Can Casinos Adjust Slot Machine Payouts?

Can Casinos Adjust Slot Machine Payouts?

Slot machines have always been a staple in casinos, both online and in-person. But, even though they have been around for a while now, many casino enthusiasts often wonder if casinos can alter the potential payouts on slot machines. 

In this article, we will delve into this topic and discuss the common misconceptions surrounding the payout system of casinos. 

Can Casinos Change Slot Machine Payouts?

Casinos do not have the capability to manipulate the odds on slot machines at any time. However, when they choose slot games to have either on physical machines or on online casino sites, they can choose from a range of payout rate options offered by the developers. 

Casinos cannot change it themselves at any time, as they are regulated by strict laws and regulations, and doing so would create an unfair advantage. 

In the UK, all legitimate online and land-based casinos are regulated by the UK Gambling Commission (UKGC). This regulatory body ensures that casinos do not alter the odds on their slot machines to create an unfair advantage. Slot machines are checked regularly to verify that their Return to Player (RTP) percentages are as stated and that their Random Number Generator (RNG) is functioning fairly. 

Reputable casinos that are found manipulating their slot machines could face severe penalties, including hefty fines and potential revocation of their operating licence. Hence, while technically possible, the risk associated with tampering with slot machine payouts significantly outweighs any potential gain for reputable casinos. 

Do Online Casinos Change the RTP?

Return to Player (RTP) is a theoretical term in the slot world that refers to the average amount of money a slot machine pays back out to players over a long period. 

The RTP of a slot machine is decided by the game provider, not by the casino. Top-notch game developers like Microgaming, NetEnt, and Pragmatic Play decide the RTP of their slot machines based on various factors like the cost of development and the expected popularity of the game. 

As mentioned earlier, casinos can choose which of the available RTP options to go with, but they cannot then change it themselves. 

Casinos must adhere to the RTP range set by the game developer. Therefore, while one online casino may list the RTP as 94.0%, another may list it as 95.5%. 

Do Casinos Adjust Odds Depending on Day, Time or Holidays?

Contrary to popular belief, casinos do not adjust slot machine payouts based on the day of the week, time of day, or even the holiday season. The RTP set by the game developer remains constant, regardless of how busy or quiet the slot machine is. 

It's a common misconception that casinos pay out more during the holidays or on specific days of the week. However, the reality is that the RTP of a slot machine remains the same whether it's Christmas, summer, a weekday, or a weekend. 

If the odds changed depending on the time, then this would not be fair to the players, as two different players could play the same slot machine at different times and have different chances of landing a win. To avoid this, the Random Number Generators (RNG) that determine the outcomes of slot machines do not take external factors such as the time or date into account when generating outcomes. 

So, no matter when you choose to play a specific slot game, the odds of winning are the same on every spin. 

Are Slot Machines Manipulated By Casinos?

Online casinos do not manipulate slot machines. As stated above, the outcome of each spin is determined by a Random Number Generator (RNG). This RNG uses a computer algorithm that generates millions of random number sequences per second, making the outcome of each spin completely random and fair. 

The RNG operates independently of the casino and cannot be manipulated in any way. This ensures that every player has an equal and fair chance of winning when playing a given slot game. 


Despite common misconceptions, casinos do not adjust slot machine payouts or odds based on the day of the week, time of day, or even the holiday season. The RTP is determined by the developer and selected by the casino but cannot be altered on a whim. The RNG determines the outcome of slot games, and the casino cannot manipulate its function in any way. If they were to do so, they would likely end up with their licence to operate being revoked. 

So, no matter when you choose to play a slot game, the odds of winning are the same on every spin. They only vary between different slot games, and the casino does not have a hand in them. 

Remember, the primary purpose of playing slots should be for entertainment, not to make money. Please gamble responsibly, set a budget and stick to it, and never chase your losses.
