What is RTP?

If gaming is new to you, then you’ll be forgiven for being entirely bemused by the amount of jargon and abbreviations used. Often a VLT, that’s a video lottery terminal, by the way, has an RTP percentage detailed after it. So, yes. What is RTP, you might ask? And you should! This is possibly the key statistic you need to know before playing. RTP stands for Return To Player which now makes it quite an easy figure to understand. If the RTP is 90%, for every £1 bet, 90 pence will be returned to the player. And the house will keep 10 pence. Simples!

Obviously the house always wins right? And let’s face it, the house needs to win something for their efforts in hosting and creating the game. But they don’t need a fortune. Online casinos have far lower overheads than bricks and mortar casinos and their outlay is only the creation of the game, and hosting the game on a website. So you should be looking for an RTP that is as high as possible. Some games have an RTP that is as high as 99%. Look for the highest rate you can find. The next thing you need to know about is volatility.

What is volatility?

So you’ve found two slots with great RTPs of 99%. But there’s another figure you need to consider, and this is the volatility. In mathematical probability the term is also referred to as variance or dispersion. But in slots, you’ll most likely here the same value called HIT FREQUENCY. So let’s consider the two games you have found, both with an RTP of 99%, one has a hit frequency of 25% and the other has a hit frequency of 2%. Which of these is the best slots payout? 

On the face of it, it seems that the first machine is the better of the two. Its variance is 25% so it will payout one in four times it is played. So great you’ll win every four games, more or less. But you will only win back slightly less than you put in. It won’t be paying out huge amounts. Every one in four games you’ll roughly get your stake back. So the game that started of sounding a lot of fun, with you winning lots, could in fact, get quite boring. Now let’s consider the second slot we found. Now it had a dispersion of just 2%, a much less enticing percentage. This means that every one hundred games it will pay out twice, or once every fifty games. But this means that it will pay out big when it does payout. Every fifty games, it will pay out 99% of what was put in.

Big or Small Payouts?

So, if someone was playing before you in the random video lottery terminal, and got bored or ran out of cash after forty games without a payout, you could come along and play a few games and grab a win of roughly fifty stakes. So should you go for big or small payouts? And where is the slot volatility displayed?

Volatility is a little more confusing and mysterious but let’s explain simply: A slot with a low volatility has a low risk of losing your money and pays out more often. And a slot with a high volatility has a higher risk of you losing money. It pays out less often and is represented by a lower percentage of hit frequency. Unlike the RTP, that virtual online casinos MUST display, volatility is a different matter.

Which is best low or high volatility?

The only way to find out about volatility is to play the game. If you start off slow and just play ten slots or so, you’ll get a feel of the game. Is it paying out already and full of animations, cool spins and features? This game is low risk and still lots of fun. It will still be coded so that a big win is possible but it will be rare and most of the payouts will be relatively small. Over a period of time, it is possible to win. With a game that has a high volatility you’ll find yourself spinning and not winning. Some people like this kind of game and are in it for that eventual BIG PAYOUT, but some find them boring and risky as you could play for a long time with no payout. The choice is yours. We hope you got the basics down of slot statistics in this easy-to-read guide.
