Understanding RTP
RTP, expressed as a percentage, represents the average amount a slot returns to players over time. For example, a slot with a 96% RTP theoretically returns £96 for every £100 wagered. Key points about RTP include:
- Higher RTP = Better Expected Returns: Games with higher percentages give more frequent and larger returns over time.
- Influenced by Volatility: High RTP combined with low volatility offers frequent smaller wins, while high RTP and high volatility may deliver bigger, less frequent payouts.
- Site-Wide Selection Matters: The average RTP across a site’s game library is a good indicator of value for players.
Focusing on high-RTP sites maximizes long-term play potential and winning chances.
