The Slot Payout Concept

What is a slot machine's payout? Simple! The payout ensures that a percentage of the proceeds is converted into player prizes or winnings.

The player who wants to maximize slot machine winnings must consider the particular slot machine’s payout percentage to understand which slots are the most advantageous in terms of winning opportunities.


So, as a first step, let's consider that land-based slot machines have an average 75% slot machine payout, while the payout of online slot machines averages between 90% and 99% (yes, playing slots online is much cheaper!).

The main point to clarify here is that “payout” refers to the value of winnings allowed per slot cycle - pre-defined inside a microchip - versus the total amount collected by the house.

Put more simply: an ordinary slot machine always retains a percentage of all proceeds!

Instead, the remainder is returned to players in the form of winnings.

Before this happens, the slot must complete a full game cycle. At the end of each cycle, the slot will return a certain payout, represented by a percentage known as the “Return To Player” (RTP).

The Slot Cycle

The slot machine cycle is another concept that must be clarified to fully understand the dynamics of winning on slots.

To understand how often slots should pay out, the number of spins (also known as hands or rounds) in each game cycle must be evaluated.

We can define this cycle as the number of spins required for the slot to return the set payout.

For example, if the slot has been set to end its cycle with 40,000 spins, the machine will have to pay out the winnings within this time frame.

Once a cycle is finished, a new one starts automatically, subject to the percentages mentioned above.

The RTP Percentage

As already briefly discussed earlier, RTP means "Return To Player" and it’s the average payout percentage we have talked about so far. As you can imagine, in general, checking the RTP can be a smart move to understand which slot games have a good chance of awarding wins.

Slots with the Highest RTP

Below, we would like to point out a few slots that have made a name for themselves by having a very high RTP on average. Despite what has been said so far, we always want to remind our readers that winning online slots is always based on luck.

💡 Did you know? Variables such as RTP are undoubtedly useful but are not a determining factor in winning. So always remember that RTP is calculated over the long term, over millions and millions of spins, and that it is still a variable average based on the cycles of a slot. Each slot is constructed differently, and there is no exact way to predict if, when and how much it will pay. This means that if a slot has an RTP of 97%, we should certainly not expect it to pay out $97 immediately for every $100 spent in our session. However, a high RTP is always a good indicator, if you plan to find a slot game to your liking. You might also look out for bonus features, check slot volatility as well as payline mechanics.
