A Return Rate of a Game – How Do Slot Machines Pay Out?

Every electronic gaming product has its own parameters, which influence the game process in general and possible rewards in particular. When gamesters deal with Internet slots, the return rate or the percentage of slot machine payouts is crucial for them. It is defined with the help of multiple tests.

Such a rate helps understand how much cash risk takers can get back after many stakes are made in a certain gaming product. The rate is average, so the indicated reward isn’t guaranteed. It’s impossible to say for sure how much cash a punter will win during one session or after 50 sessions played. At the same time, the more spins are made, the higher chances for a prize. In other words, the session results will become closer to the indicated return rate.

Every risk taker would ask, ‘How often do slot machines payout?’ All products are different. And gamesters like high-return electronic products. Compared to other games, the probability of an award is still bigger. What’s more, the luckiest ones can obtain the indicated return with just one large winning.

Key Issues to Define What Slot Machines Payout the Most

Which Online Slots Payout The Most?

An average reward rate for a particular electronic gaming product greatly depends on the developer. The creator adds specific options, mechanics, and specifications to the game, significantly impacting slot machines’ payout percentage. The following aspects are essential when it concerns choosing a good product.


It’s possibly the first and most defining parameter every risk take should pay attention to. It’s that very rate that helps understand the percentage of a possible reward in the long run. The shortening is ‘Return to a Player’, so its essence is relatively easy to understand.

This parameter is defined by means of tests. Thus, 100% is taken for an even-money game, which doesn’t have a house edge (benefit of a gambling establishment). When this benefit is added, the actual rate is defined.

The information about the rate is statistical, so it doesn’t mean a gamester will get the definite sum of stakes back. However, choosing electronic products with a high parameter is wise because the chances are greater with more spins made.

The average RTP of modern gambling products is 96%. Slots with the largest rewards usually offer a high RTP, which is greater than the average. The best online slots payout percentage is closer to 99%. Observe several examples of the highest RTP slots:

Developer RTP, % Title
Yggdrasil Gaming 98 Jokerizer
Felix Gaming 98 Fortune Deck
Quickspin 98.11 Joker Strike
Habanero 98.05 Hot Hot Fruit
BF Games 98.11 Golden Chance
Barcrest 98 Mighty Black Knight
Pragmatic Play 98.1 The Catfather
Barcrest 98 Kings Honour
BF Games 98.08 Best New York Food
Thunderkick 98.6 1429 Uncharted Seas


Another thing that can have a crucial impact on the possible percentage of rewards is a jackpot option. Certain developers offer an occasional chance to obtain a huge prize during every spin. The sum of stakes isn’t usually important here.

There are more advanced online slots with progressive jackpots. Its amount might grow the more stakes are made by various risk-takers. In most cases, such jackpots are characterized by a level system. Thus, gamesters can obtain one of the following jackpots:

  • Mini
  • Minor
  • Major
  • Mega.

Various developers might use other terms. However, the essence is the same. It’s required to remember that when a reward is taken by one of the punters, the prize pool returns to the initial level.

The risks in the highest payout slots machines with such an option are usually higher. Besides, the presence of it might slightly change the reward rate indicated. Besides, some games might require higher stakes to make a risk-taker eligible for the jackpot.

Let’s look at the most advantageous slot machines with the best payouts with such a function:

Developer RTP, % Title
Lightning Box 96.13 Stellar Jackpots with Silver Lion
NetEnt 96.59 Divine Fortune
Spadegaming 96.08 Dragon Gold
Leander Games 97.17 Apollo Slot
Yggdrasil Gaming 94.3 Joker Millions
BetSoft 95.16 Tycoons
Bally 96 Fu Dao Le
RTG 97.5 T-Rex
BetSoft 94.97 Greedy Goblins
Aristocrat 94.85 Buffalo

