What Is The Payout Percentage?

Knowing a slot's payout percentage is important for slot players, yet regrettably, many beginners often misunderstand it. Misunderstanding the payout percentage can leave novices disappointed with their slot machine experience. So, we will attempt to define the payout percentage in this piece.

Key Concepts Around Casino Payout Percentages

The casino payout percentage represents the amount of money you win on wagers you place over a predetermined period of time. This percentage for slots refers to the amount you will ultimately win based on the time and money you invest.

Based on the way the slot machine manufacturer set up the game and on local legislation, casinos can change the payout percentage of a game. The majority of slot machines will be pre-set with a payout range of 85–95 percent.

A casino may raise its payout percentage in order to draw in more customers. For instance, some older casinos that compete with the newer, fancier casinos typically have a greater payback.

One slot machine might have a 90% payout percentage; for instance, if it receives €1 million in "Coin In" and pays out €900,000 in "Coin Out" (10% of the winnings go to the casino as profit). This is modeled mathematically as the likelihood of what might happen. Beyond slots, every casino game has an associated payout percentage, which is an indication of what could be the approximate payout for a certain bet value.


If you have any knowledge of how slot machines work, you probably already know that Random Number Generation (RNG) is key to how they operate.

  • RNG controls the results of each spin of the reels in a slot machine, but it is also a technique that guarantees fairness
  • The randomness of outcome is a fundamental need across any game that thrives on random results. 
  • Operators and providers are forbidden from offering games that don’t abide by the RNG algorithms to ensure an unbiased winning possibility.


Percentage Return To Player can be thought of as the portion of the deposit that is returned to the player in the form of prizes such as jackpots, max wins, and multipliers. 

Depending on the category, different reward amounts are offered by gaming machines. The RTP is an average that was reached over a sizable number of game sessions, not just one game. 

Depending on the type, the average % RTP has often been calculated over 10,000 or 100,000 random gameplay sessions, associated with a particular game.

House Edge

That the casino has a built-in edge over its games shouldn't come as a surprise. Casinos win over players because the odds are mathematically against them. 

The house edge is the name given to this inherent advantage that casinos enjoy over players. In terms of numbers, it represents the portion of each player's wager that the casino keeps over time as profit. 

For instance, the house edge in roulette is around 5%. Thus, the casino typically keeps 5 cents of every dollar wagered as profit and pays out the remaining 95 cents to players as prizes.

How to Find Slots with Higher Payout Percent?

Examine the payout ratios of several casinos. You can frequently obtain this information on a casino's website or in industry reports, and many of the casinos with the fastest payouts make their payout percentages public knowledge. 

A casino with a high payout ratio might only provide a few games, whereas a casino with a lower payout percentage might have a larger selection. Finding a new casino with a nice mix of high payout rates and a large selection of games is crucial. 

For example, certain slot machines from reputed providers could offer mammoth multipliers such as 100,000X and promise a Max Win of €10,000,000, yet the RTP is as low as 85% and house-edge is high as 15%. Meaning the probability of grabbing that Max Win really low and the casino would deduct a substantial percentage of your earnings.

How Does Payout Percent Help in Big Wins?

For various reasons, picking slots with large payouts is an intelligent move. First off, when you win at a slot machine with a large payoff, you get more value for your money. 

Some games also provide strategies that make winning even simpler. While some players may opt for casual sessions, where interesting themes and thrilling gameplay take precedence. 

While some serious players, with an appetite for a larger investment, may choose games that offer higher RTP.


The payout percentage actually is a statistic that informs them of when a machine should pay out. So, it might be challenging for Irish players to determine a slot's payout percentage. To generate the payout level of a slot machine, it costs a lot of money and time to spin the reel hundreds of thousands of times.

The most aspect to keep in mind is that, as a player, making a few spins on a slot machine is essentially immaterial to the payout percentage. The investment, wagering needs, and winning amounts are usually nominal. It would become increasingly important to the player as they make higher deposits and expect higher cashflows.

Always choose a credible licensed casino in Ireland, where games are regularly audited. Casinos that offer reputed payment integrations and transparent withdrawal policies with clear wagering needs.
