I believe that Lucky Ox, Wild Pinata, and Regal Riches are the best fit in the category of favourite low volatility slot machines. Along with this, I’d like to add that volatility greatly affects your returns when playing slots. I found a helpful explanation about this on Gamblizard, which clarified how volatility impacts gameplay. For example, games with low volatility tend to pay out smaller amounts more frequently. Whereas slots with high volatility have the potential for bigger payouts, but these wins occur less often.
