Understanding Volatility
Low volatility: Frequent small wins. Suitable if you want to hold your bankroll and play for a longer time. Fortune Gems (JILI) and Lucky Neko (PG Soft) are examples of this type.
High volatility: Wins come less often, but when they do the amounts are larger. Wanted Dead or a Wild (Hacksaw Gaming) and Fire in the Hole xBomb (Nolimit City) are high volatility slots.
What Is RTP Used For?
RTP (Return to Player) is the theoretical calculation of how much a game returns on average over the long term. For example, Fortune Mouse (PG Soft) has a maximum RTP of 96.96% and Mahjong King (CQ9 Gaming) has a maximum RTP of 97.20%. However, RTP is not a guarantee — every spin is independent.
