Book of Oz is a 5 reel, 10 payline slot from Microgaming that can be played, on all devices of course, from 10p to £25 per spin. You are taken to the mysterious Land of Oz where emerald riches await! It comes with a Respins feature where you can respin a reel as many times as you want to win. There’s also a Free Spins feature where up to 25 free spins can be won (initially) – a random symbol expands to hopefully give you wins of up to 5,000 times your stake!

Based on the Wizard of Oz story, Book of Oz has a fantasy theme and is set within Emerald City. With cartoon style graphics, symbols on the reels include A, K, Q, J and 10 playing cards as well as keys, hearts, books and wizards. The book is both the scatter and wild so replaces all symbols.

When it comes to bonus features, it comes with a Respins feature – you can basically respin a reel as many times as you wish (at a cost) in order to complete winning combinations or trigger the Free Spins feature more easily.

You can also gain access to the Free Spins feature by getting 3, 4 or 5 book scatters anywhere in view – this will reward you with 10, 12 or 25 free spins respectively. Furthermore, 3 or more scatters during a free spin will retrigger the feature – with no limits, you can benefit from unlimited free spins. More importantly, 1 symbol (bar the wild) is randomly selected to become the expanding symbol – this chosen symbol will cover the entire reel to give you bigger wins basically.

High variance, Book of Oz is an entertaining slot with simple bonus features really – it can though reward you with payouts of up to 5,000 times your stake on every free spin with the high-paying expanding symbols! Let’s just hope your luck is in and the magic of the Book of Oz will leave you spellbound. If you like the theme, WMS’ Wizard of Oz Ruby Slippers is both a land-based and online favourite.
