Book of Oz Lock ‘n Spin Game Background

Book of Oz Lock ‘n Spin is a 5-reel, 3-row slot game based on the popular story; it was created and designed by Triple Edge Studios, and released by the same on 24th September 2019, and since then, it has grown to become a mainstay of many players around the world. The casino game is packed with a wide assortment of features and bonuses - including the Lock ‘N Spin mechanic - that help transform the slot into one that’s packed full of excitement. The slot also features 10 paylines and a max payout of 5,000x the stake.

Book of Oz Lock ‘n Spin Game Design

Triple Edge Studios has created something truly special with this slot. Load up Book of Oz Lock n’ Spin and you’re immediately transported to the Wizard’s Chamber, where the action takes place! As you might imagine from a casino game called Book of Oz Lock ‘n Spin, the slot’s primary colour is green. Two large columns occupy the left and right sides of the reels. The game grid dominates the screen with its gilded frame, although the actual reels are separated by glowing green vertical bars. The symbols are encased in different coloured squares. The music, dominated by guitar strumming and punctuated by drum beats, has a mysterious quality about it, which adds to the wonderfully immersive experience. If you enjoy this genre of slot, then we have other on-site entries in the Book of Oz series, such as the original Book of Oz, as well as its sequel, Legacy of Oz.

Book of Oz Lock ‘n Spin Mobile

Of course, Book of Oz Lock ‘n Spin is available on all mobile devices, including Android and Apple. All that’s required is a stable internet connection!

Book of Oz Lock ‘n Spin Symbols

The symbols are colourful and elaborately detailed and of course, fit the fantasy theme to a tee.

First up are the low-paying A - 10 card suit symbols; these pay between 5x - 7.5x the stake for 5-of-a-kind on the reels.

Above these are the comparatively higher paying Heart, Key, Courage and Wizard symbols; these have a payout of between 37.5 - 250x the stake for 5-of-a-kind on the reels, with the Wizard paying out the most out of this particular batch.

The slot has a unique symbol that acts as both the game’s Wild and Scatter symbols, represented by a gilded book with the word Oz on it. In its function as a Scatter, the symbol triggers the Free Spins feature. In its function as a Wild, it substitutes for all other symbols in the game.

Book of Oz Lock ‘n Spin Bonus Features

The slot game includes several bonus features, all of which are discussed below.

Free Spins

Triggered by landing 3 or more Scatter symbols on the reels. Here’s a quick breakdown:

  • 3 Scatters = 10 Free Spins
  • 4 Scatters = 12 Free Spins
  • 5 Scatters = 25 Free Spins

An expanding symbol is randomly awarded at the start of the feature. Players are given a one-time choice: keep the original expanding symbol or discard it and have a different randomly selected symbol awarded. This is called the 2nd Chance Feature.

Whichever randomly awarded expanding symbol players end up choosing, said expanding symbol expands to cover the reel and pays out when matching symbols land anywhere on a line. It’s worth noting that expansion only happens when it contributes to new wins, while it also pays on top of ordinary Free Spin wins. Finally, speaking of Free Spins, these can be re-triggered.

2nd Chance Feature

Let’s look at this feature in a bit more detail. As noted above, once the initial expanding symbol has been awarded, the player is given 2 options, Keep or Try Again.

Keep selects the original randomly awarded expanded symbol and proceeds to the Free Spins bonus round.

Try Again awards another randomly awarded expanded symbol and proceeds to the Free Spins bonus round.

Lock ‘N Spin Feature

Reels can be locked in place by selecting either the reel or the little open lock symbol at the bottom of every reel. At that point, the little open lock symbol turns into a little locked symbol. Reels can then be unlocked by again either selecting the reel in question or the little lock symbol at the bottom. Do bear in mind, however, that locking the reels comes at a cost.


Book of Oz Lock ‘n Spin is a fantasy-based slot game based on the classic book!

Moving on from the Oz theme but still keeping with Triple Edge Studios, we have Ancient Fortunes: Zeus and Ancient Fortunes: Poseidon Megaways for those who prefer Ancient Greek mythology.
