Types Of Online Slot Machines And Games
Online casino games and slots specifically come in all sorts of different varieties. Whether you are after a straightforward and more simplistic time or a narrative-driven modern title, you have so much choice as a UK player.
Below are the main types of slot games that you will come across online:
Three Reel Slot Classics
Multi-Payline And Multi-Reel Slot Games
Progressive Jackpot Slots
Progressive jackpots are a unique brand of jackpot slots that can result in some truly huge payouts. These are readily available and these have top prizes that keep growing until they are won, which in some cases is millions of pounds.
Iconic games such as Mega Moolah are classics of the genre and are still incredibly popular to this day with many casinos linked in so-called networked jackpots – these often result in some massive wins being up for grabs with the pot being funded through multiple websites. All major providers have some progressive jackpot slots, with fresh releases becoming increasingly common.
The Best Payout Slots
We have handpicked five of the best slots around to play if you are looking for high payout rates – each has above-average RTP as well as gameplay with fantastic depth.
Though the very high volatility may put off many players, the 99% RTP of this game is one of the highest possible, meaning that, hypothetically at least, Book of 99 is a slot that should see regular payouts – the maximum prize on offer is 5,000x your spin stake.
A staple at all major casinos since its 2014 release, Book of Dead is a certified classic to the extent that it is often included as part of casino welcome bonuses. Its 96.21% RTP is not the most generous on this list but the high volatility and decent stake limits mean that this has good payout potential.
NetEnt’s retro-themed slot is one of the most memorable in the company’s impressive repertoire. As well as the 99% RTP – which is rare and the highest that players can expect from a game – Mega Joker has a progressive jackpot and a fantastic array of features; it can be found at most big-name casinos.
Angling-themed slots are becoming more and more popular but Big Bass Bonanza was one of the first to really see success. Pragmatic Play’s 2020 effort has a decent RTP of 96.71% and high volatility. When you add great stake limits and uncomplicated gameplay, this is a fine choice for slot fans – the inclusion of wilds and scatters adds extra earning opportunities.
Mega Fortune is another brilliant NetEnt release. With Vegas imagery, this is very much a glamorous experience on the reels and there is a maximum win amount of 80,000x which is among the biggest around. When you combine that with a progressive jackpot, 25 paylines and a superb wheel bonus game, few other slots match up to this experience.
What To Expect At A Top Slots Casino Site
A Large Range Of Demo Slots, Perfect For Practice
So, keep an eye out for casinos that offer demo play so that you can get up to speed without any financial risk.
Fantastic Online Slots Game Software With Maximum Security
With this, every UK-licensed casino should have you covered as they must all conform to the highest standards, but it is still worth repeating: make sure that the site that you are using is partnered only with casino software brands that have the correct security and encryption levels.
In short, only play at brands that can be trusted and are licensed by trusted bodies; this will ensure that your play-time is both safe and fair.
Top-Quality Customer Service
Great Welcome Bonuses To Use On High Payout Slots
Online Slots Tips And Tricks
Online slots are perhaps the simplest game mode Online slots are perhaps the simplest game mode at casinos and no prior knowledge or skill level is necessarily required – this is also one of their main attractions. But, if you want to know how to win at slots then we have five tips for you to take on board.
Demos allow you to determine whether a slot is fun to you, the most important aspect of all. You’ll also be able to accurately tell how a slot’s volatility affects your winning chances over a certain number of rounds and a few more questions might be answered. Even though it may not be possible to develop a real strategy, as slots depend on luck and not on player skill, you can still test what’s possible at a slot with the budget you have and discover strengths and weaknesses.
Bonus features are the way that you are going to land big wins on slots, so it is always a good idea to see what specific elements a title includes before you play. Free spins are, of course, very common but you may also wish to see if scatter symbols and wilds are there to increase the likelihood of a win. Similarly, if you want a straightforward time on the reels then you may want to find a game that has only basic features.
You will probably already be aware of these terms, but both RTP and volatility are crucial to understanding the type of experience that a slot provides. The latter especially will have a material impact on how frequently the game pays out – low volatility will shed smaller wins and often, with higher volatility games doing the opposite.
As this page shows, it is very straightforward to get hold of a casino bonus that lets you play on slots. Arguably the best way to do so is through grabbing an offer that both increases your deposit by a certain amount and also provides free spins. You will then have the chance to play some hugely popular titles, though terms and conditions will need to be fulfilled if you want to make a cash withdrawal.
Though our tips can help you to get the most out of your online slot session, it is imperative that you are realistic about your chances of winning big. Progressive jackpots, for example, can offer some tantalizingly big wins but the reality is that very few players get close to claiming one. When playing slots it is important to gamble responsibly by sticking to your budget and not chasing losses – especially as this game mode is entirely down to luck.
