Book of Secrets Extra picks up where the previous games left off with free spins and gamble features. These are the two main mechanics in this slot and both work together pretty well.
The free spins round is triggered when 3 or more wild symbols land on the reels. 10 spins are awarded and a special symbol is chosen at the start of the round. After the payout of regular wins, the special symbol can expand leading to even bigger wins.
Players will have the chance to gamble the win up to 10 times! They will have to select whether the card will be red or black. Winning will double the win, whilst losing will take away the win entirely.
Like most of the other Book of Secret slots, free spins are triggered by landing 3 or more wilds. This leads to 10 free spins and one symbol being selected as the special expanding symbol.
After every win, players will have the option to gamble to try to double up the win. This can occur up to 10 times and players must decide on what the next card could be - but this comes with a risk.
The Book of Secrets slot series is one of the biggest franchises going from SYNOT Games. It all started with the original Book of Secrets and was revitalised with Book of Secrets 6.
Fans of the series will be delighted to know that the series continues on with the next instalment Book of Secrets Extra. Just like the original game, this adventure slot plays on 5-reels with 10 paylines and contains free spins, expanding symbols and SYNOT Games' trademark gamble feature.
Little has changed from the original game to this one, but that's not to say that the design is bad. When the slot opens up, players will be welcomed into an Ancient Egyptian temple surrounded by statues.
On the reels, players will find the greatest treasures with a variety of different symbols such as bejewelled scarab beetles and ankhs. Of course, the heroine is also featured on the reels with her look mainly unchanged.
The key element of this slot has to be the music throughout. There is an Egyptian score that just fits into the slot brilliantly and certainly delivers an intense experience to the player.
Ultimately, the gameplay for this slot is like any other 'Book Of' slot but with the added bonus of the 'gamble' mechanic. The free spins are entertaining but the gamble feature is where the biggest wins and most tense moments come in.
Like most SYNOT Games slots, the menus can be found at the bottom of the screen. The spin button and bet level button are at the bottom right. It's worth pointing out that the 'gamble' mechanic can be found here as well.
The Book of Secrets slots contain amazing win potentials that are truly remarkable. Book of Secrets and Book of Secrets 6 contain maximum wins of 6,227x and 10,000x stake respectively.
Thankfully, this game does not disappoint either as players can win up to 5,000x stake in the base game alone! Players can even win up to 6,525x the stake through the game as well which is more than the original! If a player lines up our heroine in all of the paylines, then a tasty 5,000x the stake will be all for them. This blends well with the above-average RTP of 96.07% and the medium-high volatility level.
Book of Secrets Extra does exactly what it says on the tin! It provides extra excitement to fans of the slot series and gives them a fresher experience. None of the gameplay has been revolutionised making it ideal for players wanting to experience the joy of Book of Secrets all over again.
Of course, we'd love it if something unique was added to the slot such as the Eclipse feature from Masters of Eclipse or the Zeus feature from Zeus Wild Thunder - but we'll happily wait to see this in the next Book of Secrets slot.
Fans of the original game will feel like they are returning home all over again with Book of Secrets Extra.
