Book of Oz from Triple Edge Studios: Slot Review - an enchanted land of Free Spins awaits!

This latest release from up-and-coming software developer Triple Edge Studios and software giants Microgaming invites players to walk the yellow brick road and visit the magical realm of Oz where a powerful wizard runs the whole show. Inspired by the famous fantasy novels created by author L. Frank Baum in the early 1900s, this slot depicts the wizard of Oz as a dapper looking gentleman sporting a stylish emerald coloured top hat! The author wrote 14 full-length Oz books in total with the most famous book of all being ’The Wonderful Wizard of Oz’ which was later adapted into a blockbuster Hollywood movie. Join us as we head to the Emerald City to see what enchanted riches await us on the reels?

Book of Oz is a 5 reel slot with 10 paylines that comes with Expanding Symbols, Free Spins, and Respins.

Special Features

The first feature to highlight is the Wild symbol which is represented by an image of a book. Like most Wilds, this symbol replaces all other symbols to help form winning combinations on the reels. Unusually, it also acts as the Scatter symbol too and pays out in any position.

At the conclusion of each base spin, you can choose to Respin a reel as many times as you like to further increase your chances of completing a win, A word of warning here as each Respin is charged at a cost and only wins involving respun reels are paid out.

The Free Spins bonus round is triggered by landing 3 or more Scatters anywhere on the reels. The more Scatters you land then the more Free Spins you will be awarded. For example, 3 awards 10 Free Spins, 4 gives 12 Free Spins, and 5 Scatters awards a fine set of 25 Free Spins. At the start of Free Spins, one symbol will be chosen at random (apart from the Wild) which will proceed to expand to cover the entire reel and pay out when matching symbols land anywhere on a line. Manage to get a full screen of expanding symbols then you will nab yourself a huge cash prize on the reels. This feature can also be retriggered by landing 3 or more Scatters in any position. There is no limit as to how many times you retrigger Free Spins which in theory can lead to unlimited Free Spins.

Theme, Graphics and Sound

The presentation of the game is visually stunning as it takes place deep inside the Emerald City of Oz with tall marble green columns and beautifully designed glass windows. Symbols are nicely polished and consist of the Wizard, a Lion Potion, a Heart Potion, a Key Potion, along with your typical A – 10 icons. The animations are smooth as symbols move up and down the reels rapidly and are highlighted by a magical green glow when part of a winning combination. It is particularly satisfying when you expand symbols in the Free Spins feature as they are surrounded by a neat yellowish globe effect when expanding.

The music features an atmospheric and enchanting soundtrack. It complements the fantasy theme of the game perfectly.

Win lines, Payouts and Jackpots

The game features 10 paylines, a solid RTP of 96.31%, and a superb maximum payout worth 5,000X your initial wager.

Our Verdict on Book of Oz

This slot is made by Triple Edge Studios and published by Microgaming and is by far the best creation to come from their partnership since the release of the smash-hit slot Wicked Tales: Dark Red. Book of Oz features amazing graphics, a fitting soundtrack, and excellent bonus features. Paying to respin reels is a novel feature and something that could be incorporated into future games as it allows you to make strategic decisions the more you play. The standout attraction of this slot is the Free Spins feature which is quite tricky to trigger but worth investing some time in as if you land a full screen of Wizard symbols here then you will win the top prize of 5,000X your wager! When it comes to variance, I found this slot to be High so make sure to have plenty of bankroll on hand before playing this game.

A city full of emerald riches is yours for the taking when you open the Book of Oz!
