Book of Oz Lock and Spin Introduction

There are lots of 'books' in the world of online slots and lots of them belong to Egyptian deities and rulers, but how many of these 'books' belong to the mysterious land of Oz? Here we have the second installment of the Book of Oz series, this time labeled Lock 'N Spin. 

Compared to its predecessor, Book of Oz Lock N Spin slot comes with a couple of new features and a revamped graphics design. This is an invitation to try and rediscover the same game all over again and see if the improvements can deliver some big winning outcomes. 

The 'Lock' part of the title refers to the reels which can be locked, as part of the new thing that Microgaming has introduced, called 'Hyperspins'. This allows the players to lock individual reels and make the subsequent spin for a chance of a winning outcome. 

The top winning outcome per single spin can reach up to 5000x multiplied by the winning bet and there is a free spins bonus. Otherwise, the 10 paylines are behind five reels and three rows and the wins are paid from left to right. 

Book of Oz Lock N Spin Design

Microgaming have managed to reate a world with this game, even though the graphics are not a huge improvement from the previous installment. The effect of mystery is created by the green element that flanks the reel-set and swooshes and flickers as the game unfolds. 

The reel give way to a set of vials that are capped by one of the cards suits. These represent the high-paying symbols, while the low-paying symbols are the high cards, which is so typical of Microgaming productions.

There is a musical score in the Book of Oz Lock N Spin slot, and it's a decent attempt by the developers to create a mood for the gameplay. It works and it can pull you towards this alternative world. So, we are left with the thrill of the game that concerns the potential for winning outcomes. 

How to Play Book of Oz Lock N Spin Slot

Start the game by select the bet amount from the window that is labeled BET. The smallest bet is £0.10 per spin, which comes by way one penny dedicated to each of the ten paylines. The maximum bet is still a modest £25.00 per spin, which translates to £2.50 per payline.

There are few other amounts between these two ends and the players can choose either of those available by selecting the minus and plus buttons. To send the reels turning press the round button that is underneath the middle reel and to go with the autoplay option select the one that is to the right of Spin.

This button opens up a small menu with options where you can choose the number of automatic spins and set the option single win limit and/or a total loss limit. Once ready, press play and enjoy the show. If you want to speed up the reel action then use the thunder button in the bottom right corner of the screen.

A novelty in the world of online slots, introduced by Microgaming, are the Hyperspins, which is found in the Book of Oz Lock N Spin slot. It allows hte players to lock up to four reels at a cost, and let the remaining ones spin.
