This fantasy-inspired slot is based on a truly classic theme, with the ‘Wizard of Oz’ one of the most iconic tales ever told.
So, we’d definitely recommend that you check out the demo reels above, simply by clicking through the ‘Play Now’ icon in the bottom right-hand corner of the display. Then, you can spin the reels for free and see exactly what the slot has to offer!
What Are the Characteristics of Book of Oz Lock n Spin?
Available through Microgaming’s collaborative platform, Book of Oz Lock n Spin borrows heavily from the excellent Book of Dead and builds on this with its innovative ‘lock and spin’ feature (we’ll explore this in more detail below).
At the heart of the game is a dark and mysterious 5x3 reel grid, which features a total of 10 paylines and traditional winning combinations that are forged from right to left.
The slot also provides a relatively broad betting range, with casual players or those with smaller bankrolls able to wager as little as €0.10 per spin.
At the other end of the spectrum, higher rollers can stake as much as €25.00 per spin, which is fairly typical for a high variance slot that delivers relatively infrequent (but often sizable) payouts.
Unsurprisingly, it’s during the slot’s main bonus round that you’re able to land the top prize, which is fixed at 5,000x your initial stake. However, it’s incredibly hard to trigger such a payout, as much will depend on the special ‘expanding’ symbol that’s selected at the beginning of the free spins round.
Due to its high variance and the aforementioned lock and spin feature, Book of Oz Lock n Spin offers a variable return to player (RTP) rate of anywhere between 96.35% and 96.60%.
Either way, you can expect to recoup between €96 and €97 for every €100 wagered through the slot on average, which is a competitive rate of return by anyone’s standards!

What Are the Bonus Rounds Like on Book of Oz Lock n Spin?
We’ve already touched on the slot’s two main bonus features, which can combine to help you win more often and simultaneously boost the value of your returns.
So, here’s a more detailed breakdown of these features, including how they’re triggered and what they add to the overall gameplay experience?
The Lock n Spin Feature
This feature really sets the slot apart, primarily because it provides an effective way of optimising your access to the lucrative free spins round on Book of Oz Lock n Spin.
With the innovative ‘lock n spin’ feature, you can lock up to four reels of your choice after every single spin. This can be done simply by clicking through the padlock icon beneath the relevant reel, while it will cost a variable amount of money to lock each reel depending on the value of symbols in play.
For example, if you lock one or two reels that feature the coveted Book of Oz wild or scatters (you’ll need three to trigger the free spins round), you’ll have to pay a premium and commit more of your bankroll.
The total amount will display towards the bottom left-hand corner of the reels, and you should always measure this against the potential payouts that you’re pursuing.
Certainly, this is an excellent way of triggering the free spins round more frequently during the base game, and it’s this feature that ultimately unlocks the slot’s biggest prizes.
The Free Spins Feature
When you land three, four or five of the Book of Oz scatters, you’ll earn 10, 12 or 25 free spins respectively. You’ll also earn a cash prize of two, 20 or 200x your stake, which ensures a neat payout as you head into the bonus round.
Before you access your free spins, a specific symbol will be chosen at random. When you land this ‘special’ symbol during the free spins, it will expand to cover the entire reel and can boost the value of your payouts significantly.
Book of Oz Lock n Spin has also introduced the second chance feature, which affords you a single opportunity to improve the expanding symbol initially selected. This way, you can take another shot at landing the game’s highest paying icon, increasing your chances of filling all five reels with ‘The Wizard’ and landing the top prize of 5,000x your stake.
As if this wasn’t enough, you can even retrigger the feature during this period of gameplay and earn up to 50 free spins in total.
What if I Want to Play Book of Oz Lock n Spin from My Mobile?
Launched in 2019, Book of Oz Lock n Spin is a slot that’s powered by HTML5 technology. As a result, you can access it seamlessly through your desktop, smartphone or tablet device, with the game’s interface adapting intuitively to suit the dimensions of your display.
Most of our recommended casinos enable you to play the game on a responsive mobile site or native casino app when on the move too, making Book of Oz Lock n Spin the ideal slot during the daily commute to and from work!
What Other Games Are in the Book of Oz Lock n Spin Series?
The Book of Oz Lock n Spin boasts huge similarities to Book of Dead and Book of Ra Deluxe, but if you’re a fan of the slot, there’s a much wider range of games that you may also like.
We’ve selected three of the most popular such titles below, based primarily on the quality of their gameplay and the potential payouts on offer.
- The Marvellous Mr. Green: This NetEnt slot is deceptively similar to the Book of Oz and Book of Oz Lock n Spin, although it features a higher number of paylines (20) and a slightly larger base game prize. The free spins round is also generous and includes multipliers of up to 5x your stake.
- The Wizard of Oz: This is where the origins of Book of Oz Lock n Spin can be traced back to, with the first ever Wizard of Oz inspired slot having been launched by WMS more than 10 years ago. We love this slot’s range of bonus features, while a top prize of €50,000 is likely to appeal to every single slot player!
- Berry Burst: Another incredibly popular online slot, Berry Burst is a NetEnt favourite and one that focuses heavily on lucrative respins as a core feature of its offering. A relatively new addition to the market, Berry Burst is also popular around the world and brings a dash of colour to a crowded marketplace.
A Word on Responsible Gambling
Despite its relatively modest betting range, it’s still possible to wager up to €25 per spin through Book of Oz Lock n Spin. Such stakes can quickly accumulate over time, so it’s important to wager responsibly and ensure that your total bankroll never exceeds an amount that you can afford to lose.
You can also manage your bankroll by setting daily, weekly or monthly deposit limits through your chosen casino platform, depending on how often you wager and your precise betting habits when gambling online.
Final Words on Book of Oz Lock n Spin
Whether the Wizard of Oz brings back fond memories from your childhood or you simply want to play a high variance slot that boasts a competitive RTP rate, Book of Oz Lock n Spin is a game that we can highly recommend.
The slot is also set apart by its creative ‘lock and spin’ feature, which allows you to lock specific reels for a specific cost and increase your chances of landing lucrative winning combinations or triggering the generous free spins round.
This feature is also highly important from a strategic perspective, especially if you want to optimise the slot’s variable RTP rate and boost your bankroll over time.
