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.

Understanding RTP Percentages

When we take an RTP of 100% for instance, 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. Chances are always very minimal 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.

You, the player have the chance for bigger wins with a less than 100% RTP but the casino will over time make some profit across all the players participating in the video slot.

Therefore, the higher RTP percentage of a slot game, the better it is for you the player. Lower RTP percentages are always expected in land based casinos but it is always best to play online games that offer RTP percentages of 90% and above.

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

How is the 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 digg in the list with the 10 highest rtp slot games.
