Book of Oz Lock N’ Spin - Slot Review

The Book of Oz: Lock N Spin is a high variance 5-reel, 10-payline title playable across desktop and mobile devices and accepting bets in the range 0.10 – £25 per spin. Design-wise, it is not a big departure from the original, but feature-wise, it comes with some improvements you may find fascinating.

Hyperspins Feature

During the base game you have the chance to lock some reels and re-spin others in an attempt to score a win. You will be able to do that at a calculated fixed price that is determined by the probability of landing a win.

Free Spins

Land 3, 4 or 5 scatters to get 10, 12 or 25 free spins, respectively. The book scatters appear during the free spins round, so a retrigger is also possible.

Second Chance Feature

The Second Chance feature enables you to reshuffle the symbols and form a winning combination. This is a two-bladed knife, though. On one hand, you don’t have to pay to use the Second Chance feature. On the other hand, you may land worse symbols that those you previously landed.

Bottom Line

The Book of Oz: Lock N Spin is a demonstration that Microgaming can do better than releasing run-of-the-mill slots with a sole free spins bonus round that is impossible to trigger. Well, we would not have turned down some expanding wilds or multipliers, but overall, we are pleased with the job Microgaming has done here.
