Book of Oz is a 5 reel game that is 3 symbols high. There are 10 paylines in total, playing from left to right.
The Book of Oz – The “Book of Oz” is the game’s wild symbol, replacing all symbols other symbols. It is also a scatter symbol and it triggers the Free Spins feature.

Free Spins – To trigger the Free Spins feature you need to reveal 3 or more of the “Book of Oz” symbols on either a single spin, or with the inclusion of re-spins. 3 “Book of Oz” symbols will award you 10 free spins and 1 coin. 4 “Book of Oz” symbols will award you 12 free spins and 10 coins. 5 “Book of Oz” symbols will award you 25 free spins and 100 coins.

Book of Oz is an excellent looking game, brought to us by Microgaming. We all know the story and we all the know the colours that are associated with it. Needless to say there is a lot emerald green in this game and a certain wizard appears to play a very important part in it. Whilst the game looks good, I don’t believe that the theme has been properly exploited. There is only the one interesting symbol, acting as a wild, a scatter and a free spins trigger. The only features are the free spins, the re-spins and the expanding symbols within the free spins. I couldn’t comment on this game without taking a look at the re-spin feature. More and more often we are seeing in-game or in-spin betting with slots games that allows you cut straight to what you might call the good stuff. To do so you need to pay and obviously you except the risk and reward to increase as you do so. It is vitally important you pay attention to the re-spin bet and ensure that you are playing within your parameters, as it is very easy to think you are betting a limited amount only to fail to see that pot of gold disappear very quickly. Playing the re-spin does put the odds more in your favour, but remember, you are still playing at a disadvantage and the stakes do become dramatically raised. All things considered, this is a solid game, offering limited features and a re-spin feature that you need to keep an eye on.
