Book Of Unseen Slot Review

Whether you’re looking to expand your repertoire of slots that are perfect for spooky season or you’re just interested in seeing what Ruby Play has to offer, Book Of Unseen is a medium- to high-volatility game that is likely to capture the attention of many players. There are some solid features here, including free spins and expanding wilds, so let’s see if we can get to the bottom of the mystery that lies within…

Mystery and Intrigue Await!

Featuring plenty of mysterious imagery, including women hiding behind gold masks, curious keys, and grand pillars framing the reels, the intrigue that washes over you as the game loads is enough to set it apart from many other slots that might otherwise capture your attention during the autumn months.

There are plenty of excellent touches throughout, including the flickering candles and the orbs floating around while being illuminated by beams of light emanating from behind the reels.

The soundtrack also fits into the mysterious category, and although it’s arguably a bit on the nose, it merges well with the twinkly extra effects that play when the reels spin or winning combinations make an appearance on the reels.

How to Win at the Book of Unseen Slot

The Book Of Unseen slot is played on a 5x3 grid with 10 betways. Winning combinations should feature between 3 and 5 identical symbols beginning from the leftmost position.

Top Winning Symbols

There are standard royal symbols that form the bottom half of the Book of Unseen paytable, but each one has been designed to fit in with the rest of the game’s design. The highest-value winning symbols include:

• Man


• Masked woman


• Ruby ring


• Golden key

On a 1.00 wager, landing 5 man symbols will award a 500.00-credit win. On the same 1.00 bet, landing 5 masked women symbols will unlock a 200.00-credit win and either 5 rings or 5 keys will add a 75.00-credit win to your playing balance.

Bet Limits

0.10 is the lowest wager that you can place per spin.

Book Of Unseen Bonus Features

Most Ruby Play slots have bonus features that can be triggered from the main base game, so let’s take a look at the extras on offer here.

Book Wild

The wild symbol has been designed to look like a mysterious book, and it has the ability to replace all symbols on the paytable. The game’s book wild symbol can also pay out its own wins, with 5 of a kind triggering a 100.00-credit win on a 1.00 wager.

Free Spins Bonus Round

There is no scatter symbol present here, so it is the wild symbol that can launch the free spins bonus. Landing just 3 wilds anywhere on the reels will award this bonus round with guaranteed expansions.

The number of guaranteed expansions depends solely on the number of wilds that trigger the bonus round:

• 3 x wild = 4 guaranteed expansions


• 4 x wild = 6 guaranteed expansions


• 5 x wild = 10 guaranteed expansions

At the beginning of the free spins bonus, one symbol is randomly selected to become an expanding symbol. After every spin, the reels will be evaluated for winning combinations. Once any wins have been paid out, if there is an expanding symbol present on the reels, it will replace all other symbols on that reel.

The reels will then be evaluated once again for winning combinations.

Max-win 2,500x

Book Of Unseen Review Summary

If you like slots with plenty of mystery and intrigue, Book Of Unseen is one that you might like to add into your rotation. In addition to a solid design and slightly eerie in-game ambiance, there are some decent features on offer, including free spins and expanding symbols.

It would have been preferable to also have a win multiplier bonus here, but it’s a compromise many slots players will be okay with making as there’s a lot to like about the game regardless.
