HOW TO FIND THE PERFECT SLOT MACHINE

Finding the perfect slot machine to play is a process. You should compare online casino sites and their range of slot games.

It is beneficial to choose casinos that have a large library of different online slot games. We also recommend picking a casino that stocks slots developed by a large selection of software providers.

This way you will more easily find the slot machine that is perfect for you. Below we have listed a few main criteria’s to have in mind when choosing a new slot machine to play.

PLAY A MEGAWAYS SLOT

Megaways slots are among the most exciting slot machines in existence. These slots offer you hundreds of thousands of different ways to win and sometimes even unlimited wins.

Megaways slot games also offer many unique slot features including cascading reels which have the potential to increase your wins.

You can find our top 15 list of the best Megaways slots here.

ALWAYS CHOOSE A SLOT MACHINE WITH A HIGH RTP

Today, the competition is stiffer than ever between online slots providers. This pushes the game developers to always provide better slots with higher average payouts to the casinos and their players.

It is simply not enough for a slot machine to be just entertaining. Their slots must also have a fair & decent RTP (return to player) to stay competitive.

The average RTP on most slot machines are around 96%, but it is possible to find slots with an RTP of up to 99%.

Before playing a new slot, always look at the RTP of the game. You will find it easily, because the slots providers are required by their license to clearly display this information for all players.

See our top 15 list of high RTP slots here for some quality options. All slots in the list have an RTP of 97%+.

SEARCH FOR SLOTS WITH THE BEST PAYOUTS

It will not surprise you to know that different slot machines will offer you different payouts. The payout of a slot game determines how much you can potentially win by playing.

The best online slots will give you the opportunity to win big and this means that they will contribute a large potential payout. These slots are known as high payout slots and are among the most popular around.

Some slots have payouts which can reward you with over 100,000x your stake. Ideally, you should look to play slots which can offer potential wins of over 10,000x.

LOOKING FOR ACTION? CHOOSE A HIGH VOLATILITY SLOT

If you like a lot of action and are ready to dig deep in your bankroll for a potential big session, then you will enjoy high volatility slots. These slot machines tend to offer huge multipliers and exciting bonus rounds.

Ideally you want to choose a high variance slot machine with decent RTP. A good high variance slot machine will give you a payout of 95% and upwards.

Be aware though, these slots have their high variance label for a reason. If there is a chance to win big, the chance is even greater that you end up loosing your deposit. A good slots provider that focus on high variance slots is NoLimit City.

ENJOY PLAYING FOR A LONG TIME WITH SMALL AMOUNTS? LOW VOLATILITY SLOTS ARE FOR YOU

Low volatility/variance slot games are known for their consistent but low payouts. Put simply, you are much more likely to trigger lots of wins by playing slots with low volatility, but the downside is that payouts for each win are likely to be low.

These slot machines are great for players who like long slots sessions mixed with low wins/losses. Low variance slots will usually come with low minimum bet limits too, so they are really great for players with smaller bank rolls who do not want to risk huge gambles with larger amounts of money.

ARE YOU A HIGH ROLLER? PICK A HIGH LIMIT SLOT

If you are on the lookout for a slot machine which will offer you a large maximum bet per spin, then you should check out high roller slots. Some high roller slot games will allow you to bet up to £500 per spin.

We would always recommend to pick a high limit slot which also comes with a high RTP.

Please play these slot games with caution. Betting the maximum amount per spin always has the opportunity to end in large losses.

KEEP AN EYE OUT FOR THE LATEST SLOTS

Every month, slot machine developers release new games. In many cases, these slots are almost exactly the same as the regular old games available on the UK gambling market, but sometimes new and innovative slots are released.

The new slots therefore have the potential to offer players a fun and interesting gaming experience. However, due to the high number of new slots sites being launched, it can be difficult to choose the right one.

To increase your chances of making a successful choice, we recommend reading slot reviews of the games you are interested in playing.

THE DIFFERENT TYPES OF SLOT GAMES

In order to maximize the entertainment, it is important for you to recognise the types of slots available. The most common type of slot machines are video slots, followed by classic slots and then progressive jackpot slot machines.

The type of slot machine you choose should depend on your needs and which of them can provide you with the most benefits.

You should choose a slot machine based on simplicity, originality and benefits. If you want a no-nonsense simple slot without any flashing graphics, you should choose a classic slot machine.

If you want to have a chance to win big on a single spin, then pick a progressive jackpot slot.

If you are here to chill out and enjoy a slot machine for entertainment purposes and to enjoy fun bonuses and great graphics, then select a standard video slot.

VIDEO SLOTS

Video slots are the bread and butter of casino slot machines and are the most popular type of slot machine.

They have evolved over time into highly congenial and well-designed forms of casino entertainment. Video slot machines have numerous pay lines and are full of numerous features and mechanics including free spins.

Free spins are the obvious bonus, but do not discount multipliers, wilds and cascading reels, all of which benefit the player and help to create more chances to win. Video slots are perfect slot machines for players who prefer lots of excitement.

CLASSIC SLOTS

Classic slot machines are for players who want to be taken back to a bygone era. These are the type of slots that would litter old style Las Vegas casinos, British pubs and British arcades. 

Classic slots do not offer all the special features that video slots offer, but this does not mean they are boring. There are lots of players who prefer simple machines that give only coin wins.

PROGRESSIVE JACKPOT SLOTS

Progressive jackpot slot machines offer humongous jackpots and periodic bonuses.

Jackpot slot machines allow players to become millionaires from one simple spin of the reels. Some jackpot slots that can pay out millions include Mega Moolah and Mega Fortune.

FREE SPINS AND SLOT MACHINE BONUSES

Sometimes it is possible to grab a free spins bonus on all online slot machines.

Free spins are the most common form of slot machine bonuses. Casinos will offer free spins to their new players, these include free spins with no wagering requirements.

Most often the free spins will come as a part of their welcome package, but sometimes casinos also give out no deposit free spins. The most common slots that they give it on is Starburst, Gonzos Quest, Book of Dead and Aloha Cluster Pays.

If you are a loyal player then a casino will also likely provide you with free spins.

Of course, some free spins are better than others. Always keep track of the bonuses offered by casinos whether you are a registered player or not.

It is much more beneficial to your bankroll if you have access to online casino free spins.
