Book of Oz Pros & Cons

  • 💥 Expanding symbols in free spins game
  • 🤑 Good jackpot potential
  • 💫 Free spins feature
  • 😭 No bonus round
  • 👎 Relatively low maximum bet


Microgaming's Book of Oz slot machine has an incredible and magical atmosphere. Play across ten different paylines across the game's five reels, arranged in three rows. One can spin the reels with a single payline activated, or they can wager on all ten paylines for the best possible chance at winning. This game is accessible to players of varying financial means and betting preferences due to its wide betting range (from €0.10 to €25 per spin). 

The developers of Book of Oz have put a lot of time and effort into the game's visuals, making the final product look fantastic. The screen's entire backdrop, from the dazzling emerald pillars to the ornate green glass behind the reels, has been meticulously crafted to fit the theme. The same can be said of the symbols, all exquisite works of art with thoughtful layouts and enticing colour schemes.

The best games usually have a curated score, and Book of Oz is no exception. The sounds of the Emerald City play as the reels spin. In addition, certain functions have their corresponding sound effects. This adds a new dimension to the game and makes it much more interesting.


This is one of several slot machines, including one by Microgaming, that draws inspiration from The Wizard of Oz. The five-reel, 10-payline slot machine Book of Oz transports players to the centre of the Emerald City.

Book of Oz is a slot game with a Wizard of Oz theme that may or may not be what you expect. In this version, Dorothy and Toto are conspicuously absent from the reels. Those elixirs of love and bravery are the only things mentioned in the story that has anything to do with the Lion or the Tin Man. Not a sign of a twister or the Good Witch of the West to be found. We promise that "Somewhere Over the Rainbow" won't play in the background.

One reason is that Book of Oz is not a "branded slot" from Microgaming. It's not a remake of the 1939 film The Wizard of Oz. Instead, it's based on Frank L. Baum's canon of Oz novels (14 total). Because of this, the book serves as the game's scatter icon.

When you're on the go, pick up a copy of Book of Oz and have a blast. It has been optimised for various mobile devices, and its compact design and stunning visuals make it ideal for playing on mobile gadgets of all shapes and sizes. Book of Oz is available on your mobile device via many of the best online casinos in the world. There are no differences in features or quality between the desktop and mobile versions of the game. If you try it on your mobile device, you'll be able to take your experiences in Emerald City wherever you go.

Symbols and Payouts

The standard A, K, Q, J, and 10-card suit symbols make up the low-value symbols, while the more unique keys, hearts, books, and wizards make up the premiums and give the game its unique flavour. As you might guess, the book acts as both a scatter and a wild, meaning it can substitute for any other symbol. While the free spins feature is where most of the action is, the main game still has its merits. When five wizards appear on an active payline, the player is awarded 500 times their wager.

It's essentially a simple classic slot machine with a unique Respin feature. After a spin, you can re-spin any of the reels to increase your chances of getting a winning combination. This can be helpful if you're missing the third book or are one symbol away from a 500x win in the main game but need that symbol badly. However, the costs of the respins are determined by chance, so you shouldn't keep spinning the reels too quickly.

RTP & Volatility

Book of Oz has a relatively high return-to-player percentage of 96.5% compared to other video slots. This, along with the game's medium volatility, makes it ideal for players who want consistent payouts and are also open to the chance of larger, unpredictable payouts occasionally. If this sounds appealing, you should try your luck at other games that offer a similar return to player percentages. Both Gemix and Genie Jackpots Megaways have payout percentages of over 96%.

How to Play

The Book of Oz slot machine has ten always active paylines. Bet one coin per line or up to five if you choose. It is possible to alter the wager by changing the value of each currency. As there are twenty-five paylines, the maximum bet is €100, or five €2 coins. The maximum bet in some online casinos featuring the Book of Oz is only €25 because the maximum coin value is only €0.50. Once you've set your wager, you can either manually spin the reels or use the autoplay feature to let the game do the work.

Book of Oz Bonuses

Single Reel Re-Spins

The Book of Oz slot machine's single-reel re-spin feature is one of its most exciting aspects. Here's how it goes down. A re-spin button will appear at the base of each reel after a winning spin. When you put your mouse pointer over the re-spin button, the cost to spin that reel again will be displayed.

Since you can keep re-spinning until you get the winning symbol, using the re-spin feature is a foolproof way to ensure a win. This promotional video for Microgaming's Book of Oz slot machine features single reel re-spins. However, you should know that these new iterations won't come cheap. The cost of a re-spin is proportional to the number of possible additional possible prizes. For instance, if you're one Wizard symbol away from a payout, the re-spin cost will be higher than if you were one Jack symbol away from a payout. Your entire bankroll can quickly disappear if you are not careful and keep buying re-spins. That's money out of your pocket that couldn't be used for gambling on Book of Oz or anything else.

Free Spins Feature

Free spins are available in the Book of Oz slot machine, in addition to a re-spin feature that can be activated on a single reel. When three or more Book of Oz scatter symbols appear anywhere on the reels, the player is awarded several free games. You'll be awarded a certain number of bonus spins depending on how many scatter symbols show up.

  • Three scatters = ten free spins

  • Four scatters = 12 free spins

  • Five scatters = 25 free spins

You can get more free games, and scatter symbols show up more often during the bonus round. Thus, your chances of regaining access to the bonus spin round are raised. Your free games will not begin until the book stops on a random symbol. This symbol will cover an entire reel during the subsequent free matches. Expanding symbols can spread across the whole reel to boost your winning potential.

Your winnings can pile up quickly if the randomly expanding symbol is a higher-paying icon. You can still win big if you get enough of a low-paying symbol on the reels. The expanding symbols during the free spins bonus round are a welcome extra. The Book of Oz's most exciting bonus feature is, by far, the re-spins of a single reel. You can maximise the benefits of both bonus features by using the re-spin feature to initiate the free spins. That is the most profitable strategy for playing the Book of Oz slot machine.

There are ten paylines available on the Book of Oz title, which uses a conventional five-reel setup.

Highest payout

You can wager as little as 10 pence per spin up to €25 at the maximum. Again, high-stakes players may feel this is below average compared to other Microgaming slots. However, the maximum possible payout during the free spins bonus round is 5,000x. So, a €25 wager could eventually turn into a €12,500 jackpot. The main Book of Oz character has a base game payout of 250x for a five-of-a-kind win. If you play all ten paylines and hit a full screen of symbols, you'll win 2,500 times your bet in the base game.

Our Verdict

The Book of Oz slot machine by Microgaming is fun to play because of its vibrant graphics, unique bonus features, and compelling story. Players looking for a high-potential, low-stakes slot game will love this one, but high-rollers should look elsewhere. This game features a generous free spin round and allows players to wager on up to 10 paylines. Book of Oz is a fantastic mobile game because it features high-quality visuals and fast-paced gameplay that players can enjoy on their smartphones or tablets. If you're intrigued and want to discover more, follow that yellow brick road and try The Wizard of Oz.
