RTP vs. Volatility
Before playing at the best slot sites UK, you should inform yourself of their return to player (RTP) rate and volatility level. Knowing this information gives you more guidance on how to properly set your wagers per spin. Here is some further insight about RTP and volatility in online slots.
RTP
The return to player rate is a percentage indicating how much an online slot is expected to pay back to you across long term gameplay. So, as an example, a slot with a 97% RTP rate will theoretically return £97 for every £100 you wager on it. However, it is vital to note that the figure is a statistical average, which is calculated over millions of spins on the game, rather than a guarantee of payouts from an individual round of gameplay.
You need to keep the RTP rate in mind when betting on a slot because it highlights the game’s potential payout efficiency. The slot games with higher RTP rates tend to offer better long-term value, while those with lower RTP rates may have less frequent payouts. Of course, RTP has little to do with short-term wins, but it can help with determining which slots to play. This is especially true for players looking to maximise their chances of winning or looking to extend their bankroll.
The RTP rate of a game is often linked to the volatility of it, which is why you need to consider both these factors before gambling on at the best slot sites UK.
Volatility
The volatility of a slot describes the level of risk and reward within it. Through this, you can understand how often and how much a slot is likely to pay out when you play. That’s why it is crucial that you understand a game’s volatility, so you can pick one that matches your style of playing. The three types of volatility are:
- Low –Providing smaller payouts on a more frequent basis. Low-volatility games are better for players who prefer taking it steady with their gambling and reducing their risk.
- Medium –A balance between low and high, providing average payouts at a steady pace.
- High –Offering higher payouts but less frequently. A high volatility slot is one that appeals to players who prefer high risk and the chance of high rewards. It is most often players who can handle longer stretches of gameplay without wins that play these slots.
Make sure you select the best online slot sites UK with the volatility level that caters to your risk tolerance. Volatility directly affects your bankroll management and overall gaming experience, which is why you need to factor it in alongside a slot’s RTP rate.
Guide to Online Casino Slots
There are certain features of online slots that you need to know about before you start playing them. Here, we’ll dissect some of the details built into games found at the best slot sites UK.
Themes
The theme of an online slot game is its creative foundation. It is this that operates as the base, forming its look, feel and the overall atmosphere when you play. You can experience various themes in the best online slot sites UK, ranging from ancient civilisations to mythology and adventure to pop culture. There are even branded slots, basing themselves on television shows, films and musicians.
A strong theme in a game enhances the overall immersive feel of it, bringing together visuals, sound effects and bonus features. Many gamers choose a slot with a theme that resonates with their personal interests.
Types of Reels
The reels in a slot game are the spinning columns featuring symbols. Traditional slots will often include three reels, while the more modern releases contain five reels or more. Some of the games also introduce innovative features like the Megaways mechanic, incorporating thousands of ways to win. Cluster pays or pays anywhere mechanics can also come into play, with symbols forming wins by clustering or landing anywhere on the reels.
The type of reel setup influences the complexity of gameplay, as well as the potential win frequency and payouts. Choose a slot that offers a reel set you enjoy experiencing at the best slot sites UK.
Auto-Spin Function
By using the auto-spin function, you can automate spins for a set number of rounds. This means you don’t have to press the spin button each time. You can usually customise the conditions of auto-spin too, with functions to stop the autoplay after you achieve a big win or when you trigger a bonus round. This makes it much more convenient, especially if you prefer a longer, uninterrupted gaming session at the best slot sites UK.
The auto-spin function won’t change a game’s odds or the RTP rate. It simply acts as a way of streamlining your gameplay.
Payouts
A payout in an online slot refers to the money you win from matching symbols on the paylines or from experiencing bonus features. Each slot comes with its own paytable, highlighting the rewards each of its symbols can provide when forming a combination. Payouts will depend upon a slot’s RTP rate, volatility, your bet size and the mechanics within.
Lower volatility games often provide more frequent, yet smaller payouts. High volatility games are the opposite. The inclusion of a progressive jackpot in a game will also affect its payout structures.
Symbols
The symbols in an online slot are what drive wins. Each game has its own, often thematic, symbols to spin into view on the reels. Landing these on a payline or way to win can provide a payout.
Wild symbols and scatter symbols can also appear in many online slots. The wild usually substitutes for all the basic symbols, helping you to create wins. Some of them will also expand across an entire reel, stick to the reel for a certain timeframe or come with win multipliers.
Scatters can land anywhere on the reels and still provide a payout. They can also activate bonus rounds, such as free spins, when a certain number land on the reels.
Bonus Rounds
Special features in online slots often go by the name of bonus rounds, providing extra winning opportunities at the best slot sites UK when they trigger. The most common type of bonus round is free spins, where the reels spin without your money being used for them. Free spins rounds often come with multipliers, expanding wilds and other extra features.
Bonus games in slots can vary, with some being “pick me” mini games and others being interactive adventure rounds linked to the game’s base theme. Some bonus rounds at the best slot sites UK, also unlock progressive jackpot rewards or prize wheels to benefit from, breaking up standard base gameplay.
Jackpots
A jackpot serves as a slot’s largest prize available. This will pay out when specific conditions are met during your gaming session. A fixed jackpot pays out a set top prize, while a progressive jackpot grows over time. Every wager placed on a progressive jackpot game has a small part taken from it to contribute to the pot.
Progressive jackpots can reach massive levels, paying out life-changing wins to players. Slots like Mega Moolah by Microgaming and Mega Fortune Dreams by NetEnt are both examples of popular progressive games like this.