Largest Win

Various developers create electronic products with different sums of the largest rewards. The latest might be obtained if a certain combo of tokens appears on the screen. In most cases, it impacts an average return rate and might make it slightly lower due to an unexpected opportunity to get a generous prize. Observe several pleasant high payout slots with impressive maximum awards, which can be obtained with a max stake:

Developer Max reward Title
WMS 250,000 US$ Kronos
BF Games 500,000 US$ Golden Chance
Stake Logic 420,000 EUR Diamond Staxx Multipays
IGT 250,000 GBP Wheel of Fortune

Microgaming 480,000 US$ Thunderstruck II

Peter and Sons, in cooperation with Yggdrasil Gaming 500,000 EUR Dragonblox Gigablox
High5 952,000 US$ Thundering Buffalo

Max Stake

The sum of the bet influences the possible amount of reward. However, it can’t influence the odds in most cases. It just means that with bigger stakes, the sum of the prize for a certain combination of tokens will be greater. However, products accepting higher bets usually offer a more pleasant return.

There’s one exception in electronic products with a progressive jackpot. Some of them require making only the largest bets to let a gamester become eligible for a generous reward. It’s connected with a small part of a bet being taken from each punter to increase a prize pool. Consider the best paying slots with the largest stakes accepted:

Developer Max stake Title
Amatic 10,000 Magic Owl
Habanero 6,000 Presto!
Wazdan 10,000 9 Coins Grand Gold Edition
Gamomat 10,000 Ancient Magic
High5 12,000 Twin Win
Genesis Gaming 6,250 Mystic Monkeys
Wazdan 10,000 Burning Sun
Gamomat 5,000 Ancient Riches Red Hot Firepot
Wazdan 10,000 Sizzling Kingdom™: Bison
Playtech 10,000 Age of Egypt

The Issue of House Edge

This parameter differs for various gambling games at Internet gaming facilities. Speaking about the best payout online slots, such electronic products usually offer quite a pleasant house edge. However, it depends on the developer and the peculiarities of the game.

The house edge is connected with RTP and a slot machine payout rate. Thus, the house edge is a statistically calculated advantage of a gambling venue. The parameter might change not only depending on the product and its developer but also depending on the bet made. Generally, the house edge is the average percentage of a gamester’s stake that a gambling club will keep. For instance, if an RTP is 97.5%, the house edge is 2.5%.


Another thing that is vital to understand is the probability of awards and the general riskiness of an electronic product. This characteristic helps determine how frequently a jackpot might be paid and how large the possible rewards are. The following levels of variance are distinguished:

  • Low (products offer regular winnings with small amounts)
  • Medium (products proffer quite frequent rewards, which might be both small and high)
  • High (the best slot machine payouts are not frequent but are huge when happening).

High-volatility online slots are usually the most generous. However, they are quite risky.

Where To Search for Products with the Largest Rewards?

Choosing a trusted and reputable facility to enjoy electronic products with the most generous prizes is important. Here are a few recommendations for choosing the best payout online casinos:

  • Observe the presence of operating permission (approvals of fairness from independent organizations will be a plus)
  • Look at the set of products and make certain there’re big payback slots
  • Read about bounties and their conditions
  • Check that there’re comfortable banking tools
  • Observe the quality of customer assistance.

It’s possible to find the lists and reviews on the online casinos with the highest slot payouts on independent websites (such as SlotsUp).

Recommendations to Select Products with the Largest Rewards

Which Online Slots Payout The Most?
  1. Prefer high RTP casino slot machines characterized by medium/high variance.
  2. Try a demo product first – there are many free slots to play and train.
  3. Opt for products offering progressive jackpots.
  4. Pay attention to the largest award possible in a particular game.
  5. Be careful with a developer’s choice–some offer low-RTP products.
  6. Avoid products with numerous complicated options: they usually lower the reward probability.

What Do Loose Products Mean?

All electronic products are divided by gamesters into tight and loose. The first category presupposes smaller RTPs and less frequent awards. The second category means larger prizes and more frequent winnings.

Thus, the looser a product is, the more it is beneficial for risk-takers.
