A machine that has a 95 percent RTP, for instance, should eventually return $95 for every $100 wagered. However, since this number is based on thousands or millionrummgolds of spins, individual experiences may differ significantly. Slot machine volatility, or the risk involved in playing a specific game, is another thing that players should be aware of. While low-volatility slots typically yield smaller wins more frequently, high-volatility slots may offer larger payouts but less frequently.
