Purchasable Bonus Enhancements
Big Fish Casino’s Buffalo Gold Stampede Anniversary Edition is the first time we’ve seen a machine let players use app-wide currency to buy enhancements for a bonus. At the start of free spins, players can buy three tiers of chests that grant three random enhancements. With chests that cost $5–$25 worth of currency and produce over 50 unique combinations of enhancements, this mechanic has the potential to be a major revenue driver if introduced across multiple machines.
Although disrupting gameplay to offer purchases before each free spin bonus is potentially risky, Big Fish Casino reduces this risk by introducing the mechanic on a popular, previously released machine. Using a machine that players are familiar with makes the purchasable enhancements feel like an added value rather than a normal bonus that players need to pay for.
