Risk profile and Risk control
Acquiring a bonus round packs all the risk into a single moment. The feature’s result decides your return on a significantly bigger bet than a normal spin would cost. The theoretical return stays put, but the actual variance can swing wildly. You could purchase ten bonuses in a row and drop money on every single one, or you could secure a max win on your first try. That binary nature requires a structured session plan. Figure out how many feature buys you’re willing to stomach before you start, and stick from that limit no matter what happens in the short term.
