This time around, Book of Oz Lock ‘N Spin offers a 5 x 3 reel set which comes with ten fixed bet ways, and an incredibly tempting RTP of 96.6%. Even though you’ll see plenty of your stake in return, you’ll need to be mindful of the high volatility of this online slot – but that does mean when you create a winning combination, the award will be significant. The max jackpot up for grabs in Book of Oz Lock ‘N Spin is £125,000 which you’ll have a chance of winning if you’re spinning with the max stake amount of £100. More casual online slots players can spin from as little as 10p on all devices. The main attraction in Book of Oz Lock ‘N Spin is the brand-new trademarked Hyperspins bonus feature which is completely optional and allows you to lock anywhere up to four reels in place for your next spin – the cost of the re-spin will be dependent of the symbols on the reels at the time. It’s an incredible feature for any players who are looking to experience a more tactical online slots experience.

In Book of Oz Lock ‘N Spin, you’ll see a mix of traditional playing card symbols as the low-value symbols, and specially-themed symbols inspired by the wizard of Oz. The most you’ll be able to cash out on with symbols A, K, Q, J and 10 is 0.75x your stake. But the cash prizes take a drastic rise with the high paying symbols – especially with the top paying symbol which is the male character in the flashy green top hat, he’ll pay out 500x your stake every time you find five of him in a winning combination.

Book of Oz Lock 'N Spin Bonus Feature

There may not be all too many bonus features in Book of Oz Lock ‘N Spin, but the ones which the online slot does offer takes the gameplay to the next levels. Even though there is plenty to be won by putting together winning combinations of the standard symbols, the bonus perks will give those prizes a nice little boost!

Hyperspins Bonus Feature

Microgaming has recently introduced their trademarked Hyperspins bonus feature which is a hit with plenty of our players on Rose Slots. The bonus feature allows you to lock four reels of your choosing in place, the cost of locking each individual reel will be shown at the bottom of each reel, it is recommended to use this feature if you spot two of the scatter symbols on the reels, as it will give you a great chance to get the third scatter symbol to unlock the free spins – and once you learn what is offered in the free spins, you’ll definitely be excited to trigger it.

Free Spins Bonus Feature

You’ll be able to trigger the free spins bonus feature by finding three of the book of oz scatter bonus symbols on the same spin. Three, four, or five scatters will award you 10, 12, or 25 free spins, and you’ll have the chance to top up your free spins count by finding three or more scatter symbols while you’re spinning for free. Before you start the free spins round, one of the standard playing symbols will be chosen at random which can become an expanding symbol every time it drops in the free spins bonus round. You may have seen this feature before, but what you definitely won’t have seen before is the chance to swap your symbol with the ‘Second Chance’ feature. While you can end up with a higher paying expanding special symbol, there’s also the chance that you will end up with a lower-paying symbol – but still, it’s nice to have the option!


The most you’ll be able to win in Book of Oz Lock ‘N Spin is 5000x your stake when you’re spinning with the max stake amount. This can be won with every single spin in Book of Oz Lock ‘N Spin. Some of our players may find it slightly disappointing that there is no special jackpot prize to trigger, but plenty of reel spinners will be more than happy that the solid win potential comes with every single spin.

Book of Oz Lock n Spin 2021 

Book of Oz Lock n Spin is still the latest title to be released in Microgaming’s and Triple Edge Studios’ ‘Book of Oz’ series of slot games which puts an alchemic spin on the ‘book of’ format. So, if you’re a ‘book of’ slots fan, there’s still no better set of reels to spin than those contained in Book of Oz Lock n Spin which boast the innovative hyperspins feature which allows you to get technical with your gameplay and lock up to 4 reels on each spin. We’d highly recommend using this feature when there is a chance to trigger the all-important free spins bonus feature where the action gets even more intense. 

There’s also the nice added perk of being able to choose which symbol expands in the free spins feature. While it may seem like an obvious choice to choose the top-paying symbol, that isn’t necessarily the case as if you choose a lower-paying symbol, it has a greater chance of expanding when it hits the reel set. Even though the title was released in 2019, there is still plenty of talk of the title, here’s what had to report “Book of Oz: Lock N Spin has some interesting additions to its list of features…It’s a decent choice, for those that loved the original as well.” And had nothing but positive things to say about the clever bonus features on offer in the title which doesn’t deviate from the original but packs in plenty of additional excitement through the optional features.
