The Book symbol still does everything – it’s both Wild and Scatter, and once the bonus triggers it picks one symbol to expand across the reels, paying even on non‑adjacent hits. The difference is that, with 99% RTP under the hood, those familiar dry spells and full‑screen dream moments are happening in a game that gives back far more of what you put in over time.
