How to Play Slots Online – the Complete Guide of Game Features

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. 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.

Slot Machine Paylines Review & FAQs

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.

What Are Wild Symbols

Slots Wild Symbols

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 symbol design.

What Are Scatter Symbols

Slots Scatter Symbols

Scatter symbols are another great feature of online slot games. They can generate a number of different outcomes: Scatter symbols could 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.

There are exceptions however; 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.

Tips for How to Set Your Bets on Online Slots UK Games

When you want a chance to 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:

Explanation of Odds of Winning Two Main Factors

Two of the most fundamental concepts to understand about slot machines are ‘return to player’ and ‘hit frequency’. Together it gives a general idea of how "generous" a slot machine could be. Both are per machine.

What is Return to Player (RTP)

RTP – RTP stands for Return To Player. The RTP percentage is a measure of the percentage of stakes a game returns to players (generally over a minimum of one million plays), and is a generally accepted guide to how a game will perform.

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.

What is Hit Frequency

Hit frequency is the percentage of times a slot machine will stop its spinning on a winning combination. Meaning, if a slot machine hhas 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 RNG (Random Number Generator).
