BOOK OF OZ LOCK 'N SPIN SLOT REVIEW

Book Of Oz Lock 'n Spin is an online slot developed by Triple Edge Studios for Games Global (Microgaming). The slot explores the famous Wizard of Oz story and is a sequel to the Book of Oz game by the same software provider. Both slots share the same design, gameplay mechanics, and features, with the only exception being the addition of the lock and respin feature in this version of the popular slot. Book Of Oz Lock 'n Spin slot has five reels, three rows, and 10 paylines. This is a high-volatility book slot with an RTP of 96.35%. 

ABOUT THE BOOK OF OZ LOCK 'N SPIN SLOT 

Book Of Oz Lock 'n Spin is Games Global’s follow-up to its highly successful Book of Oz online slot game. In fact, a side-by-side comparison shows that both games are almost identical. The reel setup is the same and even the backdrop of the game and the soft enchanting music playing in the backgrounds are the same as the original. 

Like its predecessor, the new slot invites you to step into the emerald city where the powerful Wizard of Oz himself awaits with various potions. The slot’s background is a large ballroom with a glass window and massive emerald pillars. Overall, the design of the game is simple and enchanting, but the absence of familiar Wizard of Oz characters is still a notable flaw of this game. 

GAMEPLAY 

WAGER

Book Of Oz Lock 'n Spin is a simple slot game with straightforward gameplay. The game has five reels, three rows, and 10 fixed paylines. To start each round, you need to set your preferred stake, which is a minimum of $0.10 per spin. A winning combination is formed in this slot by matching identical symbols on adjacent reels of a payline from left to right. At least three low-paying symbols or three high-paying symbols are needed to form a winning combination in this game. 

SYMBOLS

As mentioned above, the symbols in Book Of Oz Lock 'n Spin are the same as that of the original Book Of Oz slot. They’re centered on the Wizard of Oz himself and his magical potions of courage, love and intelligence. 

The Wizard in the top hat is the most valuable symbol in this game. This symbol offers a payout of 500x the total bet amount when five matching symbols land on a pay line. The blue potion with the lion statue represents courage and pays 200x for five symbols on a pay line.

The purple potion with a Key represents intelligence while the pyramid glass with a heart symbol is the love potion. These two symbols pay 75x for a five-of-a-kind combination. 

The slot also has card symbols as the low-paying symbols. The A and K cards pay a maximum of 15x for five symbols on a payline. Similarly, the Q, J and 10 cards pay 10x for a five-symbol combination. 

The main bonus symbol in this game is the book symbol. This symbol is both the Wild and the Scatter symbol. It is a paying symbol as well, offering a payout of 2x, 20x and 200x for three, four and five symbols on a payline. 

SPECIAL FEATURES 

Book Of Oz Lock 'n Spin has the classic “book of…” slot mechanics. Like similar games with this feature, the book symbol acts as the Wild symbol, meaning it can substitute for any of the other standard symbols in the base game to form a winning pattern. 

This slot also has an expanding symbol bonus, which is only active during the free spins bonus round. Before the bonus games begin, one of the standard symbols is selected as a special symbol. If this symbol forms a winning combination in the bonus round, it becomes and expanding symbol, filling up any reel it lands on, triggering bigger payouts. 

Of course, the highlight of this game is the Lock’n Spin feature. In the original game, you have the option of spinning individual reels to change the outcome of a spin for a calculated cost. This gives you another shot at landing a winning combination after a base spin has been completed. 

In Book of Oz Lock 'N Spin, the software provider introduced a twist to this second chance feature. Instead of spinning just one reel while the others stay in place, you can lock specific reels with the desired results and spin the other reels. You have the option of locking up to four full reels this way. The locked reel feature gives you a chance to complete winning combinations or trigger a bonus feature.  The cost of locking the reels depends on your probability of ending up with a win at the end of the respin. 

BOOK OF OZ LOCK 'N SPIN FREE SPINS FEATURES

The book symbol is the key to unlocking the free spins feature in the Book of Oz Lock 'N Spin slot. Landing three, four, or five of this symbol on the reels will trigger the free spins bonus round with 10 free spins to start. This bonus can be retriggered if more Scatters appear on the reels during an ongoing free spins bonus round.

Another way to get free spins is through casino bonuses. Online casinos typically give players free spins as part of various bonuses and promotions. For instance, new players on EnergyCasino can get no-deposit free spins as a welcome bonus on the casino. Older players can also get free spins through ongoing promotions like loyalty rewards, deposit bonuses, and tournament prizes. 

BOOK OF OZ LOCK 'N SPIN FREE PLAY (DEMO)

Before diving straight into playing Book of Oz Lock 'N Spin for real money, it makes sense to try it out first in demo mode. Playing in demo mode allows you to figure out how the slot works, and decide if it is enjoyable for you before you start playing with real cash. 

In the Book of Oz Lock 'N Spin demo version, the casino gives you virtual funds which you can use to bet on reel spins instead of real cash. The demo version of this game is just like the actual game. The only difference is that you cannot withdraw your winnings as real cash when you play in demo mode.  

Depending on your jurisdiction, you may be asked to register and complete the verification process to access the demos. However, if you live in a location where verification is not necessary, you will be able to play as a visitor.
