Book of Oz Features

Containing free spins, expanding symbols and re-spins, Book of Oz has everything you need except a multiplier feature. It’s worth noting that the re-spins are paid. Not only that but they appear just in the base game and only wins involving the re-spin are paid out to the player.

Book of Oz - Free Spins

Free Spins

Managing to land 3 or more book scatter symbols will trigger the free spins round. Rolling 3 will gain you 10, 4 will give you 12 and 5 will give you 25 free spins! Free spins can also be retriggered!

Book of Oz - Expanding Symbols

Expanding Symbols

At the start of free spins, the special symbol is randomly awarded. It expands to cover the reels and pays on matching symbols land anywhere on the line. You can win up to 5,000x your bet during this mode.

Book of Oz - Re-Spins


You can re-spin at the end of each base spin and choose to re-spin as many times as you like. If you are close to completing a win, you can re-spin one reel at a time. The only downside is that this comes at a varying cost in the game.

Book of Oz Review

Become entranced by the magical world of Oz. Developed by Triple Edge Studios and published by Microgaming, Book of Oz is a 5-reel, 10 payline slot that is inspired by the Wizard of Oz book series written by L. Frank Baum.

Granted the slot doesn’t have the variety and creativity of features found in other magical slots such as Dr Fortuno, but manages to deliver with most of the ones needed for an online modern slot.


As the slot begins, you’ll notice that the background is surrounded by beautiful décor. Taken straight from the books themselves, you are in Emerald city and in the Wizard’s palace. It completely oozes decadence and grace in the background to completely transport you to the enchanting land of Oz.

Sounds and music played through the slot has an ethereal quality to it with steady beats and harp sounds. At times it can be serene and calming, whilst other times it can sound intense.


Despite being based on a fantastical book series - the gameplay is simple. All buttons and menus are featured at the bottom of the screen. The bottom left button leads you to settings, gameplay and features in game you need any of that.

It’s easy to see the spin button as it’s enclosed within a green bubble to make it stand out. Betting and autoplay are next to the spin button with players being able to set between 10 to 100 autospins.

Win Potential

Features such as free spins and re-spins improve the win potential greatly. Especially considering that re-spins have an increased RTP at 96.50% during this mode. The only downside is that you have to pay for re-spins in this game.

In the base game, the RTP is at a great 96.31% which is way above the average. The maximum payout is available through expanding symbols during free spins. If you manage to fill up the reels with the wizard symbol, then you can win up to 5,000x your stake. During the base game, you can win up to 250x your stake if you roll 5 wizards.

Our Verdict

Book of Oz could’ve been a landmark within magical themed slots, but sadly doesn’t fully deliver. The cost of using re-spins lets it down a lot. Not only this, but there are no multipliers on this game. Design wise it’s incredible, win potential is decent and the gameplay is pretty fun - but the features aren’t fully there. That’s not to say that Book of Oz isn’t a great game, but it falls short of being brilliant.
