Book of Oz Lock N Spin Online Slot Machine – Free Play & Review

The same Oz inspired graphics are present on the reels of this game, and the focus is still on the Book style mechanics as before.

They didn’t change much here, and in fact you will find the exact same design as in the past. You will have Book symbols, along with Royals and several potion bottles holding liquids colored in blue, pink or red.


Book of Oz Lock N Spin is coming via Triple Edge Studios, as an exclusive release that’s ordered by Microgaming, to be available on their platform alone.

The developer has done this a lot lately, and the quality of the slot machines hasn’t been that different from what the company offered on its own in recent years. Triple Edge Studios has a bit of experience already, as they launched several other slots for Microgaming.

How To Play It

It’s not the biggest betting range around, as it starts from a minimum of $0.10, and it can end up at a high level of $25 per spin. In exchange, the slot offers you 10 active lines, which takes the line bet from $0.01 to $2.50.

Expect to find a slot machine with 5×3 reels, 10 active lines, and a feature system that is typical for the Book-style slots. If you’ve played the popular Book of Ra from Novomatic, you know what this game has to offer. It also has a couple of extra options, for players that might be interested in them.

Special Features

It’s not a very different release, compared with the first Book of Oz slot, and you play it about the same way as before. They’ve just added a couple of extra options, called Hyperspins and Lock N Spin, but those are optional.

First of all, the game will use its Book of Oz symbol as both the wild and scatter, which is typical for these slots. You can get these Book symbols to participate in various winning combinations, just by having them land on the right lines and acting as substitutes.

Should these wilds appear 3 to 5 times, they give you access to 10 to 25 free spins. In this mode, the Book chooses one of the regular symbols, and turns it into something special. The special symbol has the ability to expand and take over its reels, and it makes it more likely that you can end up with a screen filled with matching symbols.

Before the free spins begin, you can use the Second Chance option, to try and get a better special symbol. Use it, if you’re not satisfied with the first symbol that the game gave you.

Hyperspins is an option that lets you re-spin certain reels, while locking up to four others. This is the improvement added to this game, the option to lock multiple reels and re-spin the others. In the previous game, you could just respin one reel at a time.

Maximum Payouts

You will get a chance at some serious top payouts with Book of Oz Lock N Spin. The slot’s maximum reward will reach 5,000x total stake, so up to $125,000 could be paid here.

Book of Oz Lock N Spin is considered a slot with High volatility, which at the same time has an RTP of up to 96.60%, excellent for a modern game.


Book of Oz Lock N Spin is a very similar game to the original, but if you are interested in using Hyperspins, you can safely make the switch from the older version to this one. They’re not very different otherwise.
