Some online slots developers include an option called feature buy (a.k.a. bonus buy). This option lets you pay a certain amount of your stake to automatically trigger the bonus. A game might, for example, require you to pay 100x your stake. Assuming you’re wagering $1, you’ll need to bet $100 to pgplaygaming automatically launch the bonus. Feature buy seems like a handy option to use if you don’t like waiting on the bonus to trigger naturally. However, it can wreak havoc on your bankroll when you don’t win much from the feature. Perhaps you’ll consider using this option once in a while at low stakes. I definitely don’t recommend using bonus buy very often or even at all.
