins in every spin. The more Pay Lines you bet on, the higher is the amount of money you spend on every spin.
There is no definitive answer here. Some would say that you should always bet on the max number of paylines. That way, you are more likely to win with every spin. That is true, but remember you are betting more money on every spin. Others would say that you should bet on just one single payline per spin, since each line is weighed independently in the win-or-lose equation. That is also true.
The decision is yours. You should give it a try and see for yourself what is more enjoyable for you. Some find it boring to play with just one payline and enjoy the excitement and fast-pace of a multiple payline game. Others prefer to stretch the game as much as possible; the way to do that is to bet on one line at a time.
The next frequently asked question leads us to the most exciting feature of slots online, the feature that distinguishes them even more from land-based casino slots:
Lucky for you, and for everyone else that plays slot machines online, the Wild Symbol comes to the rescue. You can read more about it below, but let’s quickly explain that a wild symbol can ‘stand-in’ for any other symbol. For that, you can win in online slot machines with two identical symbols and one wild symbol.
A Wild Symbol is basically anything you want it to be, or actually, any symbol the software chooses it to be. No matter how you look at it, wild symbols increase your chances of winning. Here’s how.
In slots you need three identical symbols in order to win. But - you can win with only two identical symbols if along the payline you also get a wild symbol. Wilds can stand for any other symbol. If you get two cherries and one wild - you win! If you get one spade and two wilds – you also win!
The last thing to know about wild symbols is that they come in all shapes and sizes. Each slot has its own wild design.
Scatter symbols are another great feature of online slot games. They can generate a number of different outcomes: Scatter symbols can award you with coin prizes, free spins or bonus rounds.
In order to get these prizes, you’ll need to have 3 or more scatters appear anywhere on the online slots reels, in no specific order or location. (There are some online casino slots UK where 1 or 2 scatters are enough to generate a small prize, but that’s not the norm.)
Important to know: Scatter symbols don’t need to land on a payline. As long as they are visible on the screen, they count.
As mentioned, scatters can generate free spins and bonus rounds. Another common activation of scatter can be that of a multiplier – it multiplies your win x2 or x3. The best part is, scatters multiply your entire win from the round, not just that of a specific payline.
The only downside is that wilds cannot substitute for scatters. Three scatter symbols are needed to generate a winning feature, and in this case the wilds can’t stand for a scatter; you’ll need all three. Worry not, they’ll show up, they always do.
When you want to play slots online win real money you can start each online slot game by deciding the amount of money you wish to play with. There are two steps to complete:
1. Deciding on the Bet Amount. In every slot you will have Minimum and Maximum bet points. For example, from 0.5 to 100 coins. Meaning, you can bet half a coin on every spin, or 100 coins, or anything in between. Needless to say, the higher your Bet Amount is, the higher the reward will be.
2. Next, you need to decide on how many paylines you want to bet. Crucial to understand: the Bet Amount is for a single payline. As explained in the payline section above, most slot machine games give you the option to decide with how many paylines you wish to play, and you’ll need to multiply that by the bet amount. If you decide to play with 2 coins and choose five paylines, you will bet 10 coins on every spin. The higher the risks are, the higher the rewards.
Once you made these two decisions, you are ready to play. The only other decision you’ll need to make is a very simple one: to click yourself every time on the Play button or select the AutoPlay feature.
Two of the most fundamental concepts to understand about slot machines are ‘return to player’ and ‘hit frequency’. Together they give a pretty accurate picture of how “generous” a slot machine is. Both are per machine. Understanding how these two factors work together will greatly help you in choosing which game to play.
RTP – Return to Player - is the percentage of wagered money that is paid back to the player – per machine, and in the long run. This is crucial to understand. RTP isn’t calculated per player or per session, but rather per machine.
A machine with a statistically 90% RTP means it will pay back in winnings 90% of the money players wagered on it. The higher the RTP of a certain game, the higher your chances of winning on that game.
Important to note: online slot games have a much higher RTP than land slot machines.
To find out the RTP of an online slot game, click the “i” or “?” button in the main screen of the game. All online slot games must display their RTP.
Hit frequency is the percentage of times a slot machine will stop its spinning on a winning combination. Meaning, if a slot machine has a Hit Frequency of 25%, it will generate a winning combination of approximately 1 out of every 4 spins.
The average here varies widely. Let’s say it is between 10 to 30%, for UK online slots.
Important to note: high hit frequency doesn’t necessarily increase your overall winnings. Why? Because it also depends on the RTP and the size of your winning.
Combining both RTP and Hit Frequency gives you an edge when you play slot machines online.
