There’s a green tinge to the visuals in Book of Oz which are very nicely constructed. Joining the royal values are an assortment of higher value potion symbols and the Wizard of Oz himself. The Wizard’s Book of Spells symbol acts as both the wild and the scatter.
After each spin, you’ll be given the opportunity to spin another reel again. The price varies on each reel depending on how the likely it is to create an improved combination – this is known the Respins feature.
Land 3, 4 or 5 of the Book of Spells symbol and you’ll trigger the Free Spins feature - on offer here are 10, 12 or 25 free spins. Boosting your winning chances are expanding symbols which fill the reel whenever they hit. These symbols are chosen at random. Landing 3, 4 or 5 scatters results in a retrigger and another round of free spins with no limits.
This is a very classy take on this Wizard of Oz spin off. The visuals are very nicely done and the gameplay offers plenty of variety. It’s a volatile game too. You can expect lengthy spells when your bankroll will seemingly fly off to Kansas. Get lucky with the expanding symbols in the free spins round and the coins can quickly build - awards of up to 5,000 times your stake can be won on each free spin.
The Wizard of Oz has been a popular source of inspiration for slot game developers. Book of Oz is one of the better adaptations. With its high spec visuals and quality extras, it’s an impressive all-round performer. If you like super high variance slot games, then you should enjoy this trip to Emerald City. I also recommend you try the official Wizard of Oz slot games from WMS with Wizard of Oz Ruby Slippers the best one.
