Why Do You Look For The Slots With The Highest RTP?

What RTP tells you is how much of all the money that is put into a slot machine will come back to players as wins over time. But it doesn’t mean that every lesson will go exactly as planned.

If you play a slot machine with a 97% RTP, 97 cents of every dollar you put into it will be paid back to you over time as wins. However, that doesn’t mean you’ll get 97 cents of every dollar you put into the machine.

Still, it makes sense to play slots with better RTP. More RTP means that everyone has a better chance to win or at least lose less.
