Book of Oz Lock’N Spin

The developer of Triple Edge Studios upgraded a bit Book of Oz slot at the request of Microgaming, and as a result, the twin Book of Oz Lock'n Spin appeared with some differences.

Visually, the novelty does not differ from the predecessor that gained popularity. All of the symbols, design, sounds remain the same.

Slot system, symbols

It makes sense to recall that Book of Oz Lock'n Spin has the same field format of 5x3 with 10 paylines and the minimum stake of 10 cents.

The best payout in regular rounds is x500 for a full line of wizards. And books are both wilds and scatters.

The rest is usual and traditional for slots of this type, where the main event is a bonus round with prize spins.

Bonus features

The creators of Book of Oz Lock'n Spin game added Hyperspins option. In Book of Oz slot you could fix any of the reels and spin the rest for extra money. Again, the creators went even further, offering a player to lock up to 4 reels at the same time and continue to catch a desired combination on the remaining one.

Obviously, the cost of a spin will depend on combination potential and locked reels.

The described feature is the only difference in the new Book of Oz Lock'n Spin game. Specially for it, payout mathematics was recalculated.

Free spins round

A free spins bonus round remains unchanged. 3-5 scatter symbols will give you from 10 to 25 free spins. Before starting the bonus, the main symbol will be randomly determined. It will be expanded to the entire reel when appeared in sufficient amount.

By the way, you can re-select the main symbol if you don't like it for any reason. You will be given only 1 chance to update it, and it's not a fact that a replaced symbol will be better than the first.

3+ scatters will bring a retrigger with a choice of one more main symbol.

Provider's fee

Microgaming did not invent a new thing and kept the same fee as for Book of Oz. It is 3.40% of a stake from each spin.
