What are RTP’s?

You may be familiar with the workings of a slot game but you may not have heard of the term “return to player payout percentages” before, so you may be wondering what exactly they are and how they affect the way in which any slot game works and operates.

All online slot games are random and a random number generator is used to determine the result out each spin, the logic behind this is relatively simple, each reel position and reel symbol has a number attached to it and dependent on which series of numbers the random number generator generates when you click on the spin button this will determine to outcome of that spin.

One some reels there will be more than one of the same reel symbol and as such the slots payouts are structured around the odds of you lining up a winning combination of any matching set of reel symbols.

If there is just one particular reel symbol on each reel, as is often the case with jackpot symbols, then this winning combination will be much harder to hit than one with several symbols on each reel.

Any slot game designer will design a matrix of all of the reel positions and the symbols along with the odds of those combinations being spun in and they can then give the slot its expected return to player payout percentage or RTP as it is known.

This figure will be presented as a percentage, and will be the amount that the slot game is expected to return to players over the long term operation of the game. So if a game has a published RTP of say 96%, then for every £100.00 fed into the game and played will see the slot paying out to players, over the long term £96.00 resulting in a £4.00 profit for the operator of that slot per £100 wagered..

However it should be noted that the payout percentage is based on the long term operation of that slot game, so you will not be guaranteed to get £96.00 paid back if you play £100.00 worth of spins!

Your actual return to player payout percentage per session is going to fluctuate wildly which is why playing slots is so exciting, you can have winning sessions and losing sessions, however the longer you play any one particular slot game the nearer to its expected RTP you will find yourself getting.
