Book Of Oz Slot

Historically, Microgaming has been one of the most successful online slot developers that the industry has ever seen, with the Malta-based company churning out several classics such as Mega Moolah. In recent years, the company has extended a helping hand to some brand-new developer studios, with Triple Edge Studios being one of the most successful.

The great thing about this dynamic is that providers such as Triple Edge Studios get to put a huge amount of zeal to creating the first slots in their catalogue, and Microgaming gets to distribute these games across their vast network. Book Of Oz is one of the first collaborations between Microgaming and Triple Edge Studios, and if this game is anything to go by, this is a link-up we are going to see again and again. Read on for a Book Of Oz slot review. The slot was launched in December 2018 and has quickly became a favourite of many gamers.

A general overview

As you might have guessed from the title, Book Of Oz takes the wonderful world of The Wizard Of Oz as a major theme, however, the action is more preoccupied with the mythical wizard, rather than Dorothy and co. As such, this slot’s aesthetic is steeped in deep emerald greens, with Triple Edge Studios and Microgaming showing their prowess with some seriously impressive HD graphics.

The slot utilises the classic 5-reel grid configuration and also has 10 pay lines, something that might disappoint some slot gamblers used to more pay lines, however, it proves to be more than enough to make some big wins on. Line bets start at just 0.01 and go all the way up to 2.00, which means that the maximum bet that gamblers can place on one spin is 100.00. One thing is certain, high rollers are going to love Book Of Oz…

Book of Oz Symbols

Book of Oz has a great range of symbols which are inline with the famous story, players need to combine 2 to 5 high value symbols on a payline or 3 to 5 low value symbols to form a winning combination. Here is a breakdown of the symbols (there is also a full paytable available in the menu):

  1. Green Hat Wizard – Most valuable symbol which pays 250x
  2. Lion Head – 5 on a payline pays up to 100x
  3. Book – This is the scatter symbol and pays anywhere it lands up to 100x for 5
  4. Key – Least valuable premium symbol and pays 37.5x
  5. Heart – This is the same as the Key symbol and pays 37.5x
  6. Card symbols (A, K, Q, J and 10) – pay between 5x and 7.5x

Book Of Oz Bonus Features

It makes perfect sense to expect some pretty lucrative bonus features from Book Of Oz, and the good news is that Triple Edge Studios and Microgaming have offered exactly that. Book of Oz does not have that many bonus features however the bonus features on offer are of the highest quality.

The Reel Re-spin feature is very unique and adds a completely new dynamic to the slot. We have not seen this feature on many other games, you can choose to pay to re-spin any single reel as many times as you would like in order to form a winning combination. The Re-Spin feature can even be taken advantage of in order to activate the free spins feature. Each reel has a different price to re-spin depending on how close to a win you may be, the higher the price of the reel then that could imply that a lucky spin could land you a win.

The free spins feature is launched when a player lands 3, 4, or 5 Book scatter symbols on the reels at the same time. Players will receive either 10, 12 or 25 free spins, you can also land more free spins if you land more than 3 Books in any of your free spin rounds. This is a great chance to boost your pot if the free spins are favourable. Book of Oz does not limit players on how many free spins you can win through this way, so in theory players could grab infinite free spins.

Just like with other book slots, one symbol is chosen randomly which will expand across one or more reels during the free spins feature. This will give players a lot of opportunity to make a lot of winning combinations which could be profitable.

Book of Oz does not have a progressive or local jackpot, however there is still some very big wins up for grabs still. The biggest win that can be accumulated is a 5000x your stake, this means the jackpot stands at a huge $/€/£125,000 if you play with the highest level of bet.


Book of Oz has a very good RTP of 96.5%, this is above the industry standard. The return to player means that on average if a player stakes $/€/£100 then they should return $/€/£96.50. The game is a high volatility so has great potential for players to land some big wins.

Microgaming is responsible for some fantastic things such as their Progressive Jackpot Network, and the titans of the slot industry have chosen to work with smaller companies such as Triple Edge Studios in order to help them reach their maximum potential.
