RTP in one sentence
RTP (return to player) is the share of bets a slot pays back over millions of spins. A 96% RTP means €96 returned for every €100 wagered on average, over the very long run, not in your session.
Volatility
Low volatility: small, frequent wins. High volatility: rarer but bigger wins. Pick according to your budget and patience.
