Book of Oz slot game review

Book of Oz is a Triple Edge Studios “book slot” published on Microgaming's collaboration platform. The game was launched 12 December 2018, and it comes with 5 reels, 3 rows and 10 paylines, like so many Book-copycats. What truly makes this game unique is the Re-spins feature. Here you get to spin single reels as many times as you like (for a cost) to create winning combos, and hopefully trigger the all-important free spins feature.

Book of Oz RTP, variance & technical data

The RTP on Book of Oz is 96.31% in the base game, and on regular spins. However, on Re-spins the RTP increases to 96.5%. Either way, the RTP does not stick all that much out from the industry average of 96%. Please also note that his is a highly volatile game, and you’d be wise to adjust your bets to a level your bankroll can handle.

Book of Oz Review

While Book of Oz is released on the Microgaming platform, it’s Triple Edge Studios that deserve the credit for this game. It’s based on the classic and timeless Book of Ra (like so many similar slots), and it comes with more or less the same game mechanics. However, as usual there is a twist, and on Book of Oz this twist is more interesting than what we’ve seen on many similar “copycats”.

The Re-spin feature that allows you to spin single reels as much as you want is something rarely seen before (if ever). Sure, you’ll have to pay a little bit for each re-spin, but this is almost like having a nudge that never stops (until you want it to). It certainly makes the base game more fun, and it also helps you trigger the all-important free spins feature where the big wins up to 5,000x are hiding.

Book of Oz symbols

Book of Oz comes with symbols inspired from the famous story, and you need 2 to 5 high value symbols on a payline to win (or 3 to 5 low value symbols):

  • Green Hat Wizard - is the highest value symbol and pays 250x
  • Lion Head - pays up to 100x with 5 on a payline
  • Book - is the scatter symbol and pays anywhere it lands up to 100x for 5
  • Key - is the lowest value premium symbol and pays 37.5x
  • Heart - same as Key and also pays 37.5
  • Card suit (A, J, K, Q and 10) - low value symbols that pay either 7.5x or 5x

Book of Oz bonus features

Book of Oz does not come with that many bonus features, which makes what little you get even more important. The most unusual feature is the Reel Re-spin feature you can benefit from in the base game, as we have not really seen this on any other game before. Simply put, you can pay to re-spin any reel as many times as you like in order to complete a winning combo, or to activate the all-important free spins feature which we will discuss below.

Book of Oz free spins

The free spins feature on Book of Oz slot is triggered when you land 3, 4 or 5 Book scatters on the reels at the same time. This will give you 10, 12 or 25 free spins respectively, and you can also re-trigger the feature by landing at least 3 scatters on a single free spin.

There is no limit to how many free spins you can get this way, so you never know how long this feature will last. Just like you know from other “book slots”, 1 symbol will be chosen randomly to function as the expanding symbol in the free spins feature. It will then cover one or more reels, and boost your winning chances for sure.

Book of Oz jackpot (max win)

There is no progressive or local jackpot to be found on Book of Oz, but that’s not gonna stop you from taking home some serious payouts form this game. The max win is 5,000 times your stake, and this amounts to £125,000 as long as you play with the highest bet level. This is a pretty good potential, even for a high volatility game, but it’s somewhat limited by a low max bet level.

Book of Oz mobile & tablet

Sure, you can play Book of Oz on both mobile and tablet if you so desire. This game is optimized for all platforms and handheld devices. Play anywhere you want using your Android devices or your iPhone and iPad.

SlotCatalog verdict

Book of Oz brings something new and fresh to the “book slot” genre, and the innovative single reels re-spin feature might just catch on and become the “new thing” in the industry. A lot of obscure games have spun out of the Microgaming partnering machine for many years, but Book of Oz is certainly one of the better releases on this platform. The volatility and potential is high, and any fan of the “book” genre should definitely check this one out.


  • Unlimited single reels re-spins (for a cost)
  • Free spins with expanding symbols
  • High variance and potential up to 5,000x


  • Not for those you don’t like “book” slots
  • Max bet level is a bit low
