Understanding RTP and Volatility
Knowing these two fundamentals before you play makes it easier to choose the right game.
What is RTP?
RTP, or Return to Player, is the theoretical percentage of total bets that a slot game returns to players over the long term. It is not a guarantee — every spin is completely independent and RNG-based.
High-RTP games may return more over the long term, but results can vary in the short term.
What is Volatility?
Volatility refers to the frequency and size of wins. Low-volatility games pay out smaller prizes more often — useful for preserving your balance.
High-volatility games win less frequently, but the prizes are larger when they do. Choose based on your budget and playing style.
