Book of Oz: Lock ‘N Spin Slot Review

Book of Oz: Lock ‘N Spin Slot Big Image

Book of Oz: Lock ‘N Spin is the newest collaboration between Microgaming and Triple Edge Studios, the latter being the developer for this sequel that’s heavily based on the original Book of Oz slot. Mostly, we’re seeing the same slot machine, with a couple of additions to the way it can be played.

This game’s setup works on 5 reels with 10 active paylines. The slot will pay fairly well, with a 5,000x maximum payout, which could be turned into a reward of $125,000, given the right wager. The game does well in a couple of other areas, with the RTP being set to 96.60%. I’m good with its features as well, and even though it’s a typical Book-style slot, with free spins and special expanding symbols, this version also adds the Second Chance and the Lock N Spin paid option.

Betting and Prizes

The lowest wager per line is $0.01 here, so the minimum total bet is $0.10. At the other end, we get a line bet of $2.50 and a total bet of $25 per spin.

You are looking at a game with some major potential, with its expanding symbols making it a little bit easier for entire screens filled with matching symbols to exist. The 5,000x jackpot which the game promises, can turn into $125,000 cash, and that’s not a bad payday. Even the game’s RTP, which is set to 96.60%, tells us that it does a little bit better than a lot of its competitors. Do expect the game’s volatility to be High, it can’t be avoided when you’re talking about big rewards.

Book of Oz Lock ‘N Spin Slot Features

Now, you’re going to find that the game didn’t change that much, compared with the original Book of Oz, but it did add a couple of extras, which make it more interesting.

The regular side of the feature section, consists of the scatters which will trigger the free spins for you. The symbol doing this has the image of the Book of Oz, and you’re going to need it appearing scattered, a minimum of three times in random positions. 10 to 25 free spins trigger next, depending on the number of symbols contributing.

Before the feature starts, a random symbol is chosen, to gain the ability to expand whenever it appears, covering its reel. What this game adds extra, is the Second Chance option, which allows the player to ask for another random symbol, if he isn’t satisfied with the first one he got. It’s just as random the second time, so you can do better or worse.

Hyperspins is the other major feature, introduced with this version of Book of Oz. It adds the option to lock reels, up to four of them, re-spinning the ones that you don’t keep. You have to pay though, an amount which changes depending on the potential outcome.

Theme & Design

Inspired by the Wizard of Oz, the slot machine is not going to change much design wise. They focused mostly on features, when designing this sequel, so we get the same mostly dated graphics as in the original. The design is not one of the game’s strong points. We see images of Royals and potion bottles, along with the Book symbol, but I’m not impressed with any of it. This is definitely one area where they could’ve spent a bit more time, especially since a sequel is supposed to be an improvement over the original, not just a clone.


In Book of Oz: Lock ‘N Spin, we find a couple of extra features, but you either pay extra to use them or they have little consequence over the slot’s action. All in all, it’s a slot for the fans of the first Book of Oz, and an OK choice overall, just not a great one.
