Legacy of Oz is a follow-up ‘Book of’ mechanic slot and it plays out on 5 reels with 10 paylines.I t started with Book of Oz, then Sisters of Oz, now the L. Frank Baum’s classic story returns to the theme Legacy of Oz Hyperspins. The legendary ‘book of’ free spins round has received a couple of enhancements, some common, others more original. Legacy of Oz Hyperspins might not be a hotbed of innovation, yet it has enough of a novelty factor to entertain players into this style.
