What Is A Payout Percentage, And How To Check It?

Simply put, the payout percentage of a casino or a particular slot machine is the amount of cash that it would take over a certain time frame before it starts paying it back to the player with gifts and prizes won. The best payout casino online percentage is tested and confirmed by independent authorities such as eCogra in a way that they use the slot more than a million times to figure out the highest payout casino percentage of a particular slot. So, in essence, a slot machine that has a 90% payout on a million spins doesn’t mean that it’ll have the same if you do just 1000 spins.

Below you will find a review of top paying casinos and highest RTP online slots!

What Payout Percentage Is Considered High?

Usually, the highest payout online casino percentage can be up to 99%, while the lowest is around 75%. 99% is considered to be an extremely high number and probably the highest recorded one out of all casino games. The highest payout casino games are usually around the highest number, although some vary and go lower to around 98% while others have a 98.6% best payout casino UK percentage.

In theory that is exactly what it means. The higher the payout percentage, the more cash will be returned to the player over time, for example, if the payout percentage is 99% of a machine and you’ve spent over $1000 on that same machine over some period of time, the winnings you’ll get from the slot would equal $999.

How Does A Person Check The RTP Of The Best Payout Online Casinos And Top Paying Casino Slots?

Return to Player or RTP is the measure of how much a slot machine can pay back to its players for each unit wagered over time. The difference between 100% and the RTP on the slot machine itself is known as the house edge. The best way to figure out the RTP of an online slot game is to visit the official casino or a slot developer website where that information is listed.

Can You Gamble Online Legally Within The UK?

When it comes to the UK, gambling is completely legal, although it has some specific guidelines that need to be followed. There are laws which are designed to control the gambling scene as a whole and regulate the industry in order to make it safer for gamblers to make bets online.

You need to be 18 or more years old in order to gamble legally, be it both online or real-world. The online casinos which offer gambling as a service are legally obligated to confirm that their customers are at least 18 years old.

Does the UK Gambling Website Require A License To Operate?

If an online casino decides to provide a platform for remote gambling, which can be done online or through other means, and advertise this platform to customers that live in the UK, you will need a license from the Gambling Commission.

When It Comes To Online Slots, Are They Rigged, And What Is RNG?

Online slots are not rigged, especially if they are licensed and published by a recognized body. The software developers behind each of the online casino slots have to go through tests and regular inspections that ensure that all of their games are based on RNG, and are in no way rigged.

RNG is short for a random number generator. Instead of a person physically shuffling, the process is done through a mathematical formula which ensures that every card that is dealt, dice that is rolled, or wheel which is spun, is completely random and unpredictable.
