When it comes to playing an online slot machine, the first thing that must be considered is its Return to Player or RTP. As its name suggests, this acronym means the rate of all the wagered money that will return to a player over time.

Let’s give an example: there is a slot game with an RTP of 98%. So, every £1 you wager, you will get back 98p. Nonetheless, it is not as simple as it seems because it requires more than one million spins. If you want to understand more, luckily for you, all of your questions about RTP will be answered through this article.

However, always keep in mind that it depends on your long period of play. So you should be realistic to hope that you will really win back more than 90% of all your bets. Regrettably, the mobile slots offer less than 94% RTP and gambling on any games under this amount is like throwing money out the window.
