What is RTP and Why Does It Matter?

RTP stands for Return to Player. It’s the percentage of all wagered money a slot game will pay back to players over an extended period.

Slots with a higher RTP are more attractive because they offer players a better chance of winning back their wagers, making gameplay more rewarding. For example, a slot with a 99% RTP returns more money to players compared to a slot with only 95% RTP.

Choosing slots with a high RTP means your bankroll can potentially last longer, giving you more opportunities to win big. That’s why smart players always check the RTP before selecting a game.
