Book of Oz Lock ‘N Spin Slot Features

In a complete reversal from the original Book of Oz slot, you can now lock any reel instead of respinning it on any spin in the base game. Using the Lock ‘N Spin feature, you can lock up to four reels on each occasion. The five displays at the bottom of the game window will light up after the reels have stopped to show an extra bet amount for each reel. The amount is based on which symbol is missing and what kind of win could happen should the missing symbol appear on the respins. The higher the win potential when the symbol lands, the higher the bet amount for locking the respective reels. The mechanic also works for scatters when only two appear on a spin.

Hit minimum three, four or five scatters anywhere on the reels in one spin to trigger 10, 12 or 25 free spins respectively, which can be re-triggered indefinitely. Additionally, a coin win of 2x, 20, and 200x is awarded for three, four and five scatters. Before the bonus round starts, one of the nine regular pay symbols is randomly selected as the special symbol. When sufficient land on a free spin, they will expand vertically to cover the entire reel and award wins for all pay lines, which are paid on top of any potential organic wins from the spin. It will need minimum three low-paying symbols or minimum two premium symbols anywhere on the screen to see them expand and award a win.

However, there is one twist which comes into after the first random special symbol selection. If you are not happy or do not like the selected symbol, you can use the 2nd Chance to have a different symbol chosen. Worth noting is that you can equally end up with a higher or lower value symbol.

Final Verdict

The original Book of Oz game offered already solid “Book” slot action with high volatility and equally high win potential of up to 5,000 times bet. Turning the Respin feature on its head with the Lock ‘N Spin is an interesting twist while the 2nd Chance offers more variety for the expanding symbol. Overall, an improvement over the original and a decent game from Microgaming that deserves a few spins in any slotting session.
