What makes a top slot site?

With so many slot sites available, it’s useful to know what you’re looking for when you want the best slot site experience. These are some of the things that you need to consider:

• Easy deposit and withdrawal methods
• A large range of different games
• Slot bonuses
• Fantastic customer support
• A website that is easy to use and navigate
• A great mobile app

The best online slot sites make it easy for you to deposit and play, and just as importantly, to withdraw your winnings. With various payment options available, there is bound to be one that meets your needs.

These slot sites have an ever-growing range of games for you to play. Easy to navigate, these sites ensure that you can find your favourite games in no time at all. Complemented by an equally user-friendly mobile app, you have the freedom to play online slots wherever you may be.

How to play slots

Once you find the best online slot sites, you then need to sign up and register an account. Once you’ve done this and deposited any funds, you can then go on and play. Although online slot sites can vary, in general, this is what you will need to do:

1. Choose, and then open the game you want to play
2. Read the instructions, understanding what you need to win
3. Choose the level of your stake and then spin

The best online slots have clear information, letting you know what each symbol means in the game and about any potential bonus features.

Most slot sites also provide an auto spin option. This means that the spins will continue until you either stop these yourself or you run out of funds.

Types of slots

The best online slot sites have such a wide range of games available to play but broadly speaking, these are broken down into 5 types:

• Classic 3 reel slots
• 5 and 7 reel slots
• Progressive jackpot slots
• Megaways slots
• Mobile slots

Classic 3 reel slots are simple to play and resemble the game machines that you would find in land-based casinos. Generally, these tend to have 3 reels and 5 pay lines. You match the symbols across the lines to win.

5 and 7 reel slots are an extension of the classic 3 reel slots with an increase in the number of possible pay lines.

Progressive jackpot slots work by adding a small amount of money to the jackpot every time a player doesn’t win. The moment that a player does win, the jackpot resets and, the build-up starts again.

Megaway slots contain a random reel modifier that adds an increased number of symbols to a reel when it appears. This increases the number of ways a player can win.

Mobile slots are designed for specifically playing on mobile devices such as tablets and mobile phones. These are optimised for smaller screens and allow players easy access to enjoy online slots.

Real money vs free play

The best online slot sites even allow you to try out the most popular slots for free. In ‘free play’ mode, players are given virtual coins or tokens to play with. These have no cash value, meaning winnings have no cash value either, but they allow you to try out some of the best slots, risk-free.

Free play mode is an ideal way to find which games suit you best. It gives the chance to experiment and get to understand how each game works before risking real money.

Playing with real money, you can play the same games that you experienced in free play mode. The difference is that, as you are playing with your own funds, any winnings are now real and can be withdrawn.

New slots

Adding new slots regularly keeps players interested and coming back for more. The best online slot sites know this so, that is why you’ll always find new ways to be entertained.

The classic 3 reel slots are fun and engaging to play but when new slots emerge, they tend to have more pay lines, free spins, and bonus rounds. These all add to the excitement and offer new ways of winning.

Playing slots on mobile

Not so long ago, if you wanted to play any online slots, you were tied to your laptop or desktop. Mobile apps came along as an added extra for some slots sites. These are now an expected feature for the best online slot sites. Some of the mobile online slot games you can expect to see are:

• Classic 3 reel
• 5 reel slots
Progressive jackpots
• Megaways slots

Slot bonuses

The best online slot sites have much to offer in the way of bonuses and rewards. We’ve laid out details of casino bonuses and what they mean here, but here’s an overview of what you can expect:

• Welcome bonus
No deposit bonus
• Free spins
• Cashback
• Reloads
• VIP bonuses

Slot bonuses are often subject to wagering requirements. Simply play through the requirements before you withdraw any winnings. If you’re not sure what a wagering requirement is, it relates to the number of times you must play through a bonus before you can withdraw any winnings.

FAQs

Which slots have the highest RTP?

Return to player (RTP) is a measure of the percentage of stakes a game returns to players (generally over a minimum of one million plays) and is an accepted guide to how a game will perform. The best online slots come with high RTPs such as:

  • Mega Joker – 99% RTP
  • Rainbow Riches Pick ‘n’ Mix – 98% RTP
  • Ooh Aah Dracula – 99% RTP
  • Jackpot 6000 – 98.6% RTP
  • The Catfather – 98.1% RTP

Do all online casinos offer slots?

No. While the majority of online casinos offer the best online slots, others have their focus on table games such as Blackjack.

Which providers are most popular?

We talk more about popular slot providers here but the most popular are:

Are online slot machines rigged?

No. With Return to Player (RTP) preset, there is no need to rig online slots. The casino already knows where the RTP is 95%, that they will be earning 5%. Add to this the value of the online gambling industry as a whole; no online casino would risk rigging games and losing their valuable customers.

Is there a slot strategy to improve chances of winning? 

There’s no universal playing strategy to game the online slot sites. But that’s all part of the fun. You’ll need to discover your own rhythm and your own style of play. We’d recommend settling on a type of online slots that suits you – choose between video and classic slots, with different jackpot formats. And, most importantly, always enjoy your betting, sensibly and in moderation. 

Where can I find low/no wagering slot bonuses? 

Lots of places. The no-wager bonus is one of the most common giveaways of slot sites. The best online slots providers will usually have a particularly tempting offering – think something along the lines of 100 free spins plus a cash bonus that matches your initial deposit up to a certain amount. 

Are no deposit slot bonuses too good to be true?

Nope – you can score no deposit slot bonuses for all sorts of reasons, most commonly being a new customer at various slot sites. They’ll let you have a set number of free rolls without having to spend a single cent. The winnings are all real and the thrill is the same. You’ll just need to hit the wagering limit (the amount you need to bet after receiving a bonus) before you can cash out your spoils.
