THEBONUSBUYSLOTS

How individual multipliers combine matters more than their face values. Two 10x symbols on the same win might add to 20x in one game or multiply to 100x in another, and that single rule can change the theoretical ceiling by an order of magnitude. Comparing bonus buy slots with multiplier feature designs therefore begins with finding the word additive or multiplicative in the rules, since the same-looking symbols behave completely differently under each. Multiplicative stacking usually pairs with a lower hit rate to keep the overall return in line.
