Microgaming have been inspired by the classic story, The Wizard of Oz, for this slot, Book of Oz. Set in the Land of Oz, but with an interface that takes quite a leap of faith to get to what most of us believe it might look like. A nice respins feature sits in place to tempt you, respin any reel as many times as you like to complete combinations and win big.
Presented over a 5 x 3 format, as per usual, with a modest 10 paylines included, the slot makes up for the flimsy structure by adding a game-changing unlimited free spins feature offering up to 25 initial spins that may continue indefinitely: one symbol becomes an expander, giving you the potential for up to 5000x-your-stake wins on each and every spin. Wow.
Playable across devices this offering from Microgaming comes set against a marble background, with cartoon-like symbols. A tenuous fantasy theme set within the Emerald City. A range of high value symbols relate to the theme, such as keys, hearts, books and wizards, with the lower value symbols in the form of playing card icons, including A, K, Q, J and 10. The book is both the scatter and the wild, replacing all symbols.
Bonuses and features
Free respins are one of the trump cards here, allowing you to respin a reel as many times as you like to get those winning combos - and into the free spins feature. You will pay for this feature, but it does come in pretty handy, and harks back to the hold features on the old pub fruit machines.
Getting three to five book scatters anywhere across the reels will also get you into the lucrative free spins feature, rewarding 10, 12 or 25 free spins respectively. Three or more scatters will retrigger the feature if they appear during said free spins, and this is where the limits are lifted and potentially infinite spins lie. One symbol will randomly be selected to become an expander, covering the whole reel and boosting the overall winning power; this doesn’t happen with the wild though.
There’s no doubt that Book of Oz is an entertaining slot, with its high variance and relatively simple bonus features. It's also got the potential to pay out up to 5000x your stake per spin with those expanding symbols we mentioned, and this is big news! So, rub your lucky whatever, and get playing!
