Slots review Triple Edge Studios Book of Oz

Book of Oz Introduction

At last, a title that feels like a real standout from the Microgaming production line—or more accurately, from its partner studio Triple Edge Studios. Book of Oz is a familiar book slot at heart, but it brings a small twist. You get everything you’d normally expect from the genre, except for the Respin feature, which lets you re-spin individual reels as many times as you want to try to complete winning combinations—for a price, of course. As with the classic originals, you can also expect a bonus that retriggers often and comes with plenty of upside.

Book of Oz is a 5-reel slot with 10 paylines built in html5, so it runs smoothly across devices, with stakes ranging from €0.10 to €0.25 per spin. As the name suggests, it draws on the Wizard of Oz story and leans into a strong fantasy vibe. With a cartoon-like style set against an Emerald backdrop, Book of Oz is easily the best online slot Triple Edge has produced so far.

Book of Oz Symbols & Paytable

In true book-slot style, the lower-paying symbols are A, K, Q, J and 10 card icons, while the higher-value symbols—keys, hearts, books and wizards—feel a little different, giving the game a more distinctive edge. As expected, the book acts as both scatter and wild, meaning it substitutes for all symbols. While the biggest potential sits in the free spins, there’s still value in the base game too. Hit 5 wizards on a payline and you’ll collect 500 times your stake.

Underneath, it’s a simple old-school slot, but the Respin feature adds a nice layer of interest. After any spin, you can choose to re-spin individual reels as many times as you like to chase winning combinations. This is especially useful if you’re hunting for that third book or you’re a single symbol short of the 500x base-game win. Just keep in mind that respin costs are based on potential, so it’s best not to hammer the respins without thinking.

Book of Oz Free Spins

The free spins round is triggered, naturally, by landing 3, 4 or 5 books anywhere on the screen. That awards 10, 12 or 25 free spins respectively. And if you’ve played Book of Dead or Book or Ra (most players have), you’ll know the routine: one symbol is randomly selected as the special symbol, and it expands on the reels during free spins to create bigger wins.

We found it to be every bit as retrigger-happy as other book slots, so there’s plenty of suspense along the way. Land full-screen Wizard symbols during the feature and the 5000x jackpot is yours.

Book of Oz Conclusion

Book of Oz isn’t simply another book slot with a new coat of paint. The respin feature genuinely lets you make tactical choices, and it could easily become a trend in online gaming—especially as developers keep pushing new ideas like bonus buy options and MegaWays mechanics. This is the strongest release we’ve seen from any of Microgaming’s partner studios, and the team at Triple Edge definitely earned a well-deserved cold beer after work.

It’s already available, and the reactions we’ve heard from readers so far have been very positive. In fact, we’re heading off to play it ourselves. Remember to post your biggest wins in our forum. Cheers.
