2. How online slots work
Online slots run on a Random Number Generator (RNG). Every spin is independent - the result does not depend on what came before.
RTP (Return to Player)
RTP shows how much a slot game theoretically returns to players. A 96% RTP means that for every €100 wagered, an average of €96 is returned.
Examples: Starburst RTP 96.09%, Book of Dead RTP 96.21%
Volatility
Volatility determines how often and how large the wins a slot offers. Low volatility = frequent small wins. High volatility = rare large wins.
Low: Starburst · Medium: Book of Dead · High: Dead or Alive 2
RNG (Random Number Generator)
EMTA-licensed casinos use RNGs tested by independent authorities. The outcome of each spin is completely random and unpredictable.
Paylines
Paylines determine how symbols must align to form a win. Megaways slots have up to 117,649 paylines on every spin.
