Book of Oz was developed by one of the biggest casino software companies in the world, Microgaming. The 5 reels and 10 pay lines configuration has been seen many times before, but this slot has something unique. The re-spin feature allows you to re-spin any reel of your choosing, in hopes for a bigger combination or even a bonus round.
Book of Oz Gameplay
The slot has a similar look and feel to other Microgaming games, who are pretty consistent with their design. When you play slots online, you expect great graphics and gameplay, as well as the chance of a decent win, and Book of Oz delivers on all of this. One thing that sets it apart is the re-spin functionality, which we cover in more detail in the next section.
The Re-Spin Feature
The re-spin feature on Book of Oz is what sets it aside from other Microgaming games. You will be offered a price to re-spin individual reels, and the better the position it is in, the higher the price. For example, if you only need 1 more bonus symbol, a re-spin would cost more. It can start at as little as 0.1p and increases depending on your stake.
The Bonus Round
As with all the best Microgaming slots, the aim is to reach the bonus round. The Book of Oz bonus features 10 free spins and an expanding symbol that is selected at random when the feature starts. The higher value symbols can result in huge bonus wins. If you land 3 more bonus symbols during the feature, you will win 10 more spins to enjoy, and this can happen more than once.
