Book of Oz Slot Review: Discover RTP and Key Mechanics

Published on Microgaming collaboration platform, and launched on 12 December 2018, the Book of Oz game comes with 10 paylines, 5 reels, and 3 rows including an RTP of 96.31%. The Re-spins feature that has an RTP of 96.5% makes this game unique – you get a chance to spin single reels as many times to create winning combos.

Book of Oz free spins and bonus

The Free Spins feature is triggered when you land on three, four, or five Book Scatters on the reels concurrently. This gives you ten, twelve, or a twenty-five Free Spins respectively. The feature can also be re-triggered by landing at least 3 Scatters on one Free Spin. In this feature, 1 symbol is selected randomly to function as the expanding symbol. It then covers one or more reels to boost your winning chances.

The main bonus feature available here is the Free Spins bonus. When you land 3 or more golden book symbols, you will be in a position to trigger up to 25 Free Spins. A special symbol during this round is selection and expands whenever it appears to cover an entire reel. An impressive 5000x prize is available thanks to this feature. It is, therefore, important to maximise on these few bonus features.

Book of Oz theme and symbols

This is a fun online slot with low-value symbols represented by 10, A, K, Q, and J card suit symbols, while hearts, keys, wizards, and books represent the premiums. The book is a combined Wild and Scatter and replaces all symbols. Although the potential in the slot is concentrated on the Free Spins, the game offers great value. For instance, you will win 500x your stake when you land 5 wizards on a payline.

The Book of Oz is a straightforward old-school slot at its core with an interesting Re-spin feature. In any spin, you are allowed to spin individual reels as many times in an attempt to land winning combinations. This comes in handy if you happen to be a symbol away from a 500x wins. Avoid re-spinning those reels frantically, as the cost of Re-spins is decided depending on the potential.

RTP and volatility

Book of Oz is equipped with a simple slot-game mechanic and a feature of Free Spins that can be easily re-triggered. This is quite high up on the volatility scale. When you land a full screen of expanding symbols, the top cash prize is 5000x your stake. The slot here evokes an emotional manual dexterity since it’s a theme that perfectly resonates with players. The return to player is quite welcoming.

On the Book of Oz, the RTP is 96.31% on regular spins as well as in the base game. During the Re-spins, the RTP could increase to 96.6%. Either way, the RTP never sticks all that much from the industry’s average of 96%. It is always wise to adjust your bets to a level that your bankroll can handle, as this is a highly volatile game.

How to play Book of Oz

Being a 10-payline, 5-reel online slot from Microgaming, this game is easy to play. Choose your bet in the bottom left-hand side of the screen. There are several options you can choose from. Your coin size can be adjusted between 0.5 and 0.01, and you can bet up to 5 coins, making the maximum bet €25 and minimum bet €0.25. This is a good range for both penny slots players and high rollers.

For you to hit winning combinations at Book of Oz, you must land three or more symbols matching on the same payline. The man symbol that awards a prize worth 500x your stake is the top prize available. This, and other picture symbols offer up prizes for just ‘2-of-a-kind’ wins, meaning that you will be in a position to cash in on payouts more frequently as you continue playing the game.

Slotsia’s review

Book of Oz brings something unique to the “book slot” genre. The unlimited single reels Re-spins, Free Spins with expanding symbols, and high potential of up to 5,000x. However, the max-bet level is a bit low, and it’s only meant for “book” genre lovers. The Book of Oz is certainly one of the best releases on this platform. With volatility and potential being high, any fan of the “book” genre ought to check out on this.
