If you’re aiming to stretch your bankroll and maximize each spin, targeting high RTP slots is the most effective mathematical strategy. The average return is above-average, but it’s a roller-coaster ride for your bankroll, requiring responsible staking to absorb longer losing runs. Just because a game has an above-average RTP (96%+) doesn’t mean that you’re guaranteed frequent wins, especially if it is programmed to have high volatility.

It’s no use playing at a casino rammed with 97%+ RTP pokies, only to wait three to five business days to get your winnings.
