How We Rank High RTP Slots

When our team assesses and ranks high RTP slots, we look for the following:

High RTP

First and foremost, our aim is to bring you an up-to-date selection of the highest RTP slots we encounter at online casinos. To do this, we comb each platform, looking for reel spinners that provide above-average RTP. So, generally speaking, that’s any slot that provides above 96.0% RTP.

Maximum Payout

Playing a slot with a provenly high RTP is one thing, but if the maximum payout is low, it’s unlikely to hold your attention for very long. Hence, we also factor in the maximum payouts when ranking high RTP slots. In a situation where two slots have the same/very similar RTP, we may choose to rank one higher than the other based on its winning potential.

Software & Developer

When we review high RTP slots, we also factor in the developer. Reputable developers ensure fair gameplay by incorporating random number generators (RNGs) and hold licenses from respected gaming authorities. Most will also ensure that the games are independently tested and provably fair, meaning you will win approximately as specified by the RTP if luck is on your side.

Availability

Finally, chasing the holy grail of a 99.9% RTP slot is all well and good, but if you can’t locate the game at any trusted online casinos, the chase is futile. To counter this, we prefer to rank and review slots that are easily accessible at a wide range of online casino platforms, detailing precisely where you can find them in our tables and reviews.

What Is RTP?

RTP is a theoretical Return To Player figure. In short, if you played the game for an unlimited number of spins, this value indicates the money you’d receive back in prizes.

So, for instance, let’s say the game in question has a particularly high RTP of 99%. For every $100 you feed into the game, your actual return will be $99, with the game keeping just $1.

How RTP & Slot Payouts Work

Don’t forget, however, that the RTP value is purely a theoretical number. Since every single spin is random, there’s no way to determine how much you can win or lose in a short session. The Return To Player only calculates the value over an infinite time frame.

The way a casino slot pays out is greatly affected by its volatility. Imagine two theoretical games, Slot A and Slot B. The former is highly volatile, while the latter is extremely low in volatility. But both have an RTP of 99%. Let’s imagine spinning the reels of each 10 times, for $1 per play.

With Slot A, you might win a single payout of $9 from those ten spins, with no other prizes paid at all. For Slot B, your results would likely be more spread out, with lots of frequent payouts that are smaller in size. A dollar here and there, perhaps $2 if you’re lucky, but still adding up to $9.

As you can see, the overall payout is the same, but the frequency at which prizes are awarded varies. This is slot volatility.
