What is Slot Games RTP?

Slot Games RTP is the acronym for ‘Return to Player’ and it is always displayed as a percentage. This term basically implies how often a player is likely to win, therefore, the higher the percentage, the higher the chances of winning.

what is RTP

So how do we know that the Return to Player is fair for all slot games? 

Well the Gambling Commission is making sure all the involved parties stick to the rules and all the suppliers and manufacturers of slot games are licensed and fully checked.

According to the UK Gambling Commission

The operator making gaming machines available for use, as well as the gaming machine suppliers and manufacturers, must be licensed by the Gambling Commission, or hold a permit issued by a local licensing authority.

Also the UK Gambling Commission is making it clear that Gaming machines must make information available about their category, % RTP and whether they are compensated or random

Understanding RTP Percentages

Now let’s have a look at the slots RTP meaning in more detail

When we take an RTP of 100%, it means that the probability of a player winning the game is equal to that of the house. If the RTP gets over 100% it is an implication that over time, the casino is losing money on the game.

There is no chance that there will be a slot game RTP of over 100% because there won’t be any reason for the casino to offer the game in the first place.

For example if a slot game has an RTP of 97%, then for every £100 wagered on this games from all players collectively £97 will be returned as winnings.

The slot games are programmed to average this RTP on the long term. So even if the return is slightly lower or slightly higher short term this will average out to the RTP of the game sooner or later

This is where one of our slot tips ( take the money and run) comes into practice as well!

This is why Best Payout Slots matter

The higher RTP percentage of a slot game, the better it is for the player.

Lower RTP percentages are always expected in land based casinos. Hence, it is always best to play online games that offer RTP percentages of 94% and above.

Under no circumstance should you settle for something less than this simply because there is much competition and choice in online casinos. You can find and play the highest payout slot machines quite easy.

How is RTP Calculated?

The following formula is used to calculate the RTP on a video slot machine:(Total amount returned to players) / (total amount bet by players) = RTP

Note: The reason as to why a slot will never have an RTP of 100% is because this will most likely put the house out of business as they will make enormous losses.

Still, your chances as the player to make gains are high when the RTP is closer to 100% in the long term. So let’s dig in the list with the 10 highest rtp slot games.
