Choose by Volatility
If your budget is limited, go for low-volatility games — your bankroll will last longer. Wild Bandito (PG Soft, maximum RTP 96.73%) and Lucky Neko (PG Soft, maximum RTP 96.73%) are options like this. If you are aiming for bigger wins, choose a high-volatility game, but keep in mind you will need a larger budget for that.
