What Are Online Slots & How To Play

If you’re a fan of bingo games but have never delved into the world of online slots before, then it may be time to take that leap.

Online slots promise endless amounts of fun and come in all manner of themes and variants, with the aim of the game fairly similar to bingo - match the symbols to win prizes. The more you match, the bigger the prize!

To land a winning combination players are required to place a wager on each payline before spinning the reels. The winning symbols on the slot must then line up along one of the predetermined paylines for you to win.

Each symbol offers a different sized payout, with paytables within each game highlighting the exact amounts and all the winning combinations.

As well as standard symbols you will also find a series of wild and scatter symbols which act as bonuses. If you land these bonus features you will likely trigger bonus rounds which can greatly enhance your winnings, so make sure you read the game information before you spin.

Slots bonus rounds are often regarded as the holy grail for many online casino fans because they can offer payouts in the hundreds of thousands of pounds, or even millions if you’re playing a slot with a progressive jackpot!

Choosing The Best Online Slot Game

All of the best online casino sites offer online slots and there are always a number of things to look out for before you decide which one to play.

Among the key things to take note of include:


Don’t just pick any old slot to play, there are a huge selection of themed slots on the market from Ancient Egypt-inspired classics like Cleopatra to games influenced by hit TV shows such as the popular Narcos slot.

If you have a particular interest or hobby, then it’s incredibly likely there will be a slot out there that’s perfectly suited to your interests!

Return To Player (RTP)

One of the most important things to note when choosing a slot game is the return to player figure, also known as RTP. This is essentially a percentage and it tells you how much you are likely to win over the course of playing a specific title.

Most slots have an RTP percentage of between 95% and 99%, with the higher the RTP, effectively the higher chance you have of winning.

That’s because RTP is the percentage that an online slot will pay out over its lifetime, compared to the amount that’s paid in.

Of course, it isn’t that straight forward. Random Number Generators mean the game is completely random so you have as much chance of winning big on one spin as you do the next. It’s also worth noting that you could actually win much more than that 96% RTP but equally you may win nothing at all.

Ultimately though, the higher the RTP the more chance you have of receiving a sizable payout over time.

Slot Bonuses

It’s always worth looking out for the slots that have the most bonus rounds or features. Not only can these provide a more entertaining game, but features such as wilds and scatters can provide free spins and multipliers, which can significantly increase your winnings.

Slot Volatility

Alongside RTP you should also be aware of slot volatility, or variance. This is another good signifier of what your chance of winning is.

Volatility is split into three categories:

  • High
  • Medium
  • Low

Low volatility slots will offer more frequent wins but at a lower payout, whereas the risk is higher in high volatility slots but payouts are bigger.

Medium volatility slots are, as you can probably guess, a mixture between the two.

Types of Slots Available To Play

Across online slot sites and here at Moon Bingo as well as themes and variance, you’ll also find a number of different types of slot, that pay out in different ways.

When it comes to landing winning combinations, there are two main types of slot, these being payline and cluster slots.

Payline slots are the more commonly found, with you spinning the reels and if a series of symbols land on a predefined payline then you win. Cluster slots are slightly different and they require the symbols to cluster with each other to win, with the higher the number of symbols in a cluster, the more you will win.

Both are equally as fun to play, but it is always worth checking each slot so you know how you will potentially win.
