Slot machines used to be exceedingly simple, with only three reels and one pay-line, there wasn’t really much else to them. In fact, the very first examples didn’t even have instantly available prizes, instead, gamblers would have to go to the bar and claim a free drink or cigar. Oh, how times have changed, eh? These days you can win well over 10 million dollars, sometimes from just one spin – check out these UK online slots!

And that’s not the only thing that has got more complex about slots over the years, far from it! It was the emergence of online slots that really changed things, as developers found it necessary to incorporate some more complex things in order to make full use of the online platform. Two things – RTP and RNGs – are now widespread in the industry, but what exactly do they mean? Let’s find out…

RTP: What Is It?

So, first things first, what exactly is RTP? Well, RTP stands for Return To Player and is something that didn’t really exist properly before the introduction of regulations such as The Gambling Act 2005 in the UK. In essence, the RTP is a percentage that reflects the average amount that a player will get back from their wager.

In the UK at least every developer is legally obliged to give this statistic, something that makes the industry a lot more transparent and therefore appealing to new players. So, there you have it – RTP stands for Return To Player, and will be a reliable indicator of how well you might fare on a particular title.

RTP: How Can It Benefit You?

As you could imagine, this knowledge can be incredibly beneficial for online slot gamblers, in particular, because it can help you choose the right slot to play from the outset. Most experts will tell you that an RTP that exceeds 96% represents a pretty good one, whereas anything below 94% should be avoided. Although, it is also important to consider the fact that progressive jackpot slots will naturally have pretty awful RTPs, however, the chance to win many millions of dollars should make up for it.

RNG: What Is It?

Now then, what on earth is an RNG? You may be asking. We don’t blame anyone for not knowing, but RNGs are actually the most important thing for online slots ever. The reason why? Well, put simply if it were not for the RNG online slots simply would not exist, as it is this that influences where the reels land on any given spin.

RNG stands for Random Number Generator, and it basically does exactly what it says on the tin – generates a random stream of numbers. These values can then be used to make sure that the reels are spinning randomly. If it were not for the invention of the RNG slot games would still be purely mechanical beasts, and they, therefore, would not be able to be played online at all. So thank your lucky stars the RNG was created!
