When choosing real money slots, one of the most important factors to consider is the Return to Player (RTP) percentage. RTP represents the theoretical percentage of total wagered money that a slot machine will pay back to players over time.
For example, a slot with a 96% RTP means that, on average, for every £100 wagered, the game returns £96 to players. While this doesn’t guarantee individual results, it helps players choose games with better payout potential.
What Makes a Slot High RTP?
A high RTP slot typically has an RTP of 95% or higher, giving players a better return over time compared to lower RTP slots. These games often attract experienced players who understand the value of optimising their bankroll by playing slots that offer the best chances of long-term winnings.
Are High RTP Slots Always the Best Choice?
While RTP is crucial, it’s not the only factor that affects gameplay. Volatility (variance) also plays a role. Low-volatility slots pay out smaller but more frequent wins. High-volatility slots have larger payouts but occur less frequently. The best approach is to find a balance between RTP, volatility, and features that suit your playing style.
