The main theme utilized by the Book of Oz slot game is one of magic and wonder, with a sea of green light shining at the back of the reels and leeching into the symbols themselves. But this aesthetic is overshadowed by the game’s main feature, which is active during the base game.

Known as a “lock ‘n spin”, it lets you lock reels in place at the end of each spin. Just select the “lock” option below your chosen reel, pay the extra stake amount, and then spin. Your chosen reel will remain in place while all of the others spin.


If you’re a little confused by how the “lock ‘n spin” feature works, you can experiment with it in demo mode. Available to online Canadian casino members, this mode allows you to trial the game before taking a real money spin.

Pay no attention to the man behind the curtain and focus on the golden book instead. The titular Book of Oz is a gilded tome that sits enticingly on the reels and promises a feature that offers as many as 25 free spins. You need to reveal all 5 of the Book Scatter symbols to unlock this many spins, but 3 will also give you 10 spins while 4 awards 12.

It’s a traditional slot game feature and while it doesn’t offer anything as unique as the “lock ‘n spin” mechanic outlined above; it serves as the perfect accompaniment. It’s not just about the spins, either, as the scatter also awards an instant win of either 1x, 10x, or 100x, depending on whether you reveal 3, 4, or 5.


The Lock ‘N Spin feature comes alive on mobile and it’s the best way to experience it. In a way, it’s similar to the old-school “nudge” feature found on classic mechanical slots, only you have to pay a little extra to hold the reels in place. Being able to use this feature on a mobile device feels great, especially for players who are used to using similar features on clunky slot machines.

Book of Oz Lock ‘N Spin is definitely not the exception, so if you’re looking for a unique gaming experience, be sure to sign up at a legal online gambling site in Canada that supports the gametoday.
