Book of Oz slot review (MicroGaming)

Book of Oz is a video slot by Microgaming that can best be described as “Book of Ra with a twist”

Book of Ra is about the most copied slot machine ever: the number of Book of Ra-like slots must now run into a hundred.

Book of Dead, Book of Gods, Book of Aztec and Book of Oz, are all variations on the brilliant Book of Ra slot.

Triple Edge Studios. the provider behind Book of Oz develops online slots for Microgaming exclusively.

In any case, it is sometimes nice to deviate from the standard Egyptian mythology/adventure theme.

Book of Oz was mainly inspired by the famous fairytale film Wizard of Oz. But there is more: they also have a respin feature built-in, where players can pay to hold reels or respin a reel.

This provides an entirely new approach to the game: you have to put on your strategy hat.

How does the Book of Oz slot machine work?

Book of Oz has 10 paylines, which are divided over 5 reels with 3 rows of symbols.

Betting is possible from $€ 0.10 per spin up to $€ 25 per spin.

Variance and payout rate

The maximum reward is 5,000 x your total bet, allowing you to win $€ 125,000 when betting to the max.

The variance of Book of Oz is high: this is a slot machine for the serious player who is not afraid to take some risk.

The theoretical payout rate is excellent: 96.31%.

Symbols and payouts

The highest paying symbol is the wizard with a green hat. This will give you 500 x the bet for a 5-of-a-kind on an active payline. That is considerable.

The other premium symbols also yield a lot: 3 magic potions are worth between 75 x and 200 x the total bet for a 5-of-a-kind.

The low symbols consist of the card symbols 10, J, Q, K and A. These are worth the same between 10 x and 15 x the total bet for 5.

The Oz book symbol is wild and replaces all other symbols. Also, this symbol acts as a scatter.

Free spins bonus

3, 4, or 5 books give you the free spins bonus: you get 10, 12 or 25 free spins, respectively.

You know the drill: you get a special bonus symbol that works as a scatter during the free spins and covers the entire roll. This way, you always get all 10 paylines in a winning combination.

It is possible to retrigger the free spins.

Respin feature

During the primary game, it is possible to use the respin feature. This means that you can respin 1 of the 5 reels, at a surcharge. This comes in handy when you want to activate the bonus game or have a 4-of-a-kind of a high symbol with an empty position in the middle.

Beware: respins are not cheap, and there is no guarantee that they will bring you extra rewards. If you change bets in between, respins are no longer possible too, so take that into account.

What is our verdict on Book of Oz?

Microgaming has finally released a decent online slot with Book of Oz, although the theme is far from original.

The respin feature gives the game a new dimension, and that is always fun to experience.

The Book of Oz has a huge payout potential: it is possible to win up to 5,000 x your bet during the free spins and that every spin!

3.8 stars out of 5.
