Book of Oz Lock 'N Spin

Developed by Games Global, Book of Oz Lock 'N Spin is a 5 reel, 10 payline video slot. The title is designed by a collaborating independent company – Triple Edge Studios. The team worked together to create the sequel for the popular Book of Oz game, adding some new features and design tweaks while keeping the basics the same.

The rewards are pretty generous, reaching a maximum of 5000x your stake or £125,000. The bonus features include the newly added locked reels, along with Scatters, a Free Spins round and special expanding symbols. The RTP is set at 96.60% which is average for a slot of this sort.

Theme and Appearance

Design-wise, the slot is based loosely on the Wizard of Oz. The setting is supposed to represent the Emerald City and has a definite fantasy feel. The reels are filled with A, K, Q and J card suits, as well as 3 different potions and a character sporting a top hat. The latter is the most valuable, with 2, 3, 4 or 5 on a payline giving you 1, 10, 100 or 500x your stake respectively. The Wild symbol is represented by the Book of Oz and replaces all the symbols bar the Scatter. Graphics-wise, Book of Oz Lock 'N Spin is almost identical to the original game. There have been some slight design tweaks but nothing too noticeable. For the most part, the slot still looks pretty boring.

Betting and Prizes

When setting your wager in this slot, you choose the total amount instead of your bet per line. You can play from as little as 10p per spin if your budget is limited. Those with a bigger budget can increase their wager up to £25 per spin, or £2.50 per line.

Volatility wise, Book of Oz Lock 'N Spin is high. As you'd expect, this means that it delivers some pretty big wins. The top payout is 5000x your stake, which could be as much as £125,000 if you're playing with the maximum wager. To do this, you'll have to fill the entire grid with high-paying symbols. While the chances of doing this are fairly slim, the Free Spins and special symbols definitely help. However, remember that the game has high volatility, so don't expect too much from it. The RTP is set at 96.60%, which is a fair amount over the industry average. This may help the game to attract attention.

Slot Features

In terms of actual features, most are the same as the original Book of Oz. However, certain things have been added including the Hyperspin and the Second Chance feature. Below, we explore these in more detail.


Book of Oz Lock 'N Spin benefits from the Hyperspin feature. This will allow you to pay money to unlock certain reels and re-spin others. Also known as the Lock N Spin feature, this feature allows you to lock a maximum of four reels while the remaining reels re-spin. The price of this luxury varies, so we can't give a fixed amount. It depends on the potential rewards of the respin.

Free Spins

Like the original slot, the sequel boasts a Free Spins feature. This is where the magic happens. The feature is triggered by landing 3 Scatters anywhere on the grid. Depending on how many Scatters you land, you'll receive between 10 and 25 free spins. When this happens, a symbol is chosen at random and will expand on the reels whenever it appears. As you'd imagine, this is a great way to increase your payout!

Second Chance

Second Chance is the other new feature in the sequel. This allows you to pick another expanding symbol if the first one isn't high-paying. Obviously, this is a gamble and the results are random. Choosing again could result in a more valuable expanding symbol or a lower-paying one.


Book of Oz Lock 'N Spin is similar to the original version of the game. However, it benefits from the added Lock 'N Spin and Second Chance features to increase your winnings. Volatility-wise, the game is high. You can win a maximum of 5000x your stake per spin during the base game, and even more during the Free Spins round if you manage to fill the grid with the top-paying icon. Like all high-volatility slots, Book of Oz Lock 'N Spin utilises a high risk/high reward set up. With this, wins tend to come less often but boast higher value. If you're a high roller looking for a simple but rewarding slot game, Book of Oz Lock 'N Spin will not disappoint.
