Wild Krakatoa is a volcano-themed reel slot from 2 By 2 Gaming. A complete stack of Wild Krakatoa symbols on the third reel opens a sixth reel and awards one or more respins with wild reels held. Its separate bonus begins with three BONUS scatters and awards eight free spins. During those spins the grid has six reels, three rows and thirty paylines, with reels three and four wild. The extra reel is the key distinction from the wild-symbol transformations in Wizard of the Woods.
