Ghost Booster! sends Wispy the Ghost drifting across a 5-reel grid with 20 paylines, gathering up coins wherever they land. Landing Coin symbols lets Wispy collect their value, and every so often the collected coins can spin The Wheel of Spooks for an instant bonus prize. Landing a Collector symbol instead sends it into the GO Guaranteed meter, building toward a growing prize floor tied to the upcoming Hold & Spin round. Landing six or more Coin symbols triggers Hold & Spin, where only Coin and Collector symbols can land and every Coin that lands stays locked in place. Players start with a run of respins that resets whenever a new Coin or Collector symbol appears, keeping the feature alive. Collector symbols that land during Hold & Spin gather up the value of every Coin currently on the reels. The feature ends once the respins run out or the grid fills completely, paying out the value of every Coin left in play. With its spooky ghost theme and coin-collecting Hold & Spin action, Ghost Booster! keeps the reels haunted with opportunity.
