Based loosely on the famous Wizard of Oz story, this game has a fantasy feel with the setting meant to represent Emerald City. You’ll see A, K, Q and J card suits on the reels – there’s also 3 different potions and a top hat-wearing character. The latter is quite lucrative with 2, 3, 4 or 5 in combination giving you 1, 10, 100 or 500 times your stake. The Book of Oz is both the book and wild symbol – it replaces all symbols.

Book of Oz Lock ‘N Spin comes with a Lock ‘N Spin feature – you can choose to lock up to 4 reels of your choice. Each reel you lock costs a different amount with the total displayed towards the bottom left-hand corner of the reels. This feature is particularly effective if you have 2 Book of Oz wild/scatters and need 1 more to trigger the all-important feature.

That’s known as the Free Spins with 2nd Chance feature – this is played when you get 3, 4 or 5 Book of Oz scatters/wilds. As well as cash prizes of 2, 20 or 200 times your stake, you will receive 10, 12 or 25 free spins. A symbol is randomly chosen to become the special symbol – this symbol expands on each reel to cover the reel entirely. The 2nd Chance element gives you 1 chance to improve the special symbol. Finally, you can retrigger the feature to give you up to 50 free spins in total.

Book of Oz Lock ‘N Spin is more or less the same as the original Book of Oz slot but with the Lock ‘N Spin feature. Both slots are basically Book of Ra Deluxe (by Novomatic) in disguise. Highly volatile, you can win up to 5,000 times your stake on every spin or free spin – the chances increase in the free spins as filling the reels with the high value symbol increases if chosen as the special symbol.
