The design in Book of Oz Lock ‘N Spin is impressively done, giving just a slight nod to the Wizard of Oz story. Emerald (as in Emerald City) dominates the screen and the position symbols are embellished with hearts and lions. It all looks rather good. The best standard symbol is the wizard (who looks nothing like a wizard). The book is both the wild and the scatter.
Lock ’N Spin feature
Once a spin is complete and you’ve surveyed the reels, you’ll be offered the chance to buy a respin with the Lock ‘N Spin feature. This allows you to lock between 1 and 4 reels and spin the rest again. The price for each respin varies. It does offer you the chance to land a bonus trigger or improve an already potentially decent combination.
Free spins with expanding symbols
The other feature is the Free Spins feature which is activated by landing 3, 4 or 5 of the book wild/scatter on the same spin. Your reward is 10, 12 or 25 free spins. Before they start, 1 symbol is randomly picked to be the special expanding symbol. This fills the reel whenever it hits. If you don’t fancy the special symbol you’ve been awarded, you’ll have the chance to exchange it for something else. Retriggers are possible here too meaning up to 50 free spins in total.
Payouts of up to 5,000 x stake
Book of Oz Lock’ N Spin might have a fantastical look but it can deliver some pretty serious action. Potential payouts can reach up to 5,000 times your stake per spin or free spin. Be warned though, this is an extremely volatile slot game. If you like the magical theme and high variance play, then you’ll find both in this innovative new arrival to the Oz collection.
