Don’t worry we’re not going to write in depth about each area, we’ll just give you a quick overview to help share our expertise with you.

But first let’s take a look at the different types of slots you can play.

What are the Different Slot Types?

A good starting point is understanding what the different types of online slot games are. These are the categories of slots and every online slot game will fall into –

Each type differs slightly from the previous one, but in the majority of cases these days, slots are increasingly resembling one another. In fact, you will see that nearly all video slots now contain some 3D elements and vice versa, which make the experience more interactive and ultimately rewarding.

Online Slots have Different Jackpot Types

Jackpots are another beast altogether, and they are a very loved segment of the slot experience. In general, there are two main types of jackpot games:

  • Fixed Slots
  • Progressive Slots

The fixed jackpot game is capped at a specific, pre-determined amount whereas the progressive jackpot is continually growing until it’s won at which point the counter resets. The progressive jackpot is pooled across multiple independent casinos – both online and land based.

How do Online Slots Work?

Online slots allow you to digitally spin the reels like a slot machine in a casino with the aim of matching the symbols from left to right (or vice versa depending on the game) in order to win money.

Inside each online slot machine there is a Random Number Generator (RNG) which is configured to pay out a certain percentage and keep a percentage for the house, typically you are likely to win around 95% of the time.

Every slot game comes with a pay table which determines which symbols you will need to get in a row along with their corresponding prize which ultimate produce the payout that you get should those symbols land.

The slot games featured by Slots and Tables will typically have 5 reels and 3 rows, although online casinos are always coming up with new ideas and games and you can sometimes see 10 reels or more.

Winnings will usually be awarded when you get the same symbols in a line for 2 or 3 rows, with the biggest prizes for hitting all 5 rows.

Every type of slot game comes with variances which is how often you are likely to win. With higher variances, you are likely to win more often, but smaller amounts. So, with lower variances, you are likely to win less, but win bigger amounts.

Of course, bigger jackpots are reserved for hitting the combinations that are less likely to come up.

Slots don’t really come with instructions, there is very little to learn. You can simply just hit that spin button, watch those reels turn and see if you’ve won by matching symbols.

Online Slot Symbols – The Basics

Every slot game is unique in its own way and will include game features that add excitement and energy to the game you are playing. This can include things like bonus rounds, multipliers, free spins and other bonuses. Sometimes the more lines you hit, the more game features are unlocked. Using these features effectively can help you make the most of your winnings. We explain some of these game features below.


Wilds are a type of plain symbol that can substitute and replace any other symbols to help you make up a combination or line. For example, if you have four black jacks on a line of 5 and need another one to win, if there is a wild symbol, this can be used to complete your line. Some wilds can make up a whole reel, while some wilds will also have a multiplier so if you win, the earnings will be doubled or tripled.


A scatter symbol is a specific symbol on the slot game in additional to things like aces and queens, and if you land 3 or more, it will typically unlock more game features. There can be multiple scatters on the screen at any given time and getting them all in a row can sometimes deliver the biggest jackpot. Scatters will usually be clearly marked and have a unique design depending on the slot game. They are sometimes known as a player’s best friend.


This allows you to multiply your winners by 2, 3 or more. It is a type of bonus which is usually given when you have unlocked other features or won other stages, but it allows you earn more as a result.

Best Online Slot Payouts

A great way to check out whether you want to play a particular slot game is to see what the Return to Player (RTP) rates are. Normally, the majority of slots will be offering over 95% of the money you have wagered back to you.  This is what RTP means, the amount returned back to you in winnings.

How does a Slot Machine Payout?

Let’s explain this a little better. Online slot game makers estimate that for any amount you wager, $100 for the sake of this example, you will get at least 95% back. However, this percentage can vary in the short term. In fact, you will need to play over a thousand spins to get this exact percentage.

The good news is that in the short to mid-term, these variations can help you win bigger sums of money. Again, this is only in theory, as it’s purely based on luck and you won’t find a working strategy to help tilt the numbers in your favour.

Conversely, you can benefit from the fact that a lot of developers are pushing the RTPs of their online slot games to almost 97% nowadays, so you will be able to find even better slots to improve your chances of winning.

Choosing High Payout Slots

If you are looking for the best online slots to try and turn a profit, you can do this, but just remember everything boils down to luck. Still, that doesn’t mean you should stick to one slot game because you like the graphics.

You can choose multiple criteria to pick your game. For example, if you are looking for a big payout and low volatility, Starburst is an excellent pick. The title has 96.09% in RTP and it offers low volatility, meaning frequent payouts. Here are some other high rtp slots which are very popular and usually rank amongst the best online slots.

• Dragon Shard – 96.77%
• Breakaway – 96.42%
• Gonzo’s Quest – 95.97%
• Jack and the Bean Stalk – 96.30%

Other slot makers, including Microgaming, have good titles to offer, too. For example, Immortal Romance offers 96.86%, which puts it well above the industry average and therefore a game that you will want to play.
